Process Liquide Analytical

The Foxboro range of contacting conductivity and resistivity products comprises sensors, analyzers and transmitters. Sensor types include the 871CC and 871CR. Analyzers include the 875CR and 873 Series. The transmitter is the 876CR.

Common feature includes

  • Sensors are characterized by their wide range of mounting accessories, precision construction for high accuracy, rugged design and ease of use.
  • Analyzers include the 875CR and 873 Series. These are line powered instruments with measurement display, alarm contacts and analog outputs
  • The transmitter is the 876CR, which is a loop-powered, two-wire transmitter with a 4 to 20 mA output and HART communications.
  • Broadest range of electrodeless sensors to meet all application requirements
  • Safest sensor (871FT) for measuring dangerous chemicals due to calibration from outside the pipe
  • Patented calibration tool enables fast, accurate calibration
  • PEEK body electrodeless sensors do not rely on mechanical seals to protect sensor internals from process ingress.  The industry's most robust electrodeless sensors.
  • High accuracy contacting sensors for critical pure and ultrapure water measurements
  • High accuracy, Easy to install, remove and calibrate
  • High degree of safety
  • Flexible matching of materials to meet application requirements
