Description

Technical Field

[0001] The utility model relates to the technical field of temperature transmitters, and particularly relates to a high-temperature stable temperature transmitter. Background Art

[0002] The temperature transmitter uses a thermocouple or a thermal resistor as a temperature measuring element. The signal output from the temperature measuring element is sent to the transmitter module, and 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 4-20 mA current signal, a 0-5V / 0-10V voltage signal, or an RS485 digital signal that is linearly related to the temperature.

[0003] When the existing temperature transmitter is in use, it is necessary to connect the temperature transmitter to a connecting rod to facilitate fixing the temperature transmitter at a specified position. The traditional connection method is to insert the connecting rod into the stabilizing transmitter and fasten it by means of a threaded connection. However, the temperature transmitter is relatively large in size, and fastening it manually places a heavy burden on the staff. At the same time, there may also be problems with insecure connection. To address the above problems and deficiencies, a high-temperature stable temperature transmitter is urgently needed. Summary of the Utility Model

[0030] As Figure 2 and Figure 3 shown, a rubber pad 3 is fixedly assembled at the bottom of the temperature transmitter body 1, and the bottom of the rubber pad 3 abuts against the top of the connecting rod 2 and the moving ring 23. By providing the rubber pad 3, it is beneficial to improve the tightness of the connection between the temperature transmitter body 1 and the connecting rod 2, reduce the gap at the connection, and improve the stability of the device during use.

[0031] As Figure 2 and Figure 3 shown, a guiding groove 4 is provided at the port of the inner wall of the connecting rod 2, and the bottom of the fixing pin 11 adopts a rounding process. By providing the guiding groove 4 and the limitation of the fixing pin 11, it is beneficial to improve the accuracy and smoothness of the insertion of the fixing pin 11 into the inner wall of the connecting rod 2.

On the contrary, repeating the above steps, the groove 5 can guide the ball 25, so that the ball 25 is separated from the card slot 12, and the temperature transmitter body 1 can be separated from the connecting rod 2;

[0035] By setting the rubber pad 3, it is beneficial to improve the tightness of the connection between the temperature transmitter body 1 and the connecting rod 2, reduce the gap at the connection, and improve the stability of the device during use.
