Product description
I. Overview
The integrated K-type thermocouple fixed cone thread integrated thermocouple WRNB-630 organically integrates temperature sensing elements (thermistor or thermocouple) with signal conversion amplification units, and is used to measure the temperature of liquids, vapors, and other gas media or solid surfaces within the range of -200-1600 ℃ in various process flows. Integrated K-type thermocouples are usually used in conjunction with display instruments, recording instruments, and various control systems. It has the characteristics of simple structure, easy installation, use, and maintenance, and is currently widely used in industries such as petroleum, chemical, metallurgy, power plants, and light industry.
The integrated K-type thermocouple fixed cone thread is composed of a temperature sensor and a signal converter. The signal converter is installed in the cold junction box of the temperature sensor. The temperature sensor is affected by temperature and produces resistance or potential effects, which are converted into a differential voltage signal. This signal is amplified by an amplifier, and then converted into voltage and current to output a 4-20mA current signal or other 0-5V/0-10V signals corresponding to the measurement range.
The integrated K-type thermocouple is divided into three categories: ordinary type, explosion-proof type, and digital integrated type. Among them, ordinary and explosion-proof models can choose different built-in temperature transmitter modules to meet different application requirements of users. Temperature transmitters are divided into two series: thermocouples and thermistors, depending on the type of temperature sensor used.

3、 Selection
4、 Product Features
1. Can be transmitted in a two-wire system. The two wires powered by the signal converter also transmit output signals simultaneously
2. Output constant current or constant voltage signals, with strong anti-interference ability and good long-distance transmission performance.
3. The signal converter is encapsulated in epoxy resin as a module, which has the advantages of vibration resistance, corrosion resistance, moisture resistance, etc., and can be used in places with poor conditions.
4. The millivolt signal of the thermocouple is directly converted into a 4-20mA current output through a signal converter, and the signal is transmitted using ordinary cables, which can save expensive compensation wires.
5. The temperature transmitter with on-site display not only outputs a current signal of 4-20mA, but also can read the measured temperature at the temperature measurement site, which brings great convenience to operators.
6. High precision, anti-interference, good long-term stability, maintenance free, and capable of remote transmission (up to 1000 meters).
