Description
The DS-221-2-11S uses a Bourdon tube element with fixed deadband and covers 50 to 1000 psig. The Dwyer DS series switches listed here are Bourdon tube pressure switches with a fixed deadband. Process pressure flexes the Bourdon tube, which operates the electrical switch when the pressure reaches the setpoint. Bourdon tube sensing handles high pressure ranges, so these switches suit hydraulic power units, compressors, and high pressure process lines where an alarm or shutdown must be triggered at a set pressure.
