Description
The PMKA is a digital pressure controller in a stainless steel gauge housing: it measures, displays and switches via four relays – with an additional 4 … 20 mA standard signal. At the front sits a pressure sensor with oil-filled isolating diaphragm; the four switching points are set directly on the device. Typical uses are hydropower and water supply, chemicals, mechanical engineering and hydraulics.
