Description

Technical Field

[0001] The invention relates to the technical field of temperature detection, in particular to a wireless temperature transmitter with a structurally adjustable detection mechanism. Background Art

[0002] Temperature transmitters are developed from temperature sensors, and are temperature measurement sensors that can output standard signals. Standard signals refer to signals whose form and quantity range of physical quantities conform to international standards. Since DC signals are not affected by the inductance, capacitance and load properties of the line, and do not have phase shift problems, the International Electrotechnical Commission (IEC) has determined current signals of 4mA to 20mA (DC) and voltage signals of 1V to 5V (DC) as unified standards for analog signals in process control systems.

[0003] The temperature transmitter works based on the negative feedback principle. It mainly consists of a measuring part, an amplifier and a feedback part. The measuring part is used to detect the measured variable and convert it into an input signal (voltage, current, displacement, force or torque, etc.) that can be accepted by the amplifier. The feedback part converts the output signal of the transmitter into a feedback signal and then sends it back to the input end. The algebraic sum of the zero-adjusting signal is compared with the feedback signal, and the difference is sent to the amplifier for amplification and converted into a standard output signal. At present, there are two types of temperature transmitters on the market: wired and wireless. The difference between the two is mainly in data transmission. The data is processed and then displayed and transmitted through the detection module at the bottom. The structure of the detection module at the bottom is mostly fixed and cannot be adjusted as needed, resulting in it being able to adapt to different equipment and environments only by replacing the detection module as a whole. The cost of use is very high and the adjustment operation is also inconvenient. Summary of the invention
