Film Alumina Capacitive Pressure Sensor Ceramic / Ceramic Sensor Substrate
1. Description:
Pressure sensors are used to monitor tank level in process tanks. Often, these sensors are fitted diaphragm seals which are fragile and easily damaged in the cleaning process when hit directly by spray balls or when mechanically cleaned. What if you didn’t have to worry about damaging metal diaphragms or fill fluid leaking into your process?The direct process measurement via the PM’s capacitive-ceramic technology offers an accurate solution in a robust package.
