The "ComPRESS" series are submersible level transmitters with a cable or SS tube extensin, to measure the level in waer workds, deep wells, undergorund tanks, concrete bunkers, etc.
The "ComPRESS" transmitters are avalilable as fixed range (type SL300) units, or with adjustable zero and span.
All transmitters are fully temperature compensated, and are equiped with strong flush mounted diaphragms who are laserwelded, this results in a perfect ong term stability.
