Thermocouple cold junction is too close to the furnace so that the temperature exceeds 100 ℃; thermocouple should be installed as far as possible away from strong magnetic fields and strong electric field, it should not be the thermocouple and power cables in the same wire-bound to introduce a catheter to avoid interference caused by error; Thermocouples can not be installed in an area rarely measured medium flows sheathed thermocouple, when used in the gas temperature thermocouple measurement, you must install the thermocouple against the direction of flow sheathed thermocouple manufacturers, and full contact with the gas. 1.5 Insulation resistance (insulation resistance) offer for thermocouple sheathed thermocouple having a pair of hot electrodes, the thermal resistance of the electrode finger between the value and the protection tube; for thermocouple with multiple electrodes to heat, also means that each of the hot electrode resistance values. 1.6 thermal response time (thermal response time) when the step change in temperature, change in the output of the thermocouple to the time corresponding to the step change to a predetermined percentage of the desired, generally τ expressed. Sheathed thermocouple Quote | force measurement since the instrument quality assurance (certified) | Shaanxi sheathed thermocouple measured by the Shanghai Automation Instrumentation Limited. 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.
