Shanghai Xuanxu SBW SeriesIntegrated temperature transmitter

SBW Series OneIntegrated temperature transmitterIt is a combination of temperature sensors and transmitters, which can be used in a very simple way-200~+1600 ℃ Convert the temperature signal within the range to a two-wire system4~20mA DCThe electrical signal is transmitted to the display, regulator, and recorderDCSTo achieve precise measurement and control of temperature. It is an updated product for temperature measurement and control in modern industrial sites and research institutes, and is the * product of distributed systems and digital bus systems.At present, this product is widely used in industrial fields such as petroleum, chemical, power plants, breweries, pharmaceuticals, cement, textiles, food, environmental monitoring, boilers, rubber, etc.

Integrated temperature transmitterIt is a new type of temperature measuring instrument with ultra small size, excellent performance, and high precision. It has the characteristics of small size, light weight, and easy use and installation. It can be directly installed in the junction box of general industrial thermal resistors and thermocouples, forming an integrated structure with on-site sensing components. This not only saves expensive compensation wires and cables, but also reduces signal transmission distortion and interference, thereby obtaining high-precision measurement results.

Integrated temperature transmitterMain features:
•output4-20mAor0-10mAThe standard constant current signal is only linearly related to the measured temperature and is independent of the size of the load resistance.
•Output high impedance, large signal, and no RF interference.
•It has the functions of explosion prevention, shock resistance, moisture resistance, heat resistance, and protection against harmful gases.
•Equipped with reverse polarity protection function for power supply.
•It has strong remote transmission function and is extremely convenient to install and use.
•The thermocouple transmitter itself has cold end compensation, no need for external compensation wires, and its compensation measures.

Explanation: If the input distance is far and affects the accuracy, several models of temperature transmitters can be made into a three wire input connection without the need for compensation wires, thereby reducing errors and improving accuracy.
The temperature transmitter uses thermocouples and thermistors as temperature measuring elements. The output signal from the measuring element is sent to the transmitter module, which undergoes voltage stabilization filtering, operational amplification, and nonlinear correctionV/IAfter circuit processing such as conversion, constant current, and reverse protection, it is converted into a linear relationship with temperature4～20mAor0～10mAConstant current signal output. The principle diagram is shown below:

Integrated temperature transmitterNote:
1.The lead between the thermistor and the transmitter terminal should be shortened as much as possible to reduce unnecessary accuracy loss.
2.The signal line connected to the transmitter can be a regular twisted pair cable.
