The AMETEK DTI-1000 can be used with compatible reference temperature sensors to measure the actual temperature of a calibration medium.
This is particularly important when calibrating temperature sensors using a dry block calibrator.
The displayed temperature of a dry block calibrator may differ slightly from the actual temperature at the position of the device under test.
By using the AMETEK DTI-1000 with a suitable reference thermometer, the actual calibration temperature can be determined independently.
This allows more accurate comparison calibrations.
Temperature Measurement Range from −200 °C to +750 °C
The AMETEK DTI-1000 provides a temperature measurement range of:
−200 °C to +750 °C
This wide measurement range covers numerous industrial and laboratory temperature applications.
Typical measurement temperatures include:
- −200 °C
- −100 °C
- −50 °C
- 0 °C
- +100 °C
- +200 °C
- +400 °C
- +600 °C
- +750 °C
The usable temperature range depends on the connected reference sensor.
For example, the STS-100 reference sensor is designed for temperatures from −150 °C to +650 °C.
The STS-102 reference sensor covers temperatures from −50 °C to +155 °C.
The STS-050 reference sensor covers temperatures from −50 °C to +400 °C.
The complete measurement system must therefore be selected according to the required temperature range and measurement uncertainty.
High Measurement Accuracy
The AMETEK DTI-1000 provides excellent measurement accuracy.
The manufacturer specifies an instrument accuracy down to:
±0.004 °C
This value refers to the instrument electronics under specified conditions and does not include the uncertainty of the connected temperature sensor.
The DTI-1000 is available in two configurations.
AMETEK DTI-1000A
The DTI-1000A supports Pt100 and Pt25 reference temperature sensors.
The specified resistance measurement accuracy over 12 months is:
±(6 ppm of reading + 1.4 mΩ)
AMETEK DTI-1000B
The DTI-1000B is designed for Pt25 reference temperature sensors.
The specified resistance measurement accuracy over 12 months is:
±(6 ppm of reading + 0.7 mΩ)
The temperature measurement accuracy depends on the sensor type, temperature and calibration coefficients.
For professional calibration applications, the uncertainty of the complete measurement system must be considered.
High Resolution of 0.001 °C
The AMETEK DTI-1000 provides selectable temperature resolution.
Available settings include:
0.1 °C, 0.01 °C and 0.001 °C
The high resolution allows small temperature changes to be observed.
This is particularly useful when monitoring the stability of temperature calibration equipment.
The instrument can detect small variations in the temperature of a liquid bath or dry block calibrator.
High resolution also helps users evaluate temperature stability during comparison calibrations.
However, display resolution must not be confused with measurement accuracy.
The measurement uncertainty depends on the instrument, connected sensor and calibration conditions.
Dual Channel Temperature Measurement
The AMETEK DTI-1000 features two independent measurement channels.
This allows two temperature sensors to be connected simultaneously.
The instrument can display both temperature readings.
This is particularly useful for comparison measurements.
For example, one channel can be connected to a calibrated reference thermometer.
The second channel can be connected to another compatible temperature sensor.
Both sensors can then be measured under identical temperature conditions.
This simplifies temperature comparison measurements and reduces the need for additional measuring instruments.
Differential Temperature Measurement
The AMETEK DTI-1000 supports differential temperature measurement.
The instrument can calculate the temperature difference between its two measurement channels.
The differential temperature is determined by:
ΔT = T₁ − T₂
This function is particularly useful when comparing two temperature sensors.
It can also be used to investigate temperature differences within calibration equipment.
Typical applications include:
- Comparison of two reference thermometers
- Temperature difference measurements
- Temperature uniformity investigations
- Temperature stability monitoring
- Sensor comparison measurements
The differential measurement function provides a convenient way to evaluate small temperature differences.
True Ohm Measurement Technology
The AMETEK DTI-1000 uses advanced True Ohm measurement technology.
This technology is designed to minimize errors caused by thermoelectric voltages in measurement cables, connectors and sensors.
Thermoelectric voltages can occur when different conductive materials are exposed to temperature gradients.
These voltages can influence precision resistance measurements.
The AMETEK DTI-1000 compensates for these effects by performing measurements with and without the excitation current.
The instrument first measures the sensor resistance using a defined measurement current.
It then performs an additional measurement without the excitation current.
This allows the influence of unwanted thermoelectric voltages to be determined and compensated.
The result is improved resistance measurement accuracy.
Four-Wire Resistance Measurement
The AMETEK DTI-1000 uses four-wire resistance measurement technology.
This measurement method separates the current-carrying conductors from the voltage-sensing conductors.
The four-wire configuration minimizes the influence of lead resistance.
This is particularly important when measuring precision resistance thermometers.
The instrument uses a measurement current of:
1 mA
Four-wire resistance measurement is an established method for accurate temperature measurement using platinum resistance thermometers.
Integrated Reference Resistors
The AMETEK DTI-1000 contains high-precision internal reference resistors.
These components are designed to provide excellent long-term stability.
Stable reference resistors help minimize measurement drift over time.
This is particularly important for instruments used as working standards in calibration laboratories.
The instrument is designed for applications requiring reliable measurement performance between recalibration intervals.
Regular calibration is recommended to verify long-term measurement accuracy.

The appropriate reference sensor should be selected according to the required temperature range, sensor dimensions and measurement uncertainty.
System Accuracy with STS Reference Sensors
The AMETEK DTI-1000 can be combined with compatible STS reference temperature sensors to form a complete reference thermometer system.
The manufacturer specifies system accuracy down to:
±0.03 °C
This specification depends on the selected reference sensor and operating range.
For example, certain STS-100 configurations provide a specified system accuracy of ±0.03 °C over a defined temperature range.
The manufacturer provides separate specifications for different sensors and temperature ranges.
These specifications include the relevant calibration uncertainty under the stated conditions.
For demanding applications, the actual calibration certificate and sensor drift must be considered.
Temperature Conversion and Sensor Characteristics
The AMETEK DTI-1000 converts measured resistance values into temperature.
Accurate temperature conversion requires suitable sensor characteristics.
The instrument supports the use of calibration coefficients for compatible platinum resistance thermometers.
This allows the individual characteristics of a reference sensor to be considered.
The use of individual calibration coefficients can improve temperature measurement accuracy compared with a generic sensor characteristic.
For high-accuracy measurements, the calibration coefficients should be taken from the current calibration certificate of the connected sensor.
Fast Measurement Response
The AMETEK DTI-1000 provides different measurement update rates depending on the selected resolution.
| Resolution | Update Time |
|---|---|
| 0.1 °C | 2 seconds |
| 0.01 °C | 3 seconds |
| 0.001 °C | 12 seconds |
The user can select the appropriate resolution according to the measurement task.
A lower resolution allows faster measurement updates.
The highest resolution provides more detailed temperature readings.
This flexibility is particularly useful for temperature stability measurements and precision calibration applications.
