summary:
The thermal resistance temperature transmitter product developed by Weijunrui Technology is mainly used for Ni1000, NTC 10K, NTC 20K, Pt100，Pt1000，Pt10,
Cu50,Cu100， The isolation and transmission of signals from sensors such as thermocouples J/K/T/E/R/S/B (sensors need to be configured by the user) are mainly used in industry
To measure various temperature signals. The transmitter has linearization and long line compensation functions, and the data is processed by the microcontroller algorithm to ensure the output signal and temperature
Accurate correspondence, when measuring thermocouples, built-in temperature sensors can be used for cold end compensation. When leaving the factory, it is calibrated according to the national standard graduation table, achieving a precision level of 0.1 completely
Degree requirements. Special customization can also be made based on the indexing table provided by the user to meet their measurement needs. The connection between input, output, and auxiliary power supply is complete
Isolation (triple isolation), capable of withstanding an isolation withstand voltage of 2500VDC.
The product adopts the DIN35 international standard guide rail installation method, which is small in size, high in accuracy, stable in performance, and high in cost-effectiveness. It can be widely used in petroleum
Industries such as chemical, power, instrumentation, and industrial control.
The WJ16 series temperature signal isolation amplifier is very convenient to use. Simply connect the wires to achieve isolation and transmission of temperature signals. Specific selection can be made
You can refer to the product selection table or consult the customer service personnel of Weijunrui Technology.
