Description

Technical Field

[0001] The utility model relates to the technical field of temperature transmitters, in particular to a 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 that is linearly related to the temperature, a 0-5V / 0-10V voltage signal, and an RS485 digital signal output.

[0003] For example, the Chinese patent with publication number CN218847419U proposes a temperature transmitter, which separates the second filter screen from the protective shell by rotating the bolt on the first filter screen, the activated carbon adsorption screen and the second filter screen, and then pulls the first filter screen and the second filter screen to drive the block to separate from the activated carbon adsorption screen, and then replaces the first filter screen, the activated carbon adsorption screen and the second filter screen to prevent dust from blocking the mesh holes and affecting the heat dissipation effect; by pushing the U-shaped clamp to move to both sides, the U-shaped clamp moves At the same time, it also drives the telescopic rod to compress the first spring, and then the temperature transmitter is placed between the U-shaped clamps, and the U-shaped clamps are slowly loosened. The first spring begins to slowly extend to push the U-shaped clamps to move through the telescopic rod, and the U-shaped clamps clamp and fix the temperature transmitter, which is convenient for protecting the temperature transmitter and preventing the internal parts from being damaged after accidentally falling to the ground. However, in this solution, it is easy to collide or fall when installing the temperature transmitter. Since the internal parts of the transmitter are relatively precise, it is easy to cause damage to the transmitter. For this reason, we propose a temperature transmitter. Utility Model Content
