Pressure Sensors

Simple pressure switch uses contracts to complete electrical circuit
This section discusses the various types of pressure sensors that are used in automotive applications. In some instances, a simple pressure switch is used. In systems that require monitoring of the exact pressure electromechanical pressure sensors, piezoresistive, or piezoelectric sensor are used. These sensors convert the applied pressure to an electrical signal. A wide variety of materials and technologies has been used in these devices. These sensors are used to measure the atmospheric air pressure, manifold pressure, pressure of a gas (such as R134a), exhaust pressures, fluid pressures, and so forth. The types of sensors that can be used include; potentiometric, strain gauges using Wheatstone bridges or capacitance discharge, piezoelectric transducers, and pressure differential sensors. Pressure Switches FIGURE. Simple pressure switch uses contracts to complete electrical circuit. Pressure switches will usually use a diaphragm that works against a calibrated spring or other form of tension. When pressure is applied to the diaphragm that is of a sufficient value to overcome the spring tension a switch is closed. Current that is supplied to the switch now has a completed path to ground. In a very simple warning light circuit, the closed pressure switch completed the circuit for the bulb and alerts the driver to an unacceptable condition. For example a simple oil pressure warning lamp circuit will use a pressure switch. FIGURE. Computer monitors pressure switch circuit. Computer monitored pressure switch circuits use the change in voltage as an indication of pressure. When the pressure change (either from low to high or high to low) changes the state of the switch, the voltage change is interpreted by the computer. Pressure switches are used to monitor the presence of pressure that is above or below a setpoint; they do not indicate the exact amount of pressure being applied. Potentiometric Pressure Sensor FIGURE. Potentiometric pressure sensors use a Bourdon tube, capsule, or bellows to drive a wiper arm on a resistive element. One of the basic types of pressure sensor is the potentiometric pressure sensor. The potentiometric pressure sensors use a Bourdon tube, a capsule, or bellows to move a wiper arm on a resistive element. Using the principle of variable resistance, the movement of the wiper across the resistive element will record a different voltage reading to the computer. Although this type of sensor can be used as a computer input, a computer is not always involved. Some early analog instrument panels used this sensor unit with an air core...
