Mono-Block Ceramic Pressure Sensors The 301B is piesoresistive pressure sensor based on ceramics. By means of thick film technology, the bridge circuit is directly printed at the back of a ceramic pressure diaphragm. Thanks to excellent corrosion resistance, the other side of the diaphragm can be exposed to measured media without any additional protection. And this sensor is widely used in HVAC As the 301B is made from one piece of AI203 ceramics (mono-block structure), it possesses a rigid structure and can be mounted directly in a case by using an O- ring or to a metal fitting. The sensor has the standard diameter of 18mm and are temperature compensated. There are also various options of output signal available on request. • excellent corrosion resistance • various output options: 2.5mV/V, impact and vibration resistance • easy mounting • automotive industry • HAVC systems • liquid level control • process control systems • pneumatic and hydraulic controls • biomedical instrumentation 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@bc

Mono-Block Ceramic Pressure Sensors Technical Data General conditions for measurements: media temp. = 25°C ±1°C, ambient temp. = 25°C ±1°C. Notes: 1. For customized pressure ranges, consult BCM. 2. "fs" means full scale and refers the maximum working pressure or rated pressure. 3. Measured at full scale pressure. 4. Combined non-linearity, hysteresis, and repeatability. 5. Calculated as a rate of output change between 0°C and 70°C, and normalized by the output at 25°C. 6. Response time for a 0 bar to fs step change, 10% to 90% rise time of leading edge. 7. 4 contacts for millivolt output and...
