Description
The PMKB is a digital pressure switch in a stainless steel housing: it displays the pressure and switches via one or two relays – for pressure protection, constant pressure control and plant monitoring. The silicon sensor behind a 316L isolating diaphragm measures water, air, oil and hydraulic oil as well as other media that do not attack stainless steel.
