LHT11 Hydrostatic Level Transmitter

Brand: Intempco Controls, Inc

Model LHT11 submersible hydrostatic level transmitter is designed for applications where high reliability, long term stability and accuracy are required.

It is easy to install and is ideally suited for protecting submersible pumps in deep wells.

The level metering is based on the measuring of the pressure difference between the hydrostatic pressure of the liquid head over the diaphragm and the actual atmospheric pressure.

This pressure difference is converted into 4-20 mA current in the 2-wire version and 0-5 Vdc or 0-10 Vdc voltage in the 3-wire version.

The LHT11 consists of a stainless steel measuring cell, transmitter, stainless steel probe and a special breathing cable.

Stainless flush diaphragm is protected by use of a stainless protection cap. Easy installation and wiring is ensured by the use of the complete set of accessories.

For outdoor measurements the application of over voltage protection is suggested.
