Pressure Sensor Dies

Model SE101 - Absolute Pressure Sensor Dies

Model SE101 piezoresistive sensor die is specially designed for high-volume applications, e.g., medical devices, automotive industry, and consumer electronics. This sensor die is manufactured through 6″ wafer silicon-on-silicon process by MEMS technology. It features a miniature dimensions of 0.9mm x 0.9mm x 0.5mm. Thanks to its unique design of the pressure diaphragm, the SE101 possesses not only high sensitivity but also extraordinary overload pressure (proof pressure and burst pressure). As a non-signal-conditioning sensor die, the SE101 is available in a closed-bridge circuit with 4 solder pads. Before packing, each SE101 sensor die is individually tested and qualified to its specifications. Three different types of packaging are available as options to fit different marketing demands. These three types can be found in Ordering Information.

Model SE102 - High-Overload-Pressure Sensor Dies

Model SE102 is designed as a piezoresistive pressure sensor die. Thanks to its design, the model SE102 features high overload pressure (HOP), i.e., high proof pressure and high burst pressure. The HOP enables the sensor die to sustain huge pressure peaks during any transient processes in application. This pressure sensor dies are manufactured through 6″ wafer silicon-on-silicon process by MEMS technology. The unique design of its pressure diaphragm results in the SE102 possessing both high sensitivity of output signal and extraordinary resistance to the overload pressures. This model is designed for absolute, gauge or differential pressure measurements. For gauge or differential pressure reference, there are two types of structure available. One is the silicon-on-silicon structure, i.e., with the silicon constraint, while the other is without the silicon constraint.

Strain Measurement

Linear Strain Gauges

BCM SENSOR linear strain gauges are specially developed for manufacturing precision force transducers which employ bending beam working principle. For the purpose of this specific application, the linear strain gauges are temperature and creep compensated, and they can be either encapsulated or open-face according to the requirement. The karma gauges can be manufactured with effective modulus compensation (EMC). The EMC gauges are mostly for manufacturing low-cost force transducers, because with the EMC gauges the manufacturers can eliminate the use of compensation resistors and achieve the sensitivity compensation.

Torque Measurement - Rotary Torque Transducers

Model 1811 - Non-Contact Rotary Torque Transducers

Model 1811 rotating torque transducer (RTT) is developed to measure rotary torque up to 300,000 Newton-meters (300 kNm). The 1811 is composed of a rotor, a stator and two mechanical bearings in between the rotor and the stator. The rotor acts as a shaft to measure torque, while the stator supplies electric power to the rotor and transmits torque signal from the rotor to a SSC (sensor signal conditioner). Taking advantages of the electromagnetic induction principle, model 1811 has no electric brush between the rotor and the stator for the power and signal transmission. Therefore, this RTT is an ideal device for applications which require long term durability and a few of maintenance of the mechanical bearings.
