Temperature instrument selection, for example (1) temperature control. Temperature control range of 300 ℃ ~ 1000 ℃, 380V three-phase resistance wire heating, power of 50kW, requirements volatility around 5 ℃. K even suggested the use of two digital display measurement and control instruments, the range is 0 ℃ ~ 1200 ℃ pressure table, resolution 1 ℃, relay hysteresis 1 ℃ ~ 2 ℃. Range of motion control contact is ± (1 ~ 2) ℃, plus the furnace temperature measurement lag, basically furnace temperature fluctuation can be controlled within the desired range. (2) oven temperature. Requirements for temperature measuring range of 100 ℃ ~ 400 ℃, 220 V single-phase resistance wire heating, power of 3kW, temperature stability required to achieve ± 0.5 ℃. By temperature stability index, use digital control thermostat can not meet the requirements. Optional TMC300 Temperature Monitor (Shenyang Academy of Instrumentation Science production) or other similar products. Instruments using resistance as the temperature sensing element molybdenum pressure table prices, and control temperature range -50.0 ℃ ~ 600.0 ℃ pressure table cheap wholesale, resolution 0.1 ℃, the measurement accuracy of 0.2% marked differential pressure gauge, control the use of continuous adjustment account air ratio. 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. Bend or tilt installation temperature if a component is installed in the pipeline should be going against the flow. Bimetal thermometer ≤DN50 pipeline or RTD, thermocouple mounted 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, in order to offset the effects of the 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.
