Abstract

The invention discloses a temperature transmitter housing capable of heat dissipating and sealing, and an U-shaped metal housing and a metal cover plate which are connected through a bolt. The external surfaces of the U-shaped metal housing and the metal cover plate are coated with insulating layers, and the internal surfaces of the same are coated with aluminum foil layers and modified nanometer diamond layers in sequence. The bottom of a control plate of a temperature transmitter is pasted with a heat dissipating fin, and the bottom of the heat dissipating fin contacts with the modified nanometer diamond layers; a groove is arranged on the top of an opening of the U-shaped metal housing, and a sealing ring is arranged in the groove. The sealing ring is prepared through a conventional method with the following raw materials by weight: 50-60 parts of Buna-N rubber, 40-50 parts of silicone rubber, 20-30 parts of polyether urethane rubber, 10-20 parts of aromatic poly-parabens heat-resistant resin, 5-15 parts of carbon fluoride, 2-5 parts of active magnesium oxide, 1-3 parts of antioxidant and 1.2-2.5 parts of self-lubricating agent unsaturated fatty acid. By adopting the above structure and constituents, the sealing ring has good sealed waterproof performance and high self-heat dissipating efficiency, and can prevent signal interference.

Description

technical field [0001] The invention relates to a sealed casing of a sensor for meteorological detection, in particular to a heat-dissipating and sealed temperature transmitter casing. 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 usu...
