Description
This tri-clamp sensor can be used to directly measure liquid volume level in a vessel (such as a kettle) via hydro-static pressure sensing. It has a 1.5″ Tri-Clamp Mount and a flush SS diaphragm which enables simple cleaning and functions in sanitary applications. It can be mounted vertically (bottom mount) or horizontally (side mount). The sensor can measure liquids up to boiling temperatures and contains an embedded radiator to keep the sensor module cool. It comes with a pre-wired DIN connector and ~15 ft. cable. The sensor output is a 0-5 VDC proportional analog voltage which can be wired directly to a BruControl interface.
The sensors measure liquid column above the sensor. The 50 millibar version (PSF-20-5) can measure approximately 18 in. / 455 mm above the sensor. The 100 millibar version (PSF-20-10) can measure approximately 36 in. / 910 mm above the sensor. The volume which is measured is dependent on the vessel diameter. To calculate the volume and calibrate the sensor, use the Sensor Calibration Tool.
