Technical Field
[0001] This utility model relates to the field of industrial automation technology, specifically to an intelligent temperature transmitter. Background Technology
[0002] In the field of industrial automation and process control, temperature measurement is a crucial component. Traditional temperature measurement equipment often uses analog circuits for signal processing, resulting in relatively low measurement accuracy and intelligence, which makes it difficult to meet the modern industrial demand for high-precision, high-stability, and intelligent measurement.
[0003] Traditional temperature measurement devices typically use thermocouples or resistance temperature detectors (RTDs) as temperature sensing elements. They convert the resistance changes of the sensing elements into voltage or current signals through analog circuits for output. However, this method of transmitting and processing analog signals is susceptible to external interference, leading to a decrease in measurement accuracy. In addition, traditional temperature measurement devices usually only have a single output function, such as a 4-20mA current signal output, and lack the ability for remote communication and intelligent control, which limits the application of the equipment in complex industrial environments.
[0004] In view of this, we will study and improve the existing structure and its shortcomings to provide an intelligent temperature transmitter, in order to achieve a more practical value. Utility Model Content

The interface type and electrical parameters of the electrical connector can be selected and configured according to actual needs.
[0011] Preferably, the LED digital display screen and the adjustment button are respectively located on the inner bottom surface of the groove, and are connected to the temperature probe and the transmitter head through an internal circuit, wherein an ARM series microcontroller is embedded in the transmitter head.
[0012] Compared with the prior art, this utility model provides an intelligent temperature transmitter with the following advantages:
[0013] By integrating an ARM series microcontroller as the core processor, the intelligent reading and conversion of the resistance signal output by the temperature probe is realized. This process not only improves the accuracy of temperature measurement but also endows the transmitter with a high degree of intelligence. Through the built-in algorithm, the microcontroller can convert the resistance signal into a temperature value in real time and display it on the LED digital display screen, providing intuitive and accurate temperature data for on-site operators.

This multi-functionality allows the transmitter to easily connect to various monitoring systems and control networks, achieving real-time monitoring, recording, and analysis of temperature data. Furthermore, through the RS485 communication interface, the transmitter can exchange data with a host computer or other intelligent devices, enabling remote parameter setting and fault diagnosis, further enhancing the reliability and ease of use of the equipment. In addition, the snap-fit connection between the temperature probe and the transmitter head, along with the external thread design, allows for convenient installation on pipes or equipment of different sizes, while providing excellent sealing and waterproofing performance, thus adapting to various complex application scenarios and harsh environmental conditions. This multi-functionality and wide applicability make the ZWB intelligent temperature transmitter a promising candidate for applications in industrial automation and process control.

[0024] Furthermore, the electrical connector 3 is fixedly connected to one side of the outer end of the transmitter head 1. The front end of the electrical connector 3 is electrically connected to the power supply to realize the transmission and processing of temperature signals. The interface type and electrical parameters of the electrical connector 3 can be selected and configured according to actual needs.
[0025] Furthermore, the LED digital display screen 6 and the adjustment button 7 are respectively located on the inner bottom surface of the groove and are connected to the temperature probe 2 and the transmitter head 1 through internal circuitry. The transmitter head 1 is embedded with an ARM series microcontroller. The LED digital display screen 6 is used to display the temperature measurement results in real time, while the adjustment button 7 is used to adjust the measurement range, accuracy, or other parameters of the equipment to meet the user's personalized needs. In addition, the design of the groove also serves to protect the LED digital display screen 6 and the adjustment button 7 from damage or contamination by the external environment.
[0026] Working Principle: The core component of the device is the temperature probe 2, which typically uses a platinum resistance thermometer or a copper resistance thermometer as the temperature sensing element. When the temperature probe 2 comes into contact with the object being measured, the temperature sensing element will generate a corresponding change in resistance according to the temperature change of the object. The resistance change generated by the temperature probe 2 is converted into an electrical signal. This conversion process is usually completed inside the transmitter head 1, which has an embedded ARM series microcontroller as its core processor. It can read the resistance signal output by the temperature probe and convert it into a temperature value through a built-in algorithm. The converted temperature value is displayed in real time on the LED digital display on the top of the transmitter head 1. On display screen 6, the screen uses LED digital tube technology, featuring intuitive display and accurate readings, allowing on-site operators to easily view temperature data at any time. In addition to its display function, the transmitter also has a 4-20mA current signal output function. This function enables remote transmission of temperature data to other monitoring equipment or controls, achieving real-time monitoring and recording of temperature data. To meet more complex communication needs, the transmitter is also equipped with an RS485 communication interface. Through this interface, the transmitter can exchange data with a host computer or other intelligent devices, realizing remote monitoring of temperature data, parameter setting, and fault diagnosis. The transmitter head 1 features functions such as fault diagnosis. An adjustment button 7 is located in a groove on the upper end of the transmitter head 1. Users can press these buttons to set or adjust parameters such as the transmitter's output range and accuracy. This function allows the transmitter to be customized according to different application scenarios and user needs. The operation signal from the adjustment button is transmitted to the internal ARM microcontroller for processing. The microcontroller adjusts the internal algorithm and parameter settings based on user input, thereby achieving precise control of temperature measurement and output. The temperature probe 2 is connected to the transmitter head 1 via a snap-fit connection, ensuring the probe is stably and securely fixed to the lower end of the transmitter head. This connection method not only improves the accuracy and stability of temperature measurement but also facilitates equipment installation and maintenance. The lower end of the temperature probe has an external thread 4, which can be threaded to an external mounting structure to fix the entire device. The specifications and dimensions of the external thread can be customized according to actual needs to meet the requirements of different application scenarios. A sealant is applied to the outer surface of the mounting head 5 to prevent interference or contamination from the external environment from affecting temperature measurement. Simultaneously, the sealant ensures the overall sealing and waterproof performance of the equipment, improving its reliability and service life.
