Pressure and vacuum switch
Service units and instrumentation
Pressure and vacuum switches as well as pressure transmitters convert process pressure into electrical switching or analogue signals, enabling monitoring and control of pneumatic and hydraulic systems. The range comprises more than 400 items, mostly from Wika.
The DMU series pressure transmitters cover ranges from 0-10 bar to 0-600 bar and are available with a flush diaphragm for viscous or contaminated media. Weld-in sockets with G 1/2" and G 1" serve the process-side connection.
Pressure switches and transmitters monitor pressures on pumps, compressors and machinery and pass signals to controllers. Flush diaphragms suit highly viscous or particle-laden media that would clog conventional connections. Weld-in sockets allow tight integration into vessels and lines.
