WZPK-131 armored thermal resistance works armored thermal resistance is the use of material changes in temperature, its resistance changes with the characteristics to measure the temperature. When the resistance changes WZP- thermal resistance parameters, the working instrument will show the temperature corresponding to the resistance value. The main technical parameters of product performance standards IEC751, JB / T8623-1997, JB / T8622-19975, thermocouple wire thermocouple wire diameter material support in the form of a single double-supported casing diameter Φ3 Φ4 Φ5 Φ6 Φ8Φ4 Φ5 Φ6 Φ8 casing material 1Cr18Ni9Ti1Cr18Ni9Ti resistance three-wire connection. Three-wire connection to eliminate measurement errors caused by lead resistance. This is because the measurement of the thermal resistance of the circuit is generally unbalanced bridge. Thermal resistance as a bridge arm resistance bridge, the connecting wires (from the thermal resistance to the control room) has become part of the bridge arm resistance WZP- thermal resistance, this part of the resistance is unknown and with changes in ambient temperature, resulting in a measurement error. Three-wire RTD WZP- ex wires connected to a power supply terminal of the bridge, and the remaining two were connected to the thermal resistance of the bridge where the arm and the adjacent bridge arm, thus eliminating wire line resistance band to measurement error. The industry is generally a three-wire connection. WZP- RTD manufacturer, Anhui Electric Group, WZP- thermal resistance provided by the Anhui Electric Group Co., Ltd .. Anhui Electric Group Co., Ltd. (www.ahecable.com) is Chuzhou, bare wires and bare conductor products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Anhui Electric Group leadership with the staff warmly welcome all inquiries negotiations to create Anhui Electric Group, a better future.
