The PSM-1 series pressure transmitter is designed for gas, vapor and liquid measurement in a variety of industrial applications.  Its modular compact design offers a unique combination of high measurement performance, flexible configuration and a robust stainless steel design.

The PSM-1 is user programmable and configurable from a PC through the novel S4-Connect interface.

Sensor technology

absolute pressure sensor
gauge pressure sensor

The PSM-1 is based on a stainless steel sensor diaphragm that converts the applied pressure to an electric signal. The sensor has internal filling-oil that transforms the applied pressure to the MEMS piezo sensor element.

It is available either as an absolute sensor that measures relative to an integrated sealed reference vacuum or as a gauge sensor that measures relative to the ambient pressure.

The stainless steel sensor surface in combination with the 316 stainless steel flange offers excellent chemical resistance and compatibility with a wide range of aggressive gases, solvents and acids.   

Measurement performance

Each product is individually tested, calibrated and compensated for drift related to temperature changes.

Calibration data is stored in the internal non-volatile memory.

Advanced enclosure design

The IP67 sealed 316 stainless steel enclosure with integrated hydrophobic membrane is designed for extreme environments. The innovative moisture control barrier prevents internal moisture accumulation and water condensation when changes in ambient pressure, temperature and humidity occur. Gauge pressure sensors measures relative to ambient pressure and the hydrophobic membrane provides pressure equalization when the ambient pressure changes, e.g. due to changes in the weather or altitude.

S4-Connect™ programmer

The innovative S4-Connect™ USB digital communication interface provides access to the powerful digital core. It enables digital communication over the power supply line, thus eliminating the need for additional connector pins. The interface can be used for diagnostics, maintenance, service, calibration, setpoint configuration, analog output scaling and setting of other customized parameters. Furthermore, the products offer pin compatibility with industry standard pin-outs for analog transducers.

Customized settings

The transmitter can be delivered with a custom configuration to match specific application and requirements. Examples of custom configured options are measurement range, pressure unit, setpoint configuration and output signal scaling. Customized products will be assigned a unique part number for easy and simple future re-ordering.

Process pressure control and surveillance

The optional setpoint can be either used for controlling or surveillance of the measured pressure via a solid-state relay. The basic control uses on/off regulation with a programmable setpoint and hysteresis value.

Analog and digital output options 

The PCM-1 is available in versions with traditional analog output (e.g. 4-20 mA and 0-10 VDC) and various optional digital interfaces.
