Pressure gauges for sanitary use
Pressure gauges
Application
 The Alfa Laval pressure gauge is designed to fulfil the demands of pressure gauges in Sanitary and pharmaceutical production. It is suitable as a local indicator in filtration systems, pump system pressure vessels etc.
Features:
Wetted parts in acid-proof, stainless steel
Measuring range -1 to 40 bar
Process temperature up to 200°C
Working principle
The pressure gauge working principle is build on the Bourdon principle where pressure applied on the diaphragm is transmitted via silicone oil to a bourdon tube which is in mechanical contact with the dial, and thus indicates the pressure applied on the diaphragm
Standard range
Our standard range is supplied with a liquid-filled housing. It includes a 100 mm dial diameter and a built-in volume compensator and relief plug. The housing is made of stainless steel (AISI 304) and the clamp connection and pressure sensor are made of stainless steel (AISI 316).
