Inner-Cavity Pressure Sensors The 664F(a) 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. This model has inner-cavity structure which is suitable for pressure measurement of gases or dilute fluids. The sensor has its process connection and electronics housing connection with threads. The entire sensor body is weldable in order to give more possibility for connection ways. • 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@b

Inner-Cavity Pressure Sensors Technical Data General conditions for measurements: media temp. = 25°C ±1°C, ambient temp. = 25°C ±1°C, humidity = 50%RH ±10%RH, barometric pressure: 86-106 kPa, vibration = 0.1 g (1m/s/s) max. Notes: 1. The pressure medium should be compatible with wetted parts material and pressure diaphragm. 2. For customized pressure ranges, consult BCM. 3. "fs" refers to full scale pressure or rated pressure. 6. Calculated as a rate of output change between 25°C and 70°C, and normalized by the output at 25°C, when the sensor 7.
