A temperature transmitter (hakk-wb) is an instrument that converts a temperature variable into a normalized output signal that can be transmitted. The installation of the desuperheater guide rail in the cabinet is small and light, and the microcirculation in the cabinet is improved. The lower working environment temperature can reach -40°C for one second, and the automatic temperature control surface temperature is low and will not corrode, ensuring the safety of surrounding components. A live display is a safety device that is directly installed on the indoor electrical equipment to visually display whether the electrical equipment has operating voltage. When the equipment has operating voltage, the display window of the display flashes to warn people that the high-voltage equipment is electrified, and there is no indication when there is no electricity. Indoor electromagnetic lock is an electronic control mechanism interlocking device for preventing the misoperation of high-voltage switchgear electrical appliances. It is mainly suitable for the front and rear cabinet doors, isolating switches, circuit breakers, grounding wires and other parts of indoor high-voltage switchgear that need to be locked to achieve interlocking to prevent misoperation. It is an indispensable locking device for power generation and power supply departments. The power supply of the temperature transmitter cannot have a peak value, otherwise the transmitter will be easily damaged. Temperature sensors should be calibrated every 6 months. If the dwb cannot stop the linearity correction due to the limitation of the circuit, it is better to select the range to ensure its linearity.
1. Principle-function of temperature transmitter
2. The function research of temperature transmitter is to convert physical measurement signal or ordinary electrical signal into a standard electrical signal output or a device that can be managed and output by communication network protocol. The temperature transmitter is an instrument that converts the temperature environment variable into a normalized output voltage signal that can be transmitted. It mainly includes the measurement and control of different temperature-related parameters in China’s industrial production process. The current transmitter converts the AC working current of the main circuit under test into a constant current loop standard market signal, and continuously sends it to the receiving installation.
3. Working principle of temperature and pressure transmitter–characteristics Temperature transmitters are usually used in conjunction with display instruments, recorders, electronic computers, etc., mainly because they have the following characteristics:
1) Two-wire system output dc4-20ma current signal, strong anti-interference ability;
2) Save the cost of compensating for wire and device working temperature and pressure transmitter;
3) The measurement range is large;Automatic compensation of cold junction temperature and nonlinear correction circuit.
