Integration of intelligent explosion-proof digital display integrated thermocouple thermocouple output 4-20ma

Integrated temperature transmitter is a temperature sensor and a signal converter composed of the signal converter is installed at the cold end of the temperature sensor junction box, the temperature sensor affected by temperature resistance or potential effect generated by the conversion produces a differential voltage signal. This signal is amplified by the amplifier, and then the voltage and current signal conversion, output and span corresponding 4-20mA or other 0-5V / 0-10V signals. Integrated temperature sensor element temperature transmitter (RTD or thermocouple) and signal conversion amplification unit were integrated to measure liquid, vapor and other gases in the various processes in the range -200-1600 ℃ temperature of the medium or solid surface. It usually display instruments, recording instruments and supporting the use of various control systems. It has a simple structure, installation, use, and easy maintenance features, has been widely used in petroleum, chemical, metallurgy, power, light industry and other sectors. MCT80Y series integrated temperature transmitter is divided into ordinary type, explosion-proof digital display integration categories. Among them, the ordinary type and flameproof can choose different built-in temperature transmitter modules to meet the application requirements of different users. Temperature Transmitter by temperature sensors, thermocouple and RTD is divided into two ranges. Main features: two-wire transmission. Signal converter powered two wires at the same time is also transmitted signal output signal output current or constant voltage signal, anti-interference ability, good remote performance. Signal converter uses epoxy resin into modules, with anti-vibration, corrosion, moisture, etc., it can be used for disadvantaged areas. Thermocouple millivolt signal by the signal converter is directly converted into 4 ~ 20mA current output, with ordinary cable transmission signal, eliminating the need for expensive compensation wire. Temperature Transmitter with live display of both output 4 ~ 20mA current signal, but also the actual temperature reading in temperature field, bring great convenience to the operator. High precision, interference, long-term stability, maintenance-free, can be remote (most far 1000 m). Technical Specifications: Range: -200 ~ 1800 ℃ conventional precision: ± 0.25% Supply voltage: 13 ~ 30V, DC load resistance: 0 ~ 850Ω output signal: 4 ~ 20mA Basic error: ± 0.2%, ± 0.5% Display: LCD Display the ambient temperature: 0.25% / 10 ℃ cold junction compensation error: 0.5% / 10 ℃ Explosion-proof mark: dⅡBT4 Protection: IP65 Input type: RTD, Pt100, second- or third-line thermocouple (all known types) Ambient temperature: -40-85 ℃, with display type is -10-70 ℃ Humidity: 0-95% RH, non-condensing Display Options: pointer table or digital LCD display Optional protection tube material: 1Cr18Ni9Ti or ceramic or steel-tube wiring and adjust: transducer system connected as shown, 24VDC power supply to the transmitter via a shielded cable, "V +" positive connection with 24VDC, "V-" then negative, to standard output 4-20mA transmitter repeatedly adjust zero and span potentiometers when the signal source (resistor box or millivolts), the signal source is given zero and full scale signal can be accurately adjusted range. When the "Z" for the zero adjustment potentiometer, "S" for the full-scale adjustment potentiometer (all potentiometers are in the factory before the school is good) use, due to line resistance, temperature and other factors which cause the error affected only fine-tuning Zero potentiometer "Z" can be corrected. The calibration method can also be used to correct systematic errors. Description: General Power voltage Vs choose 24V, load resistor RL selection 250Ω, so when the loop by 4 ~ 20mA current, voltage drop on RL 1 ~ 5V. If you choose another value Vs and RL, then RL value can not exceed the formula RL = calculated value.
