Description
The PRKA is a pressure sensor with OLED display: besides pressure value and unit it shows the percentage of range and both switching states. The standard version measures with a silicon sensor up to 1000 bar; there are also flush versions with ceramic or oil-filled metal diaphragm up to 100 bar, also with sanitary clamp.
