Static Pressure Sensor for High Temperature Applications

The AutoPSI-DC is designed for static and dynamic pressure measurements in harsh environments characterized by high temperature up to 300°C, high levels of Electromagnetic and Radio Frequency Interference fields (EMI/RFI), and chemically volatile media.

The sensor targets the following applications:

  • The plastic industry, specifically in the monitoring of injection molding and extrusion

  • Monitoring and control of compressor pressure in natural gas pumping stations

    •
  • Die-casting, turbine engines, oil exploration

    		•

    Housed in a robust and low-cost package, the AutoPSI-DC signal conditioner is contained in a metal cylinder 1.5” (~3.8cm) in diameter and 4” (~10cm) long, permanently connected to a 6.5’ (~2m) long and high-temperature (200°C) cable. The sensor is powered by a DC source and provides pressure output of 0-5V, 0.5-5V, or 0-10V.

    The AutoPSI-DC sensor is available in a sealed gauge pressure package, with a non-corrosive and non-abrasive metal diaphragm. It is available in all standard Optrand sensor packages, with non-linearity & hysteresis of ±1% or ±0.5% and a frequency range of 0Hz to 15kHz. The sensor is also available in custom packages.
