① temperature of the installation location should be selected first point in the medium temperature sensitive and representative place, should not be selected in the vicinity of the valve and the media stream, welds and other parts of the resistance was dead place. Indicating thermometer to be installed in place to facilitate the observation of the place. Thermocouple installation site should stay away from magnetic fields. If the temperature of a component mounted in the corner or inclined pipe installation temperature table ch013, should be against the flow direction. Bimetal thermometer ≤DN50 pipeline or RTD, thermocouple temperature meter installed on ≤DN70 pipeline to expand the pipe installation. Expand the pipe according to the standard map production (see Chapter 10). Pressure thermometer bulb must be completely immersed in the test medium. ② temperature to be supporting the use of the second table. RTD, thermocouple to be equipped with the appropriate secondary table or transmitter. Pay particular attention to sub-degree, different indexing table numbers can not be misused. ③ thermocouple wire must be compensated by the corresponding number of indexing. RTD should adopt the three-wire connection rdc temperature controller, to offset the impact of ambient temperature. Each table has its own secondary external circuit resistance requirements, in addition to line resistance compensation wire or cable, they also need to use manganese copper coupled with the corresponding resistance to meet the requirements for secondary table. Control methods are generally divided into two types; one is cooled by the temperature change is subject to control ptc100 temperature table, the use of vapor pressure temperature controller, another object to be cooled by the temperature change is to be controlled, and more The electronic temperature controller. Thermostat is divided into: mechanical divided into: vapor pressure thermostat, liquid expansion thermostat, gas adsorption thermostat, metal expansion thermostat. Where the vapor pressure thermostat is divided into: inflatable type, liquid gas and liquid-filled hybrid type. Household air conditioners are in such a mechanical thermostat based. Electronic divided into: resistance and thermocouple temperature control thermostat. magnehelic temperature table wholesale | Rugao temperature table | Li gifted Litas established by Changzhou gifted Litas Electrical Co., Ltd.
