Description

Temperature transmitter

Technical Field

The invention relates to the technical field of transmitters, in particular to a temperature transmitter.

Background

The temperature transmitter adopts a thermocouple and a thermal resistor as temperature measuring elements, signals output by the temperature measuring elements are sent to a transmitter module, and are converted into 4-20 mA current signals 0-5V/0-10V voltage signals which are in linear relation with temperature after being processed by circuits such as voltage stabilizing filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse protection, and RS485 digital signals are output. And the device converts the physical measurement signal or the common electric signal into a standard electric signal to be output or can output in a communication protocol mode. Temperature transmitters are instruments that convert temperature variables into a transmittable standardized output signal, and are mainly used for measuring and controlling temperature parameters of industrial processes. The current transducer converts the alternating current of the main loop to be measured into a standard signal of a constant current loop, and continuously transmits the standard signal to the receiving device. The temperature current transducer converts the signal of the temperature sensor into a current signal, and is connected to the secondary instrument so as to display the corresponding temperature. For example, the temperature sensor is shown as PT100, and the temperature-current transducer is used to convert the resistance signal into a current signal, which is input to the meter to display the temperature. In the use of temperature transmitter, when temperature transmitter measured the higher object of temperature, temperature transmitter can't dispel the heat, leads to the testing result to have the deviation, can cause the component to damage when the temperature is too high, consequently urgently needed a temperature transmitter that heat dispersion is good.
