A temperature transmitter is a device used to measure and transmit temperature signals by converting a temperature sensing element, such as a thermocouple or thermistor, into a standard signal output for easy monitoring, control, and recording of temperature changes. Temperature transmitters are widely used in a variety of industries, including industrial automation, energy, chemicals, pharmaceuticals, food and beverages, and more. They play a key role in monitoring and controlling temperature in real time, helping to ensure the stability, product quality and safety of the production process.
The integrated temperature transmitter is a new type of ultra-small temperature measuring instrument with excellent performance and high precision. It has the characteristics of small size, light weight, and convenient installation. It can be directly installed in the junction box of general industrial thermal resistance and thermocouple, and forms an integrated structure with field sensing elements. This not only saves more expensive compensation wires and cables, but also reduces signal transmission distortion and interference, thereby obtaining high-precision measurement results.
The transmitter can be used with various regulators, especially suitable for microcomputer multi-channel data acquisition, measurement and control. It is used in conjunction with the intelligent industrial signal detector produced by our company to form a multi-channel temperature cycle detection system in the control room.
At present, the product is widely used in petroleum, chemical, power plants, breweries, medicine, cement, textiles, food, environmental monitoring, boilers, rubber and other industrial fields.
Main features of integrated temperature transmitter
●Output 4～20mA or 0～10mA standard constant current signal, which only has a linear relationship with the measured temperature, and has nothing to do with the size of the load resistance.
●Output high impedance, large signal, no radio frequency interference.
●It has the functions of explosion-proof, shock-proof, moisture-proof, heat-proof and harmful gas protection.
●With power supply polarity reverse protection function.
●With strong remote transmission function, it is extremely convenient to install and use.
●The thermocouple transmitter itself has cold junction compensation, without external compensation wires and other compensation measures.
●The intelligent integrated belt is based on the HART communication protocol, which makes its performance more perfect.
●High precision, low power consumption, wide operating environment temperature range, stable and reliable work.
●With on-site display function, eliminating the need for secondary instruments.
