Products - Thick film technology

Thick film technology

Huba pressure transmitters are electrical pressure transmitters for the precise measurement of relative and absolute pressure - reliable, long-term stable and versatile.

50 mbar to 1,050 bar

Pressure sensors for industrial applications

Thick-film technology is at the heart of our industrial pressure sensors. It combines printed measuring bridges on ceramic and stainless steel diaphragms to create media-resistant and robust measuring cells for recording pressure, level and flow rate. In conjunction with the appropriate signal processing, this results in precise, long-term stable and economical sensors for a wide range of pressure tasks.

Advantages of thick-film technology

Media-resistant measuring cells - not oil-backfilled
High overload and burst resistance as well as long-term stable measured values
Excellent shock and vibration resistance
High temperature stability

Functional principle of thick-film sensors

Applying pressure deforms the ceramic membrane minimally elastically.
The deformation changes the value of the applied thick-film resistors.
Wheatstone bridge converts the change in resistance into a raw electrical signal.
An integrated signal path (typically ASIC) linearises, Temperature-compensates and amplifies the signal.

Huba-specific expertise

Huba Control develops and produces in-house - from thick-film production, glass soldering processes and laser trimming to final calibration and 100% final testing. This vertical integration ensures high availability, consistent quality and customised OEM solutions - and makes Huba the specialist for precise, robust pressure sensors.
