Four Low-Pressure Ranges

The europascal EPC-LP is available in four different measuring and control ranges.

The available versions are:

EPC-LP 1 – 1 hPa

EPC-LP 10 – 10 hPa

EPC-LP 100 – 100 hPa

EPC-LP 1000 – 1,000 hPa. EPC-LP Pressure Calibrator euro…

This selection makes the EPC-LP suitable for extremely low differential and pneumatic pressure applications.

A 1 hPa full-scale range corresponds to only 100 Pa, while the largest 1,000 hPa version covers pressures up to 100,000 Pa.

The appropriate version can therefore be selected according to the pressure range of the device under test.

Integrated Pressure Generation

One of the most important features of the europascal EPC-LP is its:

internal pressure generation. EPC-LP Pressure Calibrator euro…

The EPC-LP does not simply measure an externally generated pressure. It can generate the required pressure itself and regulate it to the desired calibration point.

This significantly simplifies a calibration setup.

Instead of requiring a separate pressure generator, regulator and pressure measuring instrument, the essential pressure functions are combined in one device.

This is especially advantageous for mobile calibration tasks.

Pressure Measurement and Control

The EPC-LP combines measurement and pressure control.

According to the supplied europascal datasheet, the available pressure range can be used from:

-10% to 110% of the nominal range. EPC-LP Pressure Calibrator euro…

This extended usable pressure range provides additional flexibility around the nominal zero point and at the upper end of the selected measuring range.

Accuracy down to 0.1% FS

Depending on the selected EPC-LP version, the specified overall accuracy is:

0.3% FS

or:

0.1% FS.

The adjustment accuracy is specified as:

0.05%. EPC-LP Pressure Calibrator euro…

The datasheet defines overall accuracy as the maximum permissible deviation of the sensor output from the applied pressure value. It includes measurement errors caused by linearity, hysteresis and repeatability. EPC-LP Pressure Calibrator euro…

This provides a clear specification for evaluating the measurement performance of the calibrator.

Fast Pressure Settling

For efficient calibration procedures, the EPC-LP provides a specified settling time of:

less than 5 seconds. EPC-LP Pressure Calibrator euro…

Fast settling reduces waiting time between individual calibration points.

This becomes particularly useful when several pressure points must be generated repeatedly or when programmable pressure profiles are used.

Excellent Long-Term Stability

Long-term stability is specified as:

< ±0.1% FS/year. EPC-LP Pressure Calibrator euro…

Long-term stability is an important parameter for calibration equipment because changes in the pressure sensor over time directly affect measurement performance.

The EPC-LP additionally provides zero-point adjustment to compensate for zero drift.

Automatic Zero-Point Adjustment

Zero balance can be performed automatically or manually.

The automatic function operates at:

adjustable time intervals.

Manual zero adjustment can be initiated using the dedicated:

ZERO button. EPC-LP Pressure Calibrator euro…

With automatic or manual zero-point adjustment, the datasheet specifies the corresponding zero contribution as 0.0%.

This functionality is particularly useful for low-pressure measurement, where even small zero offsets can represent a significant proportion of the measured pressure.

Low Temperature Drift

Temperature drift is specified as:

≤ 0.03% FS/K. EPC-LP Pressure Calibrator euro…

This parameter describes the influence of temperature changes on the measurement system.

For precision low-pressure calibration, stable environmental conditions nevertheless remain beneficial.

Inductive Measurement System

The europascal EPC-LP uses an:

inductive measurement system. EPC-LP Pressure Calibrator euro…

This measuring principle forms the basis of the internal pressure measurement.

The specified pressure medium is:

non-aggressive gases.

The EPC-LP should therefore only be operated with pressure media compatible with the manufacturer’s specification.

Three Operating Modes

The EPC-LP provides several operating modes for different calibration tasks.

CTRL – Regulate Pressure

In CTRL mode, the EPC-LP regulates the pressure.

This mode is used when the instrument must automatically establish and maintain a specified pressure.

MESS – Pressure Measurement

In MESS mode, the EPC-LP operates as a pressure measuring instrument.

This mode can be used when the applied pressure only needs to be measured.

AUTO – Freely Definable

The AUTO mode is freely definable and supports automated operating sequences.

In addition, the instrument can be operated remotely via its interfaces. EPC-LP Pressure Calibrator euro…

These different operating modes make the EPC-LP suitable for both manual and automated calibration processes.

Programmable Pressure Profiles

Programmable pressure profiles are an important feature of the europascal EPC-LP.

They allow individual calibration procedures to be automated. EPC-LP Pressure Calibrator euro…

Instead of manually entering each calibration point, a defined sequence of pressure values can be used.

This can improve repeatability and reduce the amount of manual intervention required during recurring calibration tasks.

Pressure Sensor Calibration

The EPC-LP is specifically designed for testing and calibrating:

pressure sensors. EPC-LP Pressure Calibrator euro…

Because pressure generation and pressure measurement are integrated into one device, the sensor under test can be connected directly to the calibration system.

The EPC-LP establishes the required test pressure, while the electrical output of the sensor can be evaluated with suitable measurement equipment.

Pressure Switch Testing

The europascal datasheet also explicitly identifies:

pressure switches

as devices that can be tested and calibrated with the EPC-LP. EPC-LP Pressure Calibrator euro…

For pressure-switch applications, controlled pressure generation is especially useful because the switching point can be approached systematically.
