关于电阻温度传感器的常见问题解答 维连电子紧凑型温度传感器A answers to common questions about resistor temperature sensors
 
Accurate temperature measurement is essential for research laboratories, hospitals, refineries, chemical plants, food manufacturers and pharmaceutical vendors. This is why many laboratories and industrial applications choose a reliable and accurate resistance temperature detector (RTD) as temperature measurement instruments.
 
RTD is a temperature sensor that uses metal resistors to determine temperature changes. The resistance value of the metal wire resistor that constitutes the RTD working component changes with temperature changes. Because the resistance of the metal (usually platinum) wire is known as a known number, it can accurately calculate the temperature change according to the change of the wire resistor.

Can the RTD temperature sensor be used for all applications?
cannot. RTD can only be used at a temperature of about 482–538 ° C. Therefore, high -temperature mining, refining, and similar applications usually use thermocouple temperature measurement system. RTD is usually not used in applications below 93 ° C, because dual metals or expansion thermometers can work with less money.

Can the RTD temperature sensor be installed in a small space?
Yes. Victoria offers a variety of compact RTDs for industrial temperature measurement:
Weiliantr15 These compact temperature sensors are very suitable for processes with difficulty or unable to directly install or manufacture applications, radiation or conduction areas with excessive heat, or applications with significant vibrations.

Is the RTD temperature sensor used in HVAC applications?
Yes. The Villian RTD used for HVAC measures the environment of the environment. These strong and flexible instruments can be used in a humid or dry environment and indoor and outdoor environment. The TR60 RTD series components are usually used to measure the temperature of air -conditioning rooms, refrigerated rooms, warehouses and granary.

Can the RTD sensor be used with the transmitter?
Yes. A variety of temperature transmitters based on RTD temperature sensors, including T15 and T53 -type bus temperature transmitters. Add the transmitter to the RTD sensor to send the temperature data to the remote control position and view it in the local display.
