Magnetic sensors product, Intelligent sensing solutions

The PST pressure transmitter or pressure sensor is a high-performance instrument intended for industrial applications where the process media is compatible with the SUS316L stainless steel sensor material and the 304 SS process connection.

The PST pressure sensors employ a piezoresistive effect in silicon. Piezoresistor as a resistor is made from a piezoresistive material, the resistance of which changes with the variable mechanical stress

The sensor is welded to a pressure fitting of stainless steel or brass that provides a high overpressure capability and excellent durability against shock and vibration. The transducer circuitry is held securely within an internal cage and housed in a reinforced nylon and EPDM enclosure.

Features
  • Affordable performance in a compact, durable housing package
  • ±1% error of span
  • High EMI/RFI compatibility
  • High temperature resistance
  • High accuracy is accomplished by marrying a high-performance ASIC to a very stable polysilicon thin film pressure sensor
  • Wide measurement range
  • All stainless steel structure
  • Reverse polarity protection
  • Strong capacity of resisting disturbance
  • Long-term stability
