Accurate pressure measurement
Equipped with easy-to-read, 80 or 100 mm-diameter dials, these Alfa Laval pressure gauges are mechanical pressure-measuring indicators that cover a range of between -1 and 40 bar and process temperatures up to 200°C. A built-in volume compensator and a relief plug contribute to measurement accuracy.
Robust pressure gauge design
Manufactured from robust, resilient materials, standard Alfa Laval liquid-filled pressure gauges are cased in 304 stainless steel housing. All product-wetted parts as well as the clamp connection and diaphragm are made of acid-resistant, 316 stainless steel.
Operating principle
Alfa Laval pressure gauges measure pressure by means of the Bourdon principle. Silicone oil is used as the medium to convert the pressure applied to the diaphragm to a Bourdon tube. The Bourdon tube is in mechanical contact with the indicating needle and turns the needle on the pressure dial of the gauge to present the pressure measurement.
Options
- Electropolished surface finish
- Calibration-, 3A-, and 3.1 certificate
- U.S. Food and Drug Administration Declaration of Conformity
- Bar / KPa / Psi scale
Application
The Alfa Laval pressure gauge is designed to fulfil the demands of pressure gauges in Sanitary and pharmaceutical production. It issuitable as a local indicator in filtration systems, pump system pressure vessels etc.
Features: Wetted parts in acid-proof, stainless steel. Measuring range -1 to 60 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 316L).
