Series 25Y

The pressure transmitters of the 25Y-Ei series with a front-flush separating diaphragm are designed for elevated requirements in industrial applications and are supplied with a G1/2" male pressure port. Thanks to its modular concept, this series is highly flexible and makes it possible to realise customer-specific requirements in very little time. The sophisticated compensation circuit makes it possible to specify a narrow total error band. Intrinsically safe – suitable for use in explosive atmospheres.

The differential pressure transmitters of the PRD-33X series are designed for accurate measurements in low pressure ranges with very high overload on both sides. In addition to the differential pressure sensor, which may only be exposed to gases at its rear face, the devices have an additional absolute pressure sensor that measures the line pressure. Both measured values are output via the digital RS485 interface and are the ideal basis for cryogenic tank monitoring.

The differential pressure transmitters of the PD-33X series are suitable for 'wet/wet' applications. They have a single silicon diaphragm in their interior, which is pressurised from both sides and measures the pressure difference directly. This design enables them to measure small pressure differences even at an extremely high line pressure. The transmitters use digital compensation with a mathematical model to achieve exceptional accuracy of 0,05 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band.

The ultra-fast M8coolHB pressure transmitter can process pressure changes with a bandwidth of 50 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M8 thread can withstand temperatures of up to 1000 °C with suitable cooling, is overload-proof up to a magnitude of five times the measuring range, and is also resistant to vibrations.
