Hygienic Pressure Measurement
Alfa Laval Pressure TransmittersApplication
 The Alfa Laval pressure transmitter is designed to fulfil the demands of pressure measurement in sanitary and pharmaceutical production.
It is suitable in filtration systems, pump systems, pressure vessels, valve matrixes etc.
Main features:
- Long Term stability
- High overload capacity
- Good accuracy, 0.35 % of FS
- 4-20 mA output (3 or 2 wire)
Standard range
The Alfa Laval pressure transmitter range can be used with all media that are compatible with stainless steel W 1.4435 (AISI 316L). For usage with high media temperature a cooling element can be added thus media temperatures up to 300° C can be achieved.
The flushable process connection is oil filled with FDA approved Oil and delivered in either Clamp DN 38 (ISO2852) / Clamp DN 40 (DIN32676) or Clamp DN 50 (ISO2852) / Clamp DN 51 (DIN32676).
Optionally the Alfa Laval Pressure transmitter is suited for explosive area (zone 0 or 1).
Working principle
The Alfa Laval pressure transmitter builds on a piezoresistive stainless steel sensor, which features small thermal effect and excellent linearity, making it possible to meet accuracy demands up to 0.1 % FSO (IEC 60770).
