Installation

 Do not damage the diaphragm; scratches on the diaphragm (e.g.

from sharp-edged objects) are the main causes of corrosion

 For sealing, choose appropriate seals

 For ange mounting, use a seal with a suciently large internal

diameter and centre it; contact with the diaphragm leads to measur-

ing errors

 When using soft or PTFE seals, observe the instructions of the seal

manufacturer, particularly with regards to tightening torque and load

cycles

 For installation, in accordance with the tting and ange standards,

the appropriate fastenings, such as screws and nuts, must be used

Permissible ambient and operating temperatures

When mounting the pressure gauge it must be ensured that, taking

into consideration the inuence of convection and heat radiation,

no deviation above or below the permissible ambient and medium

temperatures can occur. The inuence of temperature on the indication

accuracy must be observed.

 In order to avoid any additional heating, the instruments must not be

exposed to direct solar irradiation while in operation!

Permissible vibration load at the installation site

 The instruments should always be installed in locations free from

vibration

Commissioning

During the commissioning process pressure surges must be avoided

at all costs.
