Housing of temperature transmitter

Abstract

The invention discloses a housing of a temperature transmitter. The housing is composed of a U-shaped metal shell and a metal cover plate, wherein the U-shaped metal shell and the metal cover plate are connected via a bolt. The outer surfaces of the U-shaped metal shell and the metal cover plate are coated with an insulating layer, respectively. The inner surfaces of the U-shaped metal shell and the metal cover plate are successively coated with an aluminum foil layer and a modified nano-diamond layer. The inner surface of the bottom of the U-shaped metal shell is further provided with a clamping groove. The control board of the temperature transmitter is clamped in the clamping groove. A heat sink is stuck to the bottom of the control board. The bottom of the heat sink is in contact with the modified nano-diamond layer. The top of the opening of the U-shaped metal shell is provided with a groove. A sealing ring is arranged in the groove. The bottom of the cover plate is provided with a clamping edge capable of extending into the groove. The bottom of the clamping edge is obliquely arranged. The sealing ring is provided with a hollow cavity, a bevel edge and a flanging. A spring is arranged in the hollow cavity of the sealing ring. The bevel edge is in linear sealed cooperation with the oblique bottom of the clamping edge. The flanging is clamped with the inner sidewall of the groove. Due to the adoption of the above structure, the housing of the temperature transmitter is good in sealing and waterproof performance and high in self-heat dissipation efficiency, which can prevent the signal interference.

Description

technical field [0001] The invention relates to a sealed casing of a sensor for meteorological detection, in particular to a casing for a temperature transmitter. Background technique [0002] Temperature transmitters mostly use temperature probes as temperature measuring elements to collect temperature signals, and convert them into current after being processed by circuits such as voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection. Signal or voltage signal output can also be directly output through 485 or 232 interface through the main control chip. [0003] Temperature data is currently an important indicator for detecting ambient temperature values, and temperature collectors are used in the collection of environmental data in various industries. These temperature collectors usually use their own external communication methods and communication protocols, and usually cannot communicat...
