It is used as a sensor for knowing the engine knock. A temperature sensor is a device, typically, a thermocouple or resistance temperature detector, that provides temperature measurement in a readable form through an electrical signal. Usually a transducer converts a signal in one form of energy to a signal in another.. Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc. Voltage Temperature Sensor 1 °C +/-2 °C 19.53 mV / °C 3.1 to 5.5 V 6μA (12 μA Max) SC70-5 SOT23-5 MCP9701A: Microchip TC1046: Analog Voltage Temperature Sensor -40 to +125 °C 0.5 °C +/-2 °C 6.25 mV / °C 2.7 to 4.4 V 35 μA 174 to 1205 mV SOT23B TC1046: Microchip TC1047: Analog Voltage Temperature Sensor -40 to +125 °C 0.5 °C Semiconductor temperature sensors are the devices which come in the form of integrated circuits i.e. It is shaped into a disc, a rod or a bead. In a Temperature Sensor, the changes in the Temperature correspond to change in its physical property like resistance or voltage. There are a wide range of different temperature sensors available for applications specific purposes. To do this, you work with a temperature probe or an integrated sensor. Key specifications include sensor type and intended application, along with any particular transducer features. More than thousands of devices can be fabricated upon thin silicon wafers. More information on vision and imaging sensors may be found in our related guide All About Vision and Imaging Sensors. Bead thermistors may be only a few millimetres in diameter. It is directly calibrated in Celsius (Centigrade) and have a full operating range between -55 C 0 to +150 C 0. In particular, preventative reliability is a core application for temperature sensors, which help ensure a system is functioning properly, and determine whether there are impending risks of danger or malfunction.
