PHT120 Miniature Pressure Sensor

Description

Operating from –40 up to +175°C, the PHT120 Miniature Pressure Sensor series is dedicated to high temperature pressure measurements. With all stainless steel wetted parts, it is compatible with most media, including corrosive fluids used in automotive, aerospace and energy industries. Equipped with the premium thin film technology developed by EFE, its performances and stability over wide temperature range are excellent. The PHT120 is available with unamplified output (mV/V), compensated in temperature to deliver the best accuracy. Amplified output (Vdc) is also standard, thanks to a high performance and rugged built-in electronic module.

EFE has been developing and manufacturing a complete range of pressure sensors since 1973. They have designed their proprietary advanced sensing technologies and created a unique range of high performance and miniature pressure transducers.

With over 35 years of experience, we have developed a unique range of miniature and sub-miniature pressure transducers. This complete range includes:
– Low pressure (from 100 mbar), high pressure (up to 3000 bar) and negative/positive pressure ranges (from –1 bar).
– Unamplified sensors,
– Transducers with analogue or digital built-in electronics
– Standard or high accuracy with digitally corrected transducers offering ultimate total error band including all errors in the compensated temperature range (0.1% fs).
– Large temperature capability: from –60°C to 260°C for unamplified sensors and –55°C to +175°C for amplified transducers.
– High dynamic capability with semi-flush diaphragms
– High performance built-in electronics adapted to on-board applications (8-16V or 8-30V power supply), high bandwidth capability (up to 5 or 10 kHz), low noise, low consumption (<10 mA) and related protection.
– All stainless steel, titanium or inconel construction allowing compatibility with corrosive media
– Robust construction proven in the harshest environments

Applications where space is limited and weight critical : gear box & engine development, satellite, missile, aerospace, motorsport.
