Flush-Diaphragm Pressure Sensors The 664F(b) pressure sensor which provides outstanding thermal stability and high accuracy is based on the BCM high-quality metal foil strain gauge. The sensor features all welded structure so there is no O-ring seal inside the sensor body. As this model employs flush-diaphragm structure, the 664F(b) is suitable for pressure measurement of viscous fluids or fluids with media containing solids. The sensor has its process connection and electronics housing connection with threads, and the entire sensor • rugged and fully welded structure • reliable metal foil strain gauge technology • compensated temperature range: -20 ~ +85 °C • excited by either current or voltage • industrial controls • hydraulic systems • food industry • process control systems Environmental Specifications • position effect: < 0.1% of zero offset shift • vibration effect: no change at 10 g (RMS), Electrical Interface excitation - (black) signal - (white) BCM SENSOR TECHNOLOGIES BVBA Industriepark Zone 4, Brechtsebaan 2 Tel.: +32-3-238 6469 website: www.bcmsensor.com B-2900 Schoten - Antwerpen, BELGIUM Fax: +32-3-238 4171 email: sales
