Different types of temperature sensors are wired differently. Here are a few common temperature sensors.
*** Kind: Platinum resistance PT100/PT1000 wiring.
Temperature sensors packaged in PT100/PT1000 generally have three outlet modes: two-wire, three-wire, and four-wire. As the name suggests, the two-wire system is to lead out two wires. The wiring of the two-wire system is very simple. You can find the wiring position of the upper-level instrument. The three-wire two-signal wire has a compensation wire. If the upper-level instrument has only two terminals, then The leads of the sensor are divided into two groups, one set of one signal line, one set includes one signal line and one compensation wire. When the manufacturer produces the temperature sensor, it usually uses different color lines to distinguish. If there is no color distinction, it needs Use the meter to measure the resistance and distinguish the signal line from the compensation wire to rewire. The four-wire system is the same as the two-wire system. It is only divided into two groups. Each group has one signal line and one compensation wire. The HX-RS high-precision platinum resistance temperature sensor is usually two red, two white and two wires. The line specification will be defined in the product manual. If there is any doubt during wiring, you can directly communicate with the manufacturer.
Second: Digital temperature sensor DS18B20.
The DS18B20 is a component of the TO92 package. It has three pins. The temperature sensor is usually packaged in two-wire or three-wire. When wiring, the wiring should be strictly in accordance with the line sequence on the instruction manual. If the connection is reversed, the chip may be burned. . Different manufacturers have different line order definitions and different line habits. The instruction manual is not universal, so it is recommended to find the original manufacturer to inquire about the wiring method *** is reliable.
The third type: AD590 temperature sensor.
The AD590 temperature sensor is a monolithic integrated temperature measuring component produced by American Analog Devices. The appearance of the metal shell has three pins, one of which is the positive terminal V+ of the power supply; the second is the current output terminal I0; the third leg is the tube case, generally not used. . Therefore, the common AD590 temperature sensor is two-wire, and the wiring is relatively simple. The AD590 can withstand a forward voltage of 44V and a reverse voltage of 20V. Therefore, the reverse connection of the device will not be damaged.
Whether the temperature sensor wiring can accurately read the temperature is critical. For example, the common reading of the platinum resistance temperature sensor, the 85 °C displayed by the DS18B20, and the continuous beating are caused by incorrect wiring of the temperature sensor. Therefore, before using the temperature sensor, Read the instruction manual carefully and consult the factory if necessary.
