Type 8311 low-cost pressure transmitter
The Bürkert Type 8311 pressure measuring device is an intelligent mini transmitter/switch that features an extra-large localised display to switch alarms and establish a monitoring system or an On/Off control loop. Boasting a range of pressure settings and an optional relay for switching higher loads, this compact Bürkert pressure transmitter is ideally suited to OEM applications.

Multi-functional OEM pressure transmitter
The Bürkert 8311 is an OEM pressure transmitter that delivers indication, monitoring, transmitting and continuous or On/Off control in one device. Available in either switch or transmitter versions, the Type 8311 features a large display with a three-key keypad for programming switch points, as well as a 10-segment bar graph that provides easy monitoring of the calibrated range.
The Type 8311 digital pressure transmitter and pressure switch also displays a wide range of units as standard. As well as bar, it also provides millibar, head of mercury and head of water readings.
“If you’re an OEM manufacturer of equipment and you search Google for pressure transmitters you generally tend to get the very ‘blind’ versions that have no display and no parameterisation,” says Greg Wainhouse, Water Field Segment Manager at Bürkert.
“Furthermore, if you search for pressure transmitters with a display you will be presented with very big, heavy duty pressure transmitters. This prices a lot of customers out of the market. The Bürkert 8311 digital pressure transmitter is a good solution that fills that gap in the market,” he adds.
Two major advantages of the Bürkert 8311 are its inbuilt display and the fact that Bürkert provides a cradle to grave solution. “The Type 8311 is a simple pressure transmitter with a display that is fully supported by Bürkert,” says Greg. Which is far preferable to a two-part system involving a ‘blind’ transmitter and a retrofitted, localised display.
“There are very few competitors offering an OEM product with a display,” continues Greg. “We’ve got this very easy to use display system that we’ve developed ourselves and have been able to deploy across a range of instruments extremely effectively.”
Greg asserts that while competitors might have expertise in developing pressure transmitters, they may not necessarily have the pre-requisite knowledge of pressure sensors to supplement this. Bürkert is proficient in both areas. “The whole thing is supported by Bürkert,” he says, before adding: “It’s therefore great for OEM applications.”
Bürkert pressure transmitter applications
The Bürkert 8311 pressure transmitter is suitable for any applications requiring a variable pressure configuration. It also provides a cost-effective solution for smaller scale applications that do not necessarily require a full-blown PLC but instead require a very small control loop. This is made possible thanks to the Type 8311’s user-friendly backlit display.
This innovative Bürkert pressure transmitter performs exceptionally in a wide range of applications, such as pressure control loops, control of air and liquids, machine presses, filtration skids, airline control and gas blanketing control.
“We sell quite a few Bürkert 8311 transmitters to the water skid market because it gives customers the ability to view the pressure locally,” continues Greg. “If they want to execute any particular control commands, they don’t have to rely on a large PLC, they can do it just with the on/off control unit instead.”
