Gefran Sensors

POSITION SENSORS

Linear and angular position transducers detect the position of mechanical parts in motion.

Gefran manufactures a wide and unique range of models, using consolidated and new technologies, including: the potentiometric technology, magnetostriction, Hall effect and MEMS technology.

LINEAR TWIIST

Fully sealed, solid and compact sensor. Suitable for industrial applications and mobile hydraulics.

POTENTIOMETERS

Linear and rotary potentiometers. Reduced dimensions, absolute voltage dividers.

ROTARY

Available in single-turn with Hall effect version. With analogue and fieldbus outputs.

MAGNETOSTRICTIVES

Available in mechanical forms with profile and rod. With analogue, digital and fieldbus signal outputs.

INCLINOMETERS

High precision measurement of inclinations from ±10° to ±180°. With analogue and redundant fieldbus outputs.

LINEAR BY WIRE

Suitable for measurement from 1500mm to 8300mm. With analogue and redundant fieldbus outputs.

PRESSURE SENSORS

Gerfan’s industrial pressure transducers and transmitters measure the pressure of fluids(liquid or gas)in industrial and mobile hydraulics markets

Three main technologies are used by Gefran when manufacturing pressure sensors: thick film on steel, piezoresistive on silicon on sapphire and bonded strain gauge. Reliable, accurate and flexible technologies in terms of application and performance. Outside of the traditional technology with internal measuring chamber, with optional pressure snubber against pressure peaks, Gefran also provides flush diaphgram pressure sensors with direct mechanical measurement using a solid 17-4 PH stainless steel membrane. These transducers are specifically designed for measuring pressures of highly dense fluids or substances with high viscosity like oils, rubbers, chemical products, etc. Such applications would make measurements difficult from sensors with internal measuring chamber. Additionally, our product range includes melt transmitters for high temperatures and pressure sensor with ATEX certification, which are ideal for applications in potentially explosive areas. The SIL2 Machine Safety certification, PLd, confirms its reliability but also satisfies the current Machine Safety directives. EU certifications such as CE, CuLUs, PESO, IECEx FM and PAC further complete the set.

INDUSTRIAL

Fluid and gas pressure measurement. Models available for special and high precision applications.

MELT - HIGH TEMPERATURE

Media pressure detection with temperatures up to 538°C. Available in various mechanical versions.

TEMPERATURE SENSORS

Thermocouples and thermoresistances meets the temperatures measure temperatures in the industrial sector.

Gefran provides a wide range of thermocouples and thermistors, covering a wide temperature range from -40° to 1600°. Our set of thermocouples and thermistors is available in various mechanical designs, dimensional and precision, satisfying different needs of application in numerous industrial sectors.
