Level Sensors for Liquid Level Measuring or Monitoring

To meet requirements of liquid level measuring or monitoring, BCM SENSOR has utilized two technologies to manufacture liquid level sensors – one is based on hydrostatic or static pressure measurement (LV36 series) of  ranges from 0~1m to 1~200m of water column, and the other is of capacitive technology (LV66 series) to measure fuel/oil level. LV36 Submersible Hydrostatic Level Sensors are widely used in many industries. In application the LV36 level sensor is submerged in liquid to measure the liquid level. Read More...

Piezoresistive Gauge Pressure Sensors of 500G via Glass-bonding and 330B through Thick-film Process

Model 500G Gauge Pressure Sensors are developed by using SE206 silicon strain gauge chips through glass-sintering-bond process. The 500G pressure sensor can work with high working pressures (up to 5000bar), possess high output sensitivity (up to 15mV/V), high measurement accuracy (better than 0.35%fs), and high stability and no creep effect.   Because its sensor body is made from a mono-block of 316 stainless steel, the 500G pressure sensors possess high resistance to chemical corrosion. As a result of the mono-block sensor, Read More...

Metal Capacitive Differential Pressure Sensors and Transducers

Targeting the measurement (down to 0.016bar) of low differential pressure with high static pressure (up to 320bar), BCM SENSOR has developed metal capacitive differential pressure sensors (model 115C) and transducers (model 315M). The 115C sensor is in fact a differential capacitance system, which is composed of two stationary capacitance plates and in between there is a movable diaphragm as the third capacitance plate. These three plates form the so-called differential capacitance system of two capacitors. When two pressures are introduced Read More...

Ceramic Pressure Sensors and Oil-Filled Pressure Sensors

BCM SENSOR has been manufacturing and supplying high quality ceramic pressure sensors (model 301B) and oil-filled pressure sensors (model 101B). These two series pressure sensors are of piezoresistive working principle and cover wide measuring ranges from 0~0.1bar to 0~1000bar. They are used not only for mass production of pressure transmitters but also being integrated in systems to measure or monitor the system pressure. These two series pressure sensors feature different pros and cons when used for different applications as listed Read More...

Ceramic Pressure Sensors for High-Volume Applications

Model 301B from BCM SENSOR is a piezoresistive pressure sensor based on ceramics. The bridge circuitry of this sensor is directly printed at the backside of its ceramic diaphragm through the thick-film process. Such the design and the manufacturing process make this model cost-effective especially for batch production for high-volume applications.   The 301B sensor possesses a rigid structure as every sensor is manufactured from one piece of ceramics (i.e., mono-block structure). And thanks to excellent corrosion resistance of ceramics, the Read More...

High-Precision Strain Gauges and Adhesive for Sensor Manufacturing

In manufacturing of force sensors and/or load cells, the most three commonly-used strain gauges (SG) are the linear SG (AA-pattern) for bending beam, the 90°-rosette SG (BB-pattern) for column beam, and the dual shear SG (HA-pattern) for shear-beam force sensors. All of these three categories of SG from BCM SENSOR are both temperature-compensated and creep-compensated, and they are suitable for manufacturing load cells of a combined error down to 0.01%fs. In order to achieve the above-mentioned combined error, the adhesive of Read More...

500G Mono-Block Pressure Sensors Made from 316L Stainless Steel

BCM SENSOR is proud of launching a new version of model 500G pressure sensors which is made from 316L stainless steel (SS). This model is designed for high pressure application up to 5000bar. Thanks to the unique mono-block structure, the 500G sensors can have excellent resistance to overload pressure – proof pressure up to 300%fs while burst pressure up to 500%fs. Moreover, the mono-block structure helps the 500G avoid using any O-ring inside the sensor structure for sealing purpose. Read More...

FD101 Universal Force Sensor Dies

FD101 piezoresistive sensor die is designed for force measurements universally. For example, if one of such the sensor dies is bonded on a bending beam, it forms a half bridge measuring circuit, or if two of such the sensor dies are bonded on the top- and bottom-surface of the bending beam respectively, they form a full bridge measuring circuit. In case of an either tension or compression beam where this sensor die is bonded on, it can form a full Read More...

SE105 Flip-Chip Pressure Sensor Dies for Harsh Environment

SE105 piezoresistive pressure sensor die from BCM SENSOR is designed of a flip-chip structure for harsh environment application.   Thanks to the flip-chip structure, the SE105 sensor die features various superiorities as follows: Both the die-bonding and the wire-bonding processes are simplified to one process. As a result, the SE105 becomes a surface mounting device. The SE105 can contact directly with pressure media and work in harsher environment. This is because its Wheatstone bridge circuitry is located on the back-surface of Read More...
