Pressure Switch
[Type C72/C]
(intrinsically safe)
The intrinsically safe C72/C pressure switch monitors the pressure from fluids and gases in explosive environments. To that end the upper and lower switching points can be separately adjusted. The inner threads of the pipe connection measures G 3/8».
