Easy Rate Single Sensor


Easy Rate Single Sensors can maximize production while minimizing cost. These sensors maximize availability with extended sensor life and reduced maintenance. They also minimize production cost due to their lower initial investment and total cost of ownership. They are reliable sensors with parts that can be conveniently replaced in the field.

Providing the most cost effective solution for thickness monitoring, the INFICON Easy Rate Single Sensor is available with standard or right angle orientations, and they can be configured to include a feedthrough with or without bored-through tube fittings.

Note: Easy Rate Single sensors use 4.8 mm (3/16 in.) outer diameter (OD) water cooling tubes.  They are not compatible with Ultra-Torr equipped Front Load Sensor feedthroughs and require a tubing adapter in order to be welded to a standard feedthrough with 4.8 mm (3/16 in.) OD water cooling tubes.

Features

  • Minimum investment with lowest upfront cost
  • Lowest total cost of ownership from extended sensor life
  • Maximum throughput with less maintenance
  • Easy installation
  • Available in standard and right angle configurations
  • Optional shutter available
  • Sensor / Feedthrough combinations available with or without bored-through tube fittings
