Pressure switches of the HCD series are suitable	connection piece G 1/8” (remove sealing cham-
for neutral and non-aggressive gases. They can	ber). For differential pressure detection the high
be used for monitoring overpressure and differ-	pressure is applied to the lower connection
ential pressure. For overpressure detection the	piece (G 1/4”) and the low pressure side to the
pressure side is connected to the lower connec-	upper connection piece (G 1/8”). A pressure
tion piece G 1/4”; for vacuum detection the	measurement connector (9 mm ø) is available for
pressure side is connected to the upper	accurate setpoint adjustment.

Technical data

Pressure connection

Pressure connection for overpressure: G 1/4” internal thread.

For vacuum and differential pressure: G 1/8” internal thread.

Switch housing

Diecast aluminium.

Medium temperature

–15 to +60 °C.

Maximum working pressure

See Product Summary

Mounting position

Horizontal with connection pieces pointing downwards.

Type of protection IP 40 according to DIN 40050.

Mounting

Either directly on pipe or with mounting bracket (supplied) on a vertical surface.

Setting the switching point

Remove the cover and turn the setting spindle marked +/– in the corresponding direction. The scale shows only guideline values. For accurate setpoint adjustment it is necessary to use a pressure gauge which can be attached to the measuring point (9 mm ø pressure measurement connector).

Switching function Single pole switching.

Electrical connection

Switching capacity

2 A/220–240 VAC (inductive load)

10 A/220–240 V AC (resistive load)

Cable entry Pg 13.5

Tested according to Gas Appliance Directive 90/396/EEC, DVGW reg. no. E 3085/2.
