Temperature transmitter with protection and shock absorption functions

Abstract

The invention relates to the technical field of temperature transmitters, and discloses a temperature transmitter with protection and shock absorption functions. The temperature transmitter comprisesa mounting plate, through holes are formed in four corners of the mounting plate; a first guide rod is arranged in the middle of the through hole; the lower ends of the first guide rods are connectedwith fixing plates; a temperature transmitter body is arranged in the middle of the lower surface of the fixed plate; a second fixed seat is arranged in the left side of the upper surface of the mounting plate; the upper portion of the second fixed seat is slidably connected with a second guide rod, the lower end of the second guide rod is connected with a pressing plate, the pressing plate is slidably connected to the middles of first sliding grooves in the front side and the rear side of the second fixed seat, and a first fixed seat is arranged on the right side of the mounting plate. The temperature transmitter with the protection and shock absorption functions is provided with the first fixed seat, the second fixed seat and the top plate to completely clamp the temperature transmitterand a cross rod needing to be fixed, and the stability of the temperature transmitter in the operation process is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of temperature transmitters, in particular to a temperature transmitter with protection and shock absorption functions. Background technique [0002] The temperature transmitter uses thermocouple and thermal resistance as the temperature measuring element, and the output signal from the temperature measuring element is sent to the transmitter module, after voltage stabilization filtering, operational amplification, non-linear correction, V / I conversion, constant current and reverse After the protection circuit is processed, it is converted into a 4-20mA current signal 0-5V / 0-10V voltage signal linearly related to the temperature, and the RS485 digital signal is output. When using this device, usually in order to ensure the normal use of the transmitter, it is necessary to deal with the shock absorption of the transmitter. [0003] The Chinese patent (Announcement Number: CN209280153U) discloses a temperature trans...

AI Technical Summary

Problems solved by technology

The temperature transmitter with protection and shock absorption function, through the first sliding rod, the first sliding sleeve, the first spring, the second sliding rod, the second sliding sleeve, the second spring, the first connecting rod, the second connecting rod , the first pin shaft, the second pin shaft, the third pin shaft and the fourth pin shaft work together to realize the shock absorption of the temperature transmitter body and reduce the internal components caused by the severe vibration of the temperature transmitter body. The probability of damage, thus ensuring the service life of the temperature transmitter body, but the device is not stable enough to hang through the hook, and the installation method of the installation hole is not convenient enough, so the device needs to be improved
