Works with a Hydrostatic Level Sensor

The OleumTech® “HP1” Hydrostatic Transmitter measures water level by monitoring the pressure at the bottom point of vented top mount tanks, deep wells, water towers, rivers, and lakes. This Transmitter is equipped with one 0-5 Vdc analog input and provides high resolution 24-bit analog to digital conversion (ADC). The HP1 Transmitter can supply up to 9.5 Vdc to the connected submersible pressure sensor. This ultra-low-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life.

Reliable, Scalable and Safe

The field-proven wireless sensor node communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement. The OleumTech Wireless Transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark, and can be serviced without being removed from a process.
