The LLHP high performance level switches offer larger mounting threads and robust stainless steel housings that can survive in aggressive environments.
The microcontroller based sensor is solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.
A range of N and P type output configurations can sink or source up to 100mA at a supply voltage range from 4.5 to 15.4 Vdc or 800mA at a supply voltage range from 10 to 45Vdc, all of which can be configured to output a high or low signal in either a wet or dry state.
The LLHP high performance level switch combines a robust stainless steel housing with a chemically resistant Polysulfone or Trogamid sensing tip and a selection of termination options. With large threads suitable for external mounting and for use in two operating temperature ranges; Standard (-25 to 80°C) or Extended (-40 to 125°C).
Features:
Designed for applications requiring a robust metal housing and larger threads for external mounting
Reverse polarity, ESD and transient over-voltage protected
Wide supply voltage ranges
N and P type output configurations, capable of sinking or sourcing up to 800mA, can directly drive loads
Standard and extended temperature ranges available
Stainless steel housing with polysulfone sensing tip
Choice of terminations
High operating pressure
