WIKA operating instructions dierential pressure gauge models 712.15.100, 732.15.100

1. Safety ... 3. Installation

2. General information

These operating instructions are based upon the following:

 EN 837-2: Selection and installation recommendations for pressure gauges

 Data sheet PM 07.29: Dierential pressure gauges models 712.15.100, 732.15.100

 Data sheet PM 02.01, PM 02.02: Bourdon tube pressure gauges

3. Installation

The installation of the dierential pressure gauge should be carried out in accordance with the

installation recommendations for pressure gauges per EN 837-2 /7.

 Prior to the installation of the pressure gauge, the pipes should be thoroughly cleaned

 The pressure gauge should be installed and operated such as to avoid exposure to

vibration.

Mounting by means of - rigid tailpipe and/or

- 4 M8 threaded mounting holes incorporated in the body

 The pressure gauges should be protected against contamination and high temperature

uctuations

 The maximum permissible media/ambient temperature must not be exceeded

Fitting of the pressure connections as per the

and

symbols

higher pressure ⇒ bottom pressure (p

lower pressure ⇒ working pressure/overriding pressure (p

)

= p

+ p

(with p

= hydrostatic pressure of liquid = ρ • g • h)

1. Safety

WARNING!

Before installation, commissioning and operation, ensure that the

appropriate dierential pressure gauge has been selected in terms of

measuring range, design and specic measuring conditions.

Only work on the gauge with the voltage disconnected.

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

Only appropriately qualied skilled personnel should work on these

instruments.
