Differential Pressure Transmitters

The Pascal-ST/ZB bidirectional differential pressure transmitters are mainly used for clean room applications where accuracy and reliability are a must and space is limited

The measurement technology is based on the static principle with piezo-resistive bidirectional membrane.

The state-of-the-art electronics and firmware in combination with the automatic zero-point calibration allow very accurate and stable readings without any drift.

Pascal -ST/ZB models are available for 2 measurement ranges, -25 to +25 and -100 to +100 Pa.

Depending on the application, various model types are available, with integrated alarm switches or with analogue output, with or without display.

All instruments can be programmed, configured and adjusted using the PascalTool-WIN PC software.

The Pascal-STV/ZB disposes of a scalable and adjustable analogue output (mA or V). This makes it fi t for integration and adaptation to controlling systems (PLC). A digital output (RS-232) is also integrated by default.

This compact size product range among differential pressure measuring instruments excels by robust design and highest long-term performance.
