Pressure Transmitters

Types of pressure sensors

• Gauge pressure sensors: measure pressure relative to atmospheric pressure.
• Absolute pressure sensors: measure pressure relative to a perfect vacuum.
• Differential pressure sensors: measure the difference between two pressure points, for example across a filter or for flow and level measurement.
• Vacuum pressure sensors: measure pressure below atmospheric level.
• Flush diaphragm pressure sensors: have no cavity where media can collect, so they suit viscous, dirty, or hygienic media.
• Digital pressure sensors: provide a digital output and often a local display and switching outputs.

How to choose a pressure sensor

1. Pressure type: gauge, absolute, differential, or vacuum.
2. Pressure range: choose a range above your normal working pressure to leave room for spikes.
3. Output signal: 4-20 mA, 0-10 V, 0-5 V, or a digital interface, matched to your PLC or controller input.
4. Media compatibility: check that the wetted materials (such as stainless steel) suit the liquid or gas and temperature.
5. Process connection: thread type and size, such as G1/4 or NPT.
6. Accuracy and environment: required accuracy, ingress protection (IP rating), and hazardous-area approvals if needed.

To show and monitor pressure readings on site, pair your sensor with one of our panel meters.
