HomePressure Instruments

Powerful instruments for process pressure, differential pressure, level and flow.

Whether pressure, level or flow, today pressure measurement technology is often used for measuring liquids, pastes and gases. With a wide range of sensor technology Endress+Hauser offer instruments with perfect fit for any kind of application.

Competence in pressure measurement

The broad range of products makes it easy to find the ideal solution. No product is suited to all application areas. Therefore measuring systems must work reliably under the conditions of a particular application while meeting economic expectations.

Absolute & Gauge Pressure Measurement

Pressure transducers for continuous measurement or pressure switches in liquids

Absolute and gauge pressure continuous measurement or pressure switches provide the safe measurement of liquids and gases in various applications. Cerabar sensors and Ceraphant switches monitor reliably the level in food applications. The devices have various hygienic approvals. Also in the process industry with SIL and explosion protection certificates there is reliable measurement guaranteed. Check out the broad range of Cerabar and Ceraphant devices and click on the button below.

Absolute and gauge pressure measurement with ceramic or silicon cell or diaphragm seal offer the perfect fit for various applications in the process and hygienic industries. With the right sensor technology and fit for purpose devices Endress+Hauser offers pressure transducers with quick setup or even just plug & play which allows simple commissioning, reduces costs and saves time – be it a pressure switch or a pressure transmitter.


Silicon cell: For process pressures up to 700bar (10,500psi), small flush-mount process connections, guaranteed overload resistance, minimal thermal effects
Diaphragm seal: Variety of special materials and process connections, process temperatures from-70 up to +400°C (-94 to +752°F).
Pressure switch: Function check and on-site information with LEDs and digital display, operation and visualization also possible via PC, stainless steel housing and lasered nameplate

Differential Pressure

Continuous level, flow and differential pressure measurement

Differential pressure transmitters with piezoresistive pressure sensors and welded metallic membrane or electronic dp or diaphragm seal is used mostly in the process industry. Deltabar offers continuous level measurement in liquids as well as volume or mass flow measurement using primary elements. It is also possible to do filter monitoring with the differential pressure transmitter. Check out the broad range of Deltabar devices and click on the button below.

Pressure Gauge Products

Beside the devices with silicon or diaphragm seal for differential pressure, level, dp flow measurement, Deltabar electronic dp is a differential pressure system combining two sensor modules and one transmitter. In level applications, the high pressure sensor (HP) measures the hydrostatic pressure. The low pressure sensor (LP) measures the head pressure. The level or differential pressure is calculated in the transmitter using these two digital values.

Differential pressure measurement: Measuring Principle

Silicon cell: The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Diaphragm seal: The operating pressure acts on the process isolating diaphragm of the diaphragm seal and is transferred to the process isolating diaphragm of the sensor by a fill fluid.


Universal dp transmitter for flow, level or filter applications
With diaphragm seal process temperatures from -70 up to +400°C (-94 to +752°F)
The electronic differential pressure system eliminates traditional mechanical issues resulting in greater process availability and reliability. Also safety risks are minimized with the electronic dp system architecture and design
