Hydrobar Submersible Level Transmitter

Hydrobar Submersible Level Transmitter

The Hydrobar series are submersible level transmitters with a cable or SS tube extension, to measure the level in waterworks, deep wells, underground tanks, concrete bunkers, etc. The Hydrobar transmitters are available as a fixed range (type FR units), or with adjustable zero and span. All transmitters are fully temperature compensated and are equipped with strong flush mounted diaphragms who are laser welded, this results in a perfect long term stability

Principle of Operation

The Hydrobar Transmitter is always equipped with a display and 3 push buttons for easy calibration. Both the measured and the calibrated value can be read locally. A full calibration can be completed using the three push buttons or with the optional handheld terminal (HART¬), or by PC with special software.

Zero and span can be calibrated very easy, without test pressure, also in vacuum ranges. Linearisation can be made for horizontal tanks (P111). For all other adjustable points see table right. The series 2000 will as standard be delivered with 2 closed covers, so the 3 push buttons and the standard display are behind the cover. A transparent cover can be delivered as an option. In that case you can use the display as a local indicator.
