Temperature sensors both in industry and agriculture and service industry has a wide range of applications, such as temperature sensor can be used alone can also be used with secondary instrument, there are many customers like to buy the temperature sensor used with instrument, but tend to appear in the process of using the following a few questions.
Common is pt100 temperature sensor or pt1000, when we use these matching instrument used to set the instrument input to corresponding pt100 or pt1000, followed by assisting the instrument use must require pt100 or pt1000 are three wire system, so as to eliminate the influence of the resistance. Followed by 4-20 ma output of temperature sensor, which is what we call the temperature transmitter, when the temperature sensor used in assisting the instrument need to set the instrument of the input signal into a 4-20 ma, followed by wiring, 4-20 ma temperature sensor is generally two wire system, if you need any instrument to give it power supply we will on the power meter feed sensor, signal line access to the instrument input, if you don't need the instrument power supply we can from the actuators to a power supply, the sensor into then signal lines to the instrument, the instrument earth anode connection and sensors.
Temperature sensor used with instrument has been very common, temperature sensor and digital display integration at present, this kind of sensor itself with display, don't need wiring so we use rise more convenient, but the screen is small, it is not easy to observe and record the data, so the temperature sensor used with secondary instrument or the majority, is convenient to observe and record the digital display and remote data. The use of great convenience for customers.
