Cost effective pressure sensor
Published: 11 January 2012 - Heather Ramsden
Sensortechnics’ new SSO stainless steel pressure sensors accurately measure gage or absolute pressures in ranges from 200mbar up to 35bar. Fully welded, media isolated rugged stainless steel constructions with G 1/8 (BSP) threaded pressure ports allow for high media compatibility with corrosive liquids and gases. These devices are precision calibrated and temperature compensated and offer excellent repeatability as well as long-term stability. A fully analog compensation technique ensures a nearly unlimited pressure resolution as well as very fast response times.
The SSO sensors are based on proven piezoresistive silicon pressure sensing elements and are said to offer OEM customers an excellent price/performance ratio. The laser-trimmed compensation resistors deposited on a ceramic substrate are protected by a special coating against environmental hazards such as humidity or dirt.
Additionally, Sensortechnics can provide very fast and flexible modifications of its SSO pressure sensors to fit custom specific requirements as well as versions with amplified analog and I²C bus output.
