Transducers are available in plastic composite, bronze or stainless steel to fit practically any boat on the water. Direct wiring sensors to a control system requires the use of sensor extension wires. Normal-pressure transducers are commonly rated for temperatures between 51° to 93° C. However, high-temperature pressure transducers are specifically designed to handle high temperatures of the steam. There are different views and definitions of sensors and transducers. When the two junctions are at different temperatures, a voltage is developed across the junction which is used to measure the temperature. Particulate matter sensors use the light scattering method to detect and count particles in a given environment. So, thermocouple is an temperature transducer. Bently Nevada†’s 3300 XL High-Temperature Proximity System (HTPS) withstands extreme temperatures (rated for +350°C or +662°F). The temperature coefficient of the sensor element mostly depends on the purity of the platinum used to make the wire. Sunlight sensor. It works on the principle that the metals have different temperature coefficient and when these two metals join together then the voltage induces, and this voltage is directly proportional to the temperature. This includes the 4-20 mA or 0-10 V signals. Comparing Pressure Transducers and Transmitters.
