Intelligent temperature transmitter with protection function

Abstract

The invention discloses an intelligent temperature transmitter with a protection function, and belongs to the field of temperature transmitters, the intelligent temperature transmitter with the protection function comprises a transmitter body and a thermocouple, the outer side of the transmitter body is sleeved with a protection shell and a shell cover, the outer side of the thermocouple is sleeved with a sheath, and a quick locking mechanism is arranged between the protection shell and the shell cover. The top end of the sheath is provided with a container connecting piece, the top of the container connecting piece is fixedly provided with an adapter tube, the sheath is detachably connected to the bottom end of the adapter tube through a threaded structure, the top end of the thermocouple is fixedly provided with a sliding block, the thermocouple is slidably connected to the inner wall of the adapter tube in a sleeving mode through the sliding block, and the inner wall of the adapter tube is provided with a conductive sliding rail; and a conductive contact matched with the conductive slide rail is arranged on the slide block. According to the invention, over-temperature retraction protection and shock absorption and heat insulation protection can be autonomously carried out, and compared with the traditional technology, the structure is simple, the service life is longer, the market prospect is achieved, and the intelligent temperature transmitter is suitable for popularization.

Description

technical field [0001] The invention relates to the field of temperature transmitters, in particular to an intelligent temperature transmitter with protection function. Background technique [0002] The transmitter is a converter that converts the output signal of the sensor into a signal that can be recognized by the controller (or converts the non-electricity input by the sensor into an electrical signal and amplifies it for remote measurement and control). Sensors and transmitters together constitute a monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transmitters. There are many types of transmitters. The transmitters used in industrial control instruments mainly include temperature transmitters, pressure transmitters, flow transmitters, current transmitters, voltage transmitters, etc. The temperature transmitters use Thermocouples and thermal resistors are used as temperature measuring elements, a...
