Product details
SupField W series temperature instrument
RTD is divided into three categories: platinum resistance, copper resistance, and nickel resistance. It is based on the characteristic that the resistance value of metal conductors increases with temperature for temperature measurementThermocouple TC is a circuit composed of two conductors with different compositions connected at both ends,
When the temperatures of two junction points are different, an electromotive force is generated in the circuit, which is called thermoelectric potential. The magnitude of thermoelectric potential is only related to the properties of the conductor material and the temperature difference between its two ends.
The integrated temperature transmitter consists of a temperature transmitter and a thermistor or thermocouple, which directly converts the temperature signal into a two-wire (4-20) mA signal and supports HART communication and LCD/LED display.
A bimetallic thermometer uses a bimetallic strip as a temperature sensing element, with one end of the bimetallic strip fixed and the other end connected to the indicator pin as a free end. The connection point shifts with temperature changes and drives the pointer to rotate to indicate the temperature.
Bimetallic thermometers are suitable for measuring medium to low temperatures on site, and can directly measure the temperature of liquid, steam, and gas media within the range of -80 ℃ to+600 ℃ in various production processes.
Thermistors, thermocouples, integrated temperature transmitters, and bimetallic thermometers are used to measure the surface temperature of liquids, vapors, gases, and solids within the range of (-200~1600) ℃. Generally used in conjunction with display instruments, recorders, regulators, PLCs, and DCS systems.
