Thermal resistance using 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, this part of the resistance is unknown and with changes in ambient temperature thermal resistance indexing table production, resulting in measurement error. Three-wire RTD indexing table, will lead one to the power side 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 brought measurement error. 2, the thermal resistance of the heat resistance as a function of temperature measurement devices have temperature stability, high accuracy, fast response thermistor indexing table price, good corrosion resistance, high impact-resistant ability. Industrial production is the use of the thermal resistance of these characteristics and the temperature points to be monitored by the thermoelectric properties of the temperature sensing element of physical quantities into electrical signals offer thermal resistance indexing table, very easy remote and real temperature value is displayed so that the operating personnel real-time observation and understanding of the entire media operating conditions in order to guide the correct operation of the operating personnel. I have much of the temperature element is used as a measurement of metal platinum resistance temperature signal components to achieve remote, secondary display, it is important to monitor and protect auxiliary temperature. RTD indexing table offer, since the force measuring instrument indexing table thermal resistance, heat resistance indexing table provides the force measured by the Shanghai Automation Instrumentation Co., Ltd. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Since the force measuring device leadership with the staff warmly welcome all inquiries negotiations to create the force measuring instrument since a better future.
