Accurate, reliable pressure indication
The Alfa Laval Electronical Pressure Gauge can correctly and reliably measure pressure and can also send electrical signals. It meets the standards for showing pressure in clean systems used in the food, drink, brewing, and drug industries.
These electrical pressure gauges have a DN38 connection, a scale that can be rotated 350° for different mounting options and a pressure switch that can be changed. It also has an analogue output (4–20 mA), built-in push buttons and a digital monitor that makes setting it up easy.
Analogue and digital displays
Alfa Laval electrical pressure gauges are great because they can show both analogue and digital versions of the current system pressure. A pointer and a circular scale on the analogue monitor show pressure in bar and kPa.
With its unique LED sign built into the outside edge of the scale, the digital display makes it easy to get quick, accurate readings that help you make quick decisions by showing:
- 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 Electrical Pressure Gauge have two output signs and are usually set to the factory defaults but the output can be changed to fit the needs of the customer by using the two simple touch buttons and the digital display. These let the parameter values be chosen, set up and checked so that the two custom output signals can be made. This makes the electrical pressure gauge a great choice for simple tasks like checking the pressure and even for tasks like checking the pressure switch and pump.

Working principle
Inside the Alfa Laval Electrical Pressure Gauge is a ceramic pressure sensor that, along with the metal diaphragm, makes sure that the process link is correct and clean. The Alfa Laval Electrical Pressure Gauge has a state-of-the-art microprocessor that allows for many advanced setup choices and the intelligent scale. The microprocessor controls the output signals, the movement of the actual dial and the LED that is built into the scale. The dial can be turned, and it is approved IP69K, which means that it has a lifetime of tight sealing between the dial and the housing.

Standard range
The standard features of the Alfa Laval Electrical Pressure Gauge encompass a DN38 connection, a rotatable scale and a digital display equipped with two touch buttons for expedited configuration. The configuration is accomplished through the utilization of two push controls and a digital display, enabling the user to customize both the digital and analogue outputs from the sensor. This versatility renders the EPG appropriate for a range of applications beyond mere pressure monitoring, including pressure switch and pump monitoring. Particularly in these applications, the distinctive LED indicator integrated into the outer circumference of the scale facilitates the localized visualization of pressure pulsations, pressure trends, and the current set point of the pressure switch.
