A new generation of pressure gauge (PG) type manometers is now equipped with modern display units featuring illuminated LED markings to provide a quick overview of measured values. In addition to the various setting options for the display unit, IO-Link also offers advantages such as easy commissioning, quick sensor replacement and remote access options.

ifm highlights the further development of its analogue display PG type pressure sensors by digitalising the sensors and expanding visualisation options. The redesigned display unit now offers a quick overview of the previously defined measuring ranges and limit values through a ring of coloured LEDs. Instead of manually applying markings to the display housing, the minimum, middle and maximum ranges can now be visualised using different coloured LEDs. In addition, IO-Link allows the desired measuring ranges to be quickly defined and adapted to each application. The bright LEDs enable the user to view the pointer from a distance, to assess whether it is in the green area or close to the limit.

Process values and additional information are continuously transmitted using IO-Link technology and, because data is transmitted in a purely digital form based on a 24 V signal, it is conversion and loss-free. The PG pressure sensors boast a measuring range from -1 bar to 400 bar. As with previous models, the sensors are equipped with a robust ceramic measuring cell. The measuring cell has a diagnostic function that displays the cell’s status, helping to ensure safety in critical applications.

The electronic manometers are used in the food industry and other industrial environments. To meet the prevailing requirements, two device variants have been developed with differing approvals and technical properties. For example, the device variant for food applications is permanently temperature-resistant up to 150 °C and will compensate for the dynamic temperature fluctuations that can occur in cleaning cycles.
