SCH-HCD Pressure/Differential Pressure Switch

Brand: KOBOLD Instruments, Inc.

The pressure switches of series HCD are suitable for neutral and non-aggressive gases. They can be used for monitoring overpressure, vacuum as well as differential pressure.

For detecting overpressure, connection is made on the pressure side at the lower connecting piece G 1/4" for detecting the vacuum pressure at the upper connecting piece G 1/8" (remove locking clamp).

For detecting the differential pressure, the high pressure is applied at the lower connecting piece (G 1/4") and the low pressure at the upper connecting piece (G 1/8"). For exact adjustment of the required value a pressure tapping (9 mm) is available.
