Stable, accurate temperature measurement
Alfa Laval thermometers are sturdy mechanical temperature gauges that provide accurate measurement of local temperature for a broad range of hygienic processes. Temperature indication is easy to read on the 80 or 100 mm-diameter dial. A built-in bimetallic coil automatically compensates for any effect on the reading caused by changes of the ambient temperature.
Reliable thermometer design
Manufactured from robust, corrosion-resistant materials, these thermometers feature 304 stainless steel casing and a 316 stainless steel clamp connection and sensor tube.
Alfa Laval thermometers come as standard with liquid-filled housing. An inert gas that is completely neutral to the environment is used as the filling medium for the sensor tube, making the thermometers suitable for hygienic processes.

Application
The Alfa Laval thermometer is designed to fulfil the demands of local temperature indication in sanitary and pharmaceutical production. Main features are: Hygenic connection and robust design, high resistance to corrosion, damp, vibrations and wear. Accurate and long term measurement stability with quick response time. Due to their first class accuracy and long term measurement stability, no yearly calibration is needed. Available in two sizes.
Standard range
Our standard range comes with a liquid-filled housing. It includes an 80 or 100 mm diameter dial and built-in temperature compensator. The housing is made of stainless steel (AISI 304) and the clamp connection and sensor tube is made of stainless steel (AISI 316). As an option, it can be delivered electropolished and with 3A, 3.1 or calibration certificate.

Working principle
The function is based on expansion of the filling medium in the closed sensor. The change of pressure actuates the spiral spring driving the dial movement. A built-in bimetallic coil compensates automatically for the effect on the reading caused by change of the ambient temperature. The filling media is an inert gas which is 100% neutral to the environment. This makes the thermometer ideal for use in food and pharmaceutical industries.
