LT9000 Level Transmitter

The LT9000 is a continuous level transmitter that detects the level of an electrically conductive liquid in a tank or other vessel. The LT9000 can also sense the level of an interface such as oil/water.

The basic unit is made of a solid stainless steel probe, attached to an explosion proof housing. The probe is coated with a non-conductive material such as Ryton, Halar or Teflon. Inside the explosion proof housing are all calibration adjustments and sensing electronics.

The isolated 4-20 mA output signal can drive a load of up to 1000 ohms. The zero and span can be set over the entire length of the probe or any portion of the probe. The entire unit is backed by our two year warranty, 60 day money back guarantee.
