Sensortechnics’ new submersible pressure transmitter HYD offers high-precision hydrostatic level measurement for pressure ranges from 1 metre water column (100 mbar). The HYD level probe features a compact and rugged stainless steel housing, incorporating a flush mounted laser-welded diaphragm suitable for use with viscous media. The HYD series achieves an excellent long-term stability of <±0,1 %FSS/year. The HYD transmitters are temperature compensated and provide a 4...20 mA output signal. A special cable with an integrated vent tube allows a true reference pressure to the sensor element and thus eliminates errors due to barometric pressure changes. An intrinsically safe version of the transmitter according to ATEX II 1G (EEx ia IIc T4) is available for use in hazardous areas. Custom specific calibrations and different cable lengths are available on request. Because of its excellent media compatibility, HYD transmitters can be used for a wide range of level control applications. Examples are the level measurement in waterworks, deep wells, tanks, reservoirs, etc.
