High precision pressure measurement
Alfa Laval pressure transmitters are accurate measuring devices that indicate pressure in hygiene process equipment and systems. These IP67 protected pressure transmitters are ideal for use in the brewery, food and beverage, personal care and pharmaceutical industries.
Fast, accurate performance
Engineered for long-term stability and high overload capacity, Alfa Laval pressure transmitters maintain accurate performance and have a response time of <10 ms. These pressure transmitters provide a <=0.35% FS accuracy for nominal pressure lower than 0.4 bar and a <=0.5% FS accuracy for nominal pressure greater than or equal to 0.4 bar. An optional version that provides a <=0.1% FS accuracy is available for nominal pressure lower than 0.4 bar.
Pressure transmitter range
Standard Alfa Laval pressure transmitters cover 10 different measuring ranges with pressures between -1 and 40 and integrated temperature compensation from 0 to +70°C (+32 to 158°F).
These pressure measurement devices are suitable for use with all media that are compatible with AISI 316L stainless steel and feature 4-20 mA output signals (two- or three-wire). The hygienic process connection is flushable and filled with FDA-approved silicone oil. The pressure transmitter can be delivered either with clamps DN 38 (ISO2852) / DN 40 (DIN32676) or with clamps DN 50 (ISO2852) / DN 51 (DIN32676).
To handle high media temperatures up to 300°C (572°F), an optional cooling element is available. The Alfa Laval pressure transmitter is also available in an ATEX-approved version that is suitable for use in potentially explosive areas (zone 0 or 1).
Operating principle
The Alfa Laval pressure transmitter is an analogue pressure sensor that uses the piezoresistive effect to measure pressure. Made of stainless steel, the piezoresistive pressure transmitter provides pressure measurement with an accuracy of up to 0.1 % FSO (IEC 60770), thanks to its small temperature effect and excellent linearity.
Application
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. The main features are:
- 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.

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 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 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).

Accurate, reliable pressure indication
The Alfa Laval Electronical pressure gauge provides accurate and reliable pressure measurement withelectrical output capabilities.It fulfils the demands for pressure indication in hygienic systems for the food, beverage, brewery and pharmaceutical industries.
These electronical pressure gauges come equipped with a DN38 connection, a turnable scale to enable alternative mounting (350°) and adjustable pressure switch. Other features include analogue output (4-20 mA) and integrated push buttons and digital display for easy setup.
Analogue and digital displays
Alfa Laval electronical pressure gauges offer the distinct advantages of displaying current system pressure in both analogue and digital formats. The analogue display indicates pressure in bar and kPa using a pointer and circular scale.
The digital display features unique LED indicator embedded in the outer circumference of the scale for quick, easy and precise readings for fast decision-making purposes by providing indication of:
- Current system pressure
- Parameters and parameter values
- Set point and reset point
- Trends, including rising pressure and falling pressure
- Lag with maximum value or minimum value
- Pressure pulsation and pressure peaks
Standard and custom output
Alfa Laval electronical pressure gauge come with two output signals with standard factory settings. However, output can be tailored to customer requirements using the two easy-to-use touch buttons and the digital display, which enables the selection, setting and verification of parameter values in order to generate the two custom output signals. This makes the electronic pressure gauge an excellent choice for straightforward pressure monitoring as well as pressure switch and pump monitoring applications.
Operating principle
The Alfa Laval electronical pressure gauge is based on an internal ceramic pressure sensor, which together with the metal diaphragm, ensures a proper hygienic process connection.
In order to offer the many advanced setup possibilities and the intelligent scale, the Alfa Laval electronical pressure gauge uses an advanced microprocessor. The microprocessor controls the embedded LED indicator in the scale, the output signals and as well the movement of the physical dial.
The turn-able dial is approved for IP69K, which ensures maximum tightness between the dial and the housing, which ensures tight closure for the service lifetime of the gauge.
