The Heldon E-9400 Level Switches series liquid level switches use infrared light reflecting from a conical glass prism moulded in the sight glass as a means of detecting the absence of a fluid at the level of the glass cone.

When no fluid covers the lower half of the cone, infra-red light from the module reflects from the mirror-like inner surface of the cone back to a light detector signaling the electronic module to switch. When fluid covers the lower half of the glass cone, the light from the module passes into the fluid.

This absence of light is detected by the module, which switches into the opposite direction. The module provides a .06/.10 differential distance from the cone point down.

Features:

  1. Eliminates mechanical floats.
  2. Reduces number of connections required on liquid level columns by mechanical floats.
  3. Provides automatic control of pumps, valves, high and low alarms, and cut-outs.
