Compensation wire is divided into two kinds of compensation type and extend, extension wire chemical composition and compensated thermocouple same three-wire RTD wholesale, but in practice three-wire RTD, extending type thermocouple wires are not used and the same metal material, commonly used and thermocouple wires instead of the same electron density. Compensation wire thermocouple wires are generally very clear, positive connection compensation wire thermocouple red line, and the negative is connected to the rest of the colors. Most of the general compensation wire materials are copper-nickel alloy. Industrial heat resistance generally use Pt100, Pt10, Cu50, Cu100 three-wire RTD retail, platinum RTD temperature range of minus generally 200-800 ℃, copper heat resistance is minus 40 到 140 ℃. RTD and thermocouple type the same distinction, but he did not need to compensate for the three-wire RTD lead prices, but cheaper than the thermocouple. Many installation in the form of platinum thermal resistance, a fixed threaded mounting, activities threaded mounting, mounting flange, flange mounting activities, events fittings installed, install straight pipe joints and so on. Three-wire RTD retail _ _ three-wire RTD force measuring instrument lowest since the force provided by the Shanghai Automation Instrumentation Co. measured. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the force measured since the instrument into the brilliant and you work for a better future!
