5.4 Permissible ambient and operating temperatures
When mounting the pressure gauge it must be ensured that, taking
into consideration the influence of convection and heat radiation,
EN
no deviation above or below the permissible ambient and media
temperatures can occur. The influence of temperature on the indica-
tion accuracy must be observed.
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation.
5.5 Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration.
5.6 Commissioning
During the commissioning process pressure surges must be avoided
at all costs.
