WRN fabricated thermocouples - WRN-133

SBWZ/R thermocouple (resistance) integration temperature transmitter is DDZ-S series of instrument installation temperature change type send unit. It consists of thermocouple, heat resistance and temperature transmitter module, using two wire way, with nonlinear correction circuit, direct measurement of industrial process-200 °C ~ + 1600 °C within the scope of the liquid, gas medium and all kinds of material of temperature, temperature signal into a will and a linear temperature signal of the 4 ~ 20 mADC current output signal, send display, adjust record instrument or the computer to carry on the distributed control.
The product is widely used in petroleum, chemical, metallurgical, power, light industry and textile, food and other industries, can be and moving coil instruments, digital instrument, recording instrument, regulators, computers and other supporting the use of various measurement temperature control system.

Feature
