Description

Technical Field

[0001] The utility model belongs to the technical field of temperature transmitters, in particular to an integrated temperature transmitter. Background Art

[0002] The temperature transmitter uses thermocouples and thermal resistors as temperature measuring elements. The output signal from the temperature measuring element is sent to the transmitter module. After being processed by circuits such as voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, it is converted into a 4-20mA current signal 0-5V / 0-10V voltage signal that is linearly related to the temperature, and an RS485 digital signal output.

[0003] Most of the existing integrated temperature transmitters are used for a long time on pipes in factories or outdoor pipes. Therefore, dust will accumulate on the instrument panel after long-term use, so it needs to be wiped frequently. In addition, the glass on the instrument panel will turn yellow and scratch due to long-term use without protection, which will block the line of sight and make it difficult to see the internal numerical display, resulting in the transmitter being unable to continue to be used or requiring repair and replacement, which greatly increases the cost of using the transmitter.
