WARNING!

... indicates a potentially dangerous situation which can

result in serious injury or death if not avoided.

Information

... points out useful tips, recommendations and information

for ecient and trouble-free operation.

2. Safety

WARNING!

Before installation, commissioning and operation, ensure

that the appropriate dierential pressure switch has been

selected in terms of measuring range, design and specic

measuring conditions.

Non-observance can result in serious injury and/or damage

to the equipment.

Further important safety instructions can be found in the

individual chapters of these operating instructions.

2.1 Intended use

This dierential pressure switch is used for the monitoring of ventilators,

blowers and lters in air-conditioning and clean room applications as

well as for overpressure monitoring in clean rooms and laboratories in

dry, clean, non-aggressive gases, primarily air.

The instrument has been designed and built solely for the intended use

described here, and may only be used accordingly.

The manufacturer shall not be liable for claims of any type based on

operation contrary to the intended use.

4. Design and function

Description

Through the dierential pressure to be measured, an unopposed force

is produced on the diaphragm. This measurement force moves the

diaphragm system against the measuring range spring, and the micro

switch is activated via a switch plunger mounted on the diaphragm.

The switch point can be set on the scaled adjustment wheel.
