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
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.
