optek offers a wide variety of process photometric sensors designed specifically to meet the demanding requirements for many industrial process applications. They can offer Process In-Line Sensors as well as Process Insertion Probe Sensors, using either Scattered Light or Absorption Technologies.

When choosing an PHOTOMETRIC SENSOR , it is important to choose a photometric sensor appropriate for the process application intended for. We will gladly assist you in specifying the right sensor for the job. Here are a few of the required parameters to properly specify a sensor:

  • Species or constituents to measure
  • Concentration ranges
  • Line or Port Size
  • Process connection - adaptation method
  • Temperatures
  • Pressures
  • Wetted Materials - compatibility to process
  • pH of process medium (Acidic, Caustic)
  • Electrical classification (General Purpose or Hazardous Areas)
  • Environmental classification (NEMA Type)
  • Distance from Converter to Sensing Location
