Ambient and Media Temperature For pressure gauges – A-series – 1-261 GB

Sheet No.: 1-261 GB

*) The average value of the maximum ambient temperature and the media temperature
must not exceed the maximum ambient temperature.

Example: at a media temperature of 100°C the ambient temperature must not exceed
20°C, when glycerine filled.

(Media temperature + Ambient temperature)/2  ≤ (maximum ambient temperature (100° C+20°C))/2  = 60°C

Temperature compensation

The unique temperature compensation system ensures an accurate display. Under con-ditions where the ambient temperature may vary, automatic compensation is made for  temperature changes of up to 60°C.

The temperature compensation system also functions as a blow-out mechanism. Should the measuring system explode due to excess pressure, the temperature compensation system is pushed out the back of the instrument.
