Application 

TEMPRESS thermometer, type A7801, is a qual­ity instrument for use in food and beverage or phar­maceutical applications, where there is a need for reliable and easy-to-read temperature gauges.

The thermometer is in a liquid filled 63 mm case with either a bottom or rear immersion tube, and it is made of totally acid proof stainless steel, AISI 316. The immersion tube is smooth and the thermo­meter is normaly mounted with a compression pocket for welding or with clamp. For auxiliary proc­esses a screwed compression gland or pocket can be used (see data sheet 3-15).

The instrument has a built-in bimetallic compen­sation. This permits a very high ambient tempera­ture (up to 100°C) which means it can be mounted directly onto e.g. steam pipes.

A7801 is a gas filled expansion thermometer. The particular advantages of this principle are, long-term stability, fast reaction time and good accuracy.
