How the circuit is configured determines how accurately the sensor’s resistance can be calculated, and how much the temperature reading may be distorted by extraneous resistance in the circuit. Since the lead wire used between the resistance element and the measuring instrument has a resistance itse...
Notes: NTC thermistors are the most commonly used (especially the 10KΩ ntc thermistor) and along with an addition services resistor, Rs can be used as part of a simple potential divider circuit so that changes to its resistance due to changes in temperature, produces a temperature...
Creative built-in design of protection functions such as load short-circuit protection, load circuit break and sensor protection. Other Characteristics Large screen display window is adopted to keep intuitive and eye-catching; Six-digit display is adopted with resolution of 0.001ºC (adjusta...
In this configuration, the errors due to lead-wire resistance, along with temperature variation effects, are removed. Therefore, a 4-wire configuration results in the best performance. RTD Configuration Circuit A high precision and accurate RTD sensor measurement requires precise signal co...
wire resistance can drastically reduce the accuracy of the measurement by adding additional, uncompensated resistance into your system. Most applications therefore add a third wire to help the circuit compensate for lead wire resistance, and thus provide a truer indication of the measured temperature. ...
