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 pressure gauge is designed for measuring very low pressures 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

■

Nominal size 110 mm

■

The instruments measure the pressure by means of separating

diaphragms (silicone)

■

The measuring characteristics are in accordance with the EN 837-3

standard and ventilation and air conditioning (VAC) regulations

Scope of delivery

Cross-check the scope of delivery with the delivery note.

5. Transport, packaging ... / 6. Commissioning, operation

5. Transport, packaging and storage

5.1 Transport

Check the pressure gauge for any damage that may have been caused

by transport. Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during trans-

port (e.g. change in installation site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage

Storage temperature: -30 ... +80 °C

Protect the instruments from moisture and dust.

6. Commissioning, operation

Installation and mechanical connection

In accordance with the general technical regulations for pressure

gauges (e.g. EN 837-2 "Selection and installation recommendations for

pressure gauges").

■

Process connection back mount (BM)

■

Protect measuring instruments from contamination, high temperature

changes and vibrations

■

air2guide Eco dierential pressure gauges are calibrated in vertical

position and should be installed in the same position to avoid loss of

class accuracy. If a dierent installation position is required please

specify when ordering. Gauges with high pressure ranges can

be installed in dierent non-vertical mounting position, by simply

adjusting the zero point.

6. Commissioning, operation

Panel mounting

1. Fasten the mounting ring using the supplied

three screws.

2. Insert the measuring instrument into the

mounting ring.

3.Turn the measuring instrument clockwise

or anti-clockwise, until an exactly horizontal

positioning is reached.

6. Commissioning, operation

Commissioning

■

During the commissioning process pressure surges must be avoided

at all costs

■

Install the pressure connection according to the symbols

⊕ high pressure ⊖ low pressure

■

Use the pressure gauge only if the diaphragm is undamaged and if it

is in perfect condition with regard to safety.

Option screw built-in variant

After tting the measuring element into the case

it can be moved in a clockwise and counter-

clockwise direction respectively for 15 angular

degrees in order to ensure precise horizontal

positioning of the instrument.
