- Model 2882-LS - Probe Mounted Solid/Liquid Level Switch

From

0

Reliable level alarm and control of liquids and solids. As a liquid or solid rises or lowers around the probe, the capacitance field changes. This is monitored and used to control the two on-board relays. Each relay includes full differential control to allow the relay to activate and de-activate between two distinct at user determined points on the probe. This can be used for pump and valve control between high and low level points. Adjustable time delay is standard to suppress spurious alarms from turbulence.

  • no moving parts
  • electronics is integral to the probe
  • high corrosion resistant Teflon and stainless steel wetted parts
  • capacitance technology responds to all product types
  • HF capacitance technology does not require routine cleaning
  • easy calibration and control set-up
