Fig.: Pt100 in 3-wire connection Pt100 in 3-wire connection The influence of the lead resistance is compensated to the greatest possible extent with a 3-wire connection. The requirement for this is that the lead resistances are the same, as can be assumed with a 3-wire connection. The ...
Contact Now This is a platinum analog of RTD that contains 3 wire connected to each other. This design is used most commonly in industries because of greater accuracy. The three-wire connection nullifies the errors associated with one and two-wire connections....

The measuring circuit of signal conditioning module of platinum resistance temperature sensor detection system uses a sub-three-wire connection mode. It can improve the measurement accuracy and reduce the measurement error caused by the external circuit. The amplifier circuit is an operation circuit ...
The Pt 100 thermostat TR600 is a temperature controller and monitors up to six Pt 100 sensors at the same time. Six switching points and six relays permit almost any combination of switching action. It also can select the highest temperature of a group of three or six sensors. The temperatu...
