Wireless temperature transmitter with pull-out detection mechanism

Abstract

The invention relates to the technical field of temperature detection, in particular to a wireless temperature transmitter with a pull-out detection mechanism, which comprises a top mounting seat witha built-in single chip microcomputer, a display module and a wireless transmission module, a bottom connecting seat fixed at the lower end of the top mounting seat, and a temperature sensor. The wireless temperature transmitter with the pull-out detection mechanism is composed of a top mounting base, a bottom connecting base and a bottom guide locking pipe of the wireless transmission module, anelastic winding rope storage box is arranged in an external thread mounting base, and the single-chip microcomputer and the temperature sensor are connected through a flexible data transmission line.The position of the temperature sensor can be pulled and adjusted as required, so that the structure and the position of the temperature sensor are adjustable, and the application range is wider; thetelescopic length of the flexible data transmission line can be conveniently locked and fixed, and the use is more stable and convenient; and the storage and fixation are facilitated, meanwhile, the safety and the stability of the flexible data transmission line and a temperature sensor connecting end are improved by utilizing a second lateral loading and unloading notch.

Description

technical field [0001] The invention relates to the technical field of temperature detection, in particular to a wireless temperature transmitter with a pull-out detection mechanism. Background technique [0002] The temperature transmitter is developed from a temperature sensor, any sensor for temperature measurement that can output a standard signal. A standard signal refers to a signal whose form and quantity range of physical quantities conform to international standards. Since the DC signal is not affected by the inductance, capacitance and load properties in the line, and there is no phase shift problem, the International Electrotechnical Commission (IEC) uses the current signal 4mA~20mA (DC) and the voltage signal 1V~5V (DC) Determined as a unified standard for analog signals in process control systems. The temperature transmitter works based on the principle of negative feedback, and it is mainly composed of a measurement part, an amplifier and a feedback part. Th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved wireless temperature transmitter with a pull-out detection mechanism is provided to solve the detection module at the bottom of the current temperature transmitter on the market. The structure is mostly fixed and cannot be adjusted according to needs, so it can only adapt to different equipment and environments by replacing the detection module as a whole. The cost of use is high, and the adjustment operation is also very inconvenient.
