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-39X series measure the pressure difference indirectly using two absolute pressure sensors. The dual-sensor design with numerical differential formation also outputs the line pressure values via the digital RS485 interface and guarantees a high overload resistance. The additional analog current or voltage output is primarily used to output the differential pressure range, which is freely rangeable within the line pressure range.

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 series 13 pressure transducers have internal water cooling and are suitable for use in media temperatures of up to 350 °C. Typical applications include superheated steam circuits, engine test benches or chemical process monitoring.

The differential pressure transmitters of the PD-23 series are designed for industrial applications and are supplied with a G1/4 internal thread as standard. They are based on a fully analog circuit. The PD-23 transmitters 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 tiny pressure differences even at an extremely high line pressure.

The capacitive pressure transmitters of the PD-41X series are designed for measuring differential pressure values in the mbar and µbar range. They use digital compensation with a mathematical model to achieve an accuracy of 0,1 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band. In addition to the digital RS485 interface, the X-line transmitters have a rangeable analog current or voltage output.

The high-pressure transducers of the 6LHP series have a robust housing made of stainless steel, giving them optimum long-term stability for a range of OEM applications.
