The PSM-2 series programmable pressure transmitter is designed for gas, vapor and liquid measurement in pharmaceutical, food, beverage, and biotechnology applications. The transmitter is compatible with the temperature and chemical exposure used in industrial standard CIP (Clean-in-place) and SIP (Steam-in-place) cleaning processes.
The PSM-2 is programmable and configurable from PC via the novel S4-Connect™ interface.
Sensor technology
The PSM-2 is based on a stainless steel 316L diaphragm that converts the applied pressure to an electric signal. The sensor diaphragm is flush with the flange and has a surface roughness RA value of less than 0.38 µm. The flush sensor diaphragm enables use in applications with pressure media with high viscosity that can clog small sensor cavities. The sensor element uses an internal FDA approved filling fluid to transfer the pressure from the sensor diaphragm to the 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.
APPLICATIONS
- Food and beverage processing
