The product is based on advanced microelectromechanical principles, with a silicon piezoresistive pressure-sense chip utilizing MEMS technology as the key ponent. The pressure sensitive chip consists of an elastic membrane and four resistors integrated on the membrane. The four piezoresistors form a Wheatstone bridge structure, which generates a voltage output signal linearly proportional to the applied pressure when pressure is applied to the elastic membrane. The silicon piezoresistive pressure sensitive chip is mounted on a ceramic substrate and the sensor is calibrated and pensated by thick film technology circuitry to produce a highly accurate standard voltage output signal referenced to the supply voltage. A cap is affixed to the ceramic substrate to protect the internal structure from damage and to facilitate installation in the system. The use of gel on the pressure sensitive chip ensures insulation from the outside. It can be used continuously for 168 hours and should be disposed of properly after use.
