AM-HLT Hydrostatic Level Transducers
The AM-HLT Hydrostatic Level Transducers are simple, rugged and inexpensive level sensors with built-in 4-20 mA transmitters. The user simply places the sensor at the bottom of the water (or fluid). The sensor converts the difference between the hydrostatic pressure and atmospheric pressure to the water depth.
With an IP68 rating they are right at home in everything from potable water to activated sludge and any Class I, Div 2 environment. Wetted materials are 316 SS (titanium is optional) teflon coated diaphragm. The vent tube is kept dry with a patented vent filter. Every sensor is customized by the customer (at not additional cost) to provide a 4-20 mA output tailored to the maximum depth required.
Every sensor includes a vent filter to prevent moisture from entering the vent tube. An optional aneroid bellows permanently seals the vent tube. Optional anti-surge circuity offers lifetime-guaranteed protection from lightning strikes and power surges.
