Pascal-ST/ZB

Differential pressure measurement instruments

Thanks to outstanding sensor technology, optimized measurement electronic, software, and an integrated automatic zero-point calibration, these instruments excel with their accurate and stable readings.

Various functions for adjustment, password protection, measurement filters and intervals, scalable outputs as well as alarm settings emphasize the versatility of this instrument. Its application areas are consequently vast and it is ideal for demanding controls.

For the first time ever a membrane differential pressure instrument offers such outstanding performances at such competitive prices!

The Pascal-ST/ZB differential pressure measuring devices are precision instruments for monitoring and controlling pressure differences of gaseous media in low ranges. The measurement principle is based on static differential pressure detection with a silicon membrane.

Besides high robustness and accuracy, these devices offer easy and intuitive handling and start-up. The zero calibration is performed automatically and so the instrument is ready for use immediately after its installation.

Main features:

Measurement ranges : -25…+25 Pa / -100 …+100 Pa
Measurement accuracy at 20°C : 25 Pa instruments +/-0.3%

100 Pa instruments +/-0.1%

Hysteresis : +/- 0.15 Pa
Typical offset drift : +/-0.15 Pa

Calibox 200

A portable differential pressure calibrator & reference measurement instrument

This new differential pressure generator and reference instrument has been designed for laboratories as well as for mobile use in clean rooms. Thanks to its rechargeable battery, the device can be operated for up to 48 hours independent from any external power source.

At the push of a button, the generator becomes a real reference measurement device, if required also available with an accredited certificate. The internal sensor operates with high accuracy and long-term stability, which is achieved with a combination of a high-quality sensor element and a fully automated zeroing system. This makes the instrument not just accurate but also maintenance-free!

But the CaliBox 200 offers more! Its steady and stable pressure generation allows the calibration of static membrane and dynamic mass flow sensors. Hence this all-rounder can be used for most of the differential pressure measurement technologies. Other strengths are mechanical and pressure robustness.
