Industrial Pressure Sensors for Harsh Environments


Telford UK - Gefran launches its new TPFADA series industrial pressure sensors for use with particularly dense or high-viscosity fluids such as oils, rubbers, pulps, and chemicals where traditional transducers with an internal diaphragm are unsuitable. Reliability in the harshest environments is ensured by an extra-thick diaphragm: the TPFADA series is based on the extensimetric measurement principle with bonded strain gauge on stainless steel (INOX 17-4 PH).


The latest-generation electronics offers a wide choice of current and voltage signal outputs, and the innovative “Digital Autozero & Span” option provides quick and easy automatic zero setting after installation, with a touch of the magnetic pen supplied with the transducer. The extra-thick diaphragm TPFADA series covers pressure measurement from 10 to 1000 bar in a wide range of models with a choice of electrical connection and threaded mounting shafts. The compact sensor is suitable for use with abrasive media and work temperatures up to 120°C. Gefran is the only company to offer the Digital Autozero & Span (no trimmer) option, which includes generation of the calibration signal (80% FS).


Main benefits:


- simplicity and reliability

- sturdy steel diaphragm (with thickness up to 2.2 mm)

- digital zero & span setting

- compact mechanical dimensions (Ш26.5 mm)

- easy installation thanks to threaded shaft connection
