accurate temperature measurements over a wide temperature range.<\/p>\n<p><strong>Temperature range: \u2212200 \u00b0C to +350 \u00b0C<\/strong><\/p>\n<p>This range covers cryogenic temperature measurements, low-temperature calibration, ambient temperature measurements and elevated-temperature industrial applications.<\/p>\n<p>The Fluke Calibration 5622 is particularly suitable for applications requiring fast thermal response.<\/p>\n<p>Its small sensing elements allow rapid temperature measurements while maintaining the advantages of platinum resistance thermometry.<\/p>\n<p>The wide operating range makes the Fluke Calibration 5622 more versatile than many conventional thermistor probes.<\/p>\n<h2>Fast Thermal Response<\/h2>\n<p>One of the most important advantages of the Fluke Calibration 5622 is its exceptionally fast response to temperature changes.<\/p>\n<p>The manufacturer specifies response times as fast as:<\/p>\n<p><strong>0.4 seconds<\/strong><\/p>\n<p>This performance is achieved through the compact construction and small thermal mass of the sensing element.<\/p>\n<p>The small probe diameter allows heat to be transferred quickly between the measurement medium and the platinum resistance element.<\/p>\n<p>This is particularly useful when measuring rapidly changing temperatures.<\/p>\n<p>The actual response time depends on the selected probe model and the measurement conditions.<\/p>\n<h2>Four Different Probe Diameters<\/h2>\n<p>The Fluke Calibration 5622 series includes four different probe models.<\/p>\n<p>Each model is designed for specific measurement requirements.<\/p>\n<h3>Fluke Calibration 5622-05<\/h3>\n<p><strong>Probe diameter: 0.5 mm<\/strong><\/p>\n<p><strong>Probe length: 100 mm<\/strong><\/p>\n<p><strong>Minimum immersion depth: 10 mm<\/strong><\/p>\n<p><strong>Time constant: 0.4 seconds<\/strong><\/p>\n<p>The Fluke Calibration 5622-05 is the smallest and fastest probe in the series.<\/p>\n<p>Its extremely small diameter makes it particularly suitable for temperature measurements in narrow openings and confined spaces.<\/p>\n<h3>Fluke Calibration 5622-10<\/h3>\n<p><strong>Probe diameter: 1.0 mm<\/strong><\/p>\n<p><strong>Probe length: 100 mm<\/strong><\/p>\n<p><strong>Minimum immersion depth: 20 mm<\/strong><\/p>\n<p><strong>Time constant: 1.5 seconds<\/strong><\/p>\n<p>The Fluke Calibration 5622-10 combines fast response with a slightly larger probe diameter.<\/p>\n<p>It is suitable for applications requiring rapid temperature measurements and relatively shallow immersion.<\/p>\n<h3>Fluke Calibration 5622-16<\/h3>\n<p><strong>Probe diameter: 1.6 mm<\/strong><\/p>\n<p><strong>Probe length: 200 mm<\/strong><\/p>\n<p><strong>Minimum immersion depth: 32 mm<\/strong><\/p>\n<p><strong>Time constant: 3.0 seconds<\/strong><\/p>\n<p>The Fluke Calibration 5622-16 provides a balance between mechanical robustness and thermal response.<\/p>\n<p>Its longer sheath allows use in a wider range of calibration equipment.<\/p>\n<h3>Fluke Calibration 5622-32<\/h3>\n<p><strong>Probe diameter: 3.2 mm<\/strong><\/p>\n<p><strong>Probe length: 200 mm<\/strong><\/p>\n<p><strong>Minimum immersion depth: 64 mm<\/strong><\/p>\n<p><strong>Response time: 10 seconds at 90% response<\/strong><\/p>\n<p>The Fluke Calibration 5622-32 is the most robust version in the series.<\/p>\n<p>Its larger diameter provides greater mechanical strength while maintaining good thermal response.<\/p>\n<h2>Small Immersion Depth<\/h2>\n<p>The Fluke Calibration 5622 is particularly suitable for applications where only limited immersion depth is available.<\/p>\n<p>Depending on the selected version, the minimum immersion depth ranges from:<\/p>\n<p><strong>10 mm to 64 mm<\/strong><\/p>\n<p>This is significantly less than the immersion depth required by many conventional reference thermometers.<\/p>\n<p>A short immersion depth allows accurate temperature measurements in small containers and confined measurement locations.<\/p>\n<p>The compact sensing element helps reduce the influence of heat conduction along the probe stem.<\/p>\n<p>However, immersion effects should still be evaluated when performing high-accuracy calibration.<\/p>\n<h2>Precision Platinum Resistance Element<\/h2>\n<p>The Fluke Calibration 5622 uses a precision platinum resistance sensing element.<\/p>\n<p>Platinum is widely used in temperature metrology because its electrical resistance changes reproducibly with temperature.<\/p>\n<p>The Fluke Calibration 5622 features a nominal resistance of:<\/p>\n<p><strong>100 \u03a9<\/strong><\/p>\n<p>The nominal temperature coefficient is:<\/p>\n<p><strong>0.00385 \u03a9\/\u03a9\/\u00b0C<\/strong><\/p>\n<p>This corresponds to the standard industrial platinum resistance characteristic.<\/p>\n<p>The sensor resistance is measured using a suitable precision thermometer readout.<\/p>\n<p>The readout converts the measured resistance into temperature using the selected calibration characteristic.<\/p>\n<h2>Four-Wire Resistance Measurement<\/h2>\n<p>The Fluke Calibration 5622 uses a four-wire electrical connection.<\/p>\n<p>Four-wire measurement minimizes errors caused by connecting lead resistance.<\/p>\n<p>In a two-wire connection, the resistance of the connecting leads contributes to the measured resistance.<\/p>\n<p>This can introduce temperature measurement errors.<\/p>\n<p>Four-wire measurement separates the current and voltage connections.<\/p>\n<p>This allows the resistance of the platinum sensing element to be determined more accurately.<\/p>\n<h2>Stainless Steel 316 Sheath<\/h2>\n<p>The <strong>Fluke Calibration 5622<\/strong> features a stainless steel 316 sheath.<\/p>\n<p>This material provides mechanical protection and corrosion resistance for many laboratory and industrial applications.<\/p>\n<p>The sheath protects the precision platinum sensing element.<\/p>\n<p>Its small diameter allows fast heat transfer between the measurement medium and the sensor.<\/p>\n<p>Chemical compatibility should be considered when the probe is exposed to aggressive measurement media.<\/p>\n<h2>Calibrated Probe Accuracy<\/h2>\n<p>The Fluke Calibration 5622 provides excellent calibrated measurement accuracy.<\/p>\n<p>The manufacturer specifies different accuracy values depending on the selected probe diameter.<\/p>\n<h3>Fluke Calibration 5622-05 and 5622-10<\/h3>\n<table>\n<tbody>\n<tr>\n<th>Temperature<\/th>\n<th>Calibrated

thermometer readout and measurement conditions.<\/p>\n<h2>ITS-90 Comparison Calibration<\/h2>\n<p>The Fluke Calibration 5622 can be supplied with an individual ITS-90 comparison calibration.<\/p>\n<p>The manufacturer offers calibration services covering seven temperature points from approximately:<\/p>\n<p><strong>\u2212197 \u00b0C to +300 \u00b0C<\/strong><\/p>\n<p>The calibration provides individual coefficients for accurate temperature conversion.<\/p>\n<p>These coefficients describe the resistance-temperature relationship of the specific probe.<\/p>\n<p>When entered into a compatible thermometer readout, the individual calibration coefficients allow more accurate temperature measurements than a generic nominal sensor characteristic.<\/p>\n<h2>Optional Accredited Calibration<\/h2>\n<p>An accredited comparison calibration is available for the Fluke Calibration 5622.<\/p>\n<p>The calibration provides documented measurement results and supports metrological traceability.<\/p>\n<p>The selected calibration option should be checked when ordering.<\/p>\n<p>For high-accuracy applications, the uncertainty stated on the individual calibration certificate should be considered.<\/p>\n<h2>Compatible Thermometer Readouts<\/h2>\n<p>The Fluke Calibration 5622 is a passive platinum resistance thermometer.<\/p>\n<p>It does not include an integrated temperature display.<\/p>\n<p>A suitable precision thermometer readout is required.<\/p>\n<p>Compatible instruments include:<\/p>\n<ul>\n<li>Fluke Calibration 1523<\/li>\n<li>Fluke Calibration 1524<\/li>\n<li>Fluke Calibration 1529<\/li>\n<li>Other compatible precision resistance thermometer readouts<\/li>\n<\/ul>\n<p>The selected connector must match the thermometer readout.<\/p>\n<h2>Intelligent Sensor Connectors<\/h2>\n<p>The Fluke Calibration 5622 is available with different connector options.<\/p>\n<p>Compatible INFO-CON connectors can store individual calibration coefficients.<\/p>\n<p>When connected to a suitable Fluke Calibration thermometer readout, the coefficients can be retrieved automatically.<\/p>\n<p>This simplifies instrument configuration and reduces the risk of incorrect calibration data entry.<\/p>\n<p>The availability of this function depends on the selected connector and thermometer readout.<\/p>\n<h2>Available

should be selected according to the thermometer readout.<\/p>\n<h2>Temperature Comparison Calibration<\/h2>\n<p>The Fluke Calibration 5622 is particularly suitable for temperature comparison calibration.<\/p>\n<p>A calibrated reference thermometer and a device under test are placed in the same stable temperature source.<\/p>\n<p>After thermal equilibrium has been reached, both temperature values are recorded.<\/p>\n<p>The indication error is calculated as:<\/p>\n<p><strong>\u0394T = T_DUT \u2212 T_REF<\/strong><\/p>\n<p>Where:<\/p>\n<ul>\n<li>\u0394T = Temperature indication error<\/li>\n<li>T_DUT = Temperature indicated by the device under test<\/li>\n<li>T_REF = Reference temperature<\/li>\n<\/ul>\n<p>The measurement uncertainty depends on the reference thermometer calibration, readout accuracy and temperature source.<\/p>\n<h2>Temperature Measurements in Confined Spaces<\/h2>\n<p>The small probe diameters of the Fluke Calibration 5622 allow temperature measurements in confined spaces.<\/p>\n<p>The smallest version has a diameter of only 0.5 mm.<\/p>\n<p>This allows the probe to be inserted into narrow measurement openings.<\/p>\n<p>The compact construction also reduces the thermal disturbance caused by the sensor.<\/p>\n<p>This is particularly useful when measuring temperatures in small volumes.<\/p>\n<h2>Dynamic Temperature Measurements<\/h2>\n<p>The Fluke Calibration 5622 is suitable for applications involving changing temperatures.<\/p>\n<p>Its fast response allows temperature variations to be detected quickly.<\/p>\n<p>The 5622-05 version provides a time constant of only 0.4 seconds under the specified test conditions.<\/p>\n<p>This makes it particularly useful for monitoring rapid temperature changes.<\/p>\n<p>The actual dynamic response depends on the measurement medium and installation.<\/p>\n<h2>Calibration Baths<\/h2>\n<p>The Fluke Calibration 5622 can be used in compatible liquid calibration baths.<\/p>\n<p>The small probe diameter allows the sensor to be positioned in narrow calibration openings.<\/p>\n<p>The short immersion requirements make the probe particularly useful for shallow calibration baths.<\/p>\n<p>For high-accuracy measurements, the temperature stability and uniformity of the bath must be considered.<\/p>\n<h2>Dry-Block Temperature Calibration<\/h2>\n<p>The Fluke Calibration 5622 can also be used with suitable dry-block temperature calibrators.<\/p>\n<p>The small probe diameter allows measurements in narrow calibration inserts.<\/p>\n<p>The reference thermometer measures the temperature of the calibration zone.<\/p>\n<p>This allows the actual temperature to be compared with the indication of the device under test.<\/p>\n<h2>Technical
