photo - 121A Baratron Absolute Pressure/Vacuum Transmitter (1 - 25,000 Torr) with Bakeable Sensor and Remote Electronics

The MKS 121A Baratron® Capacitance Manometer employs a remote sensor which can operate at up to 150°C (bakeable to 200°C) for critical processing applications. The sensor and electronics are separated by an eight foot cable that allows the electronics to be mounted away from heat sources.

Features & Benefits:

  • All-metal sensor eliminates problems associated with glass, mercury, and liquid gauges
  • Useable resolution of 1 part in 10,000 minimizes the number of transducers needed to cover a wide range of pressure
  • Remote electronics allow the sensor to operate at temperatures up to 150°C (bakeable to 200°C with cable removed)
  • Inconel®/Stainless Steel sensors resist corrosion
