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 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.
Each product is individually tested, calibrated and compensated for drift related to temperature changes. Calibration data is stored in the internal non-volatile memory.
The PSM-2 can be supplied with DAkkS certified calibration certificate.
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.
The integrated sensor heat sink limits the heat transfer from the process media to the sensor electronics and allows process media temperatures up to 150 °C.
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.
The transmitter can be delivered with a custom configuration to match specific application and requirements. Examples of customized options include 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.
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.
The PSM-2 is available in versions with traditional analog output (e.g. 4-20 mA and 0-10 VDC) and various optional digital interfaces.
S4-Connect™ is a flexible and cost-effective communication programmer for configuration device for pressure and temperature transmitters and transducers
