FAQ

What is the difference between a 2-wire, 3-wire, and 4-wire Pt100 sensor like this TST187-1A3B?

This TST187-1A3B is a 4-wire sensor, which offers the highest accuracy. A 4-wire configuration uses two wires to carry the excitation current and two separate wires to measure the voltage drop across the sensor. This completely compensates for the lead wire resistance, unlike 2-wire (no compensation) or 3-wire (partial compensation) systems, making it ideal for precision measurements.

Can this sensor be used with any standard PLC or temperature controller?

Yes, this sensor uses a standard Pt100 Class A element. It can be connected to any PLC analog input card or temperature controller that is designed for Pt100 RTD inputs. Ensure your controller is configured for a 4-wire Pt100 input to take full advantage of its accuracy.

What does the ‘TF’ in ‘1xPt100/TF/4’ stand for?

The ‘TF’ designation in Endress+Hauser sensors typically stands for ‘Temperature Fast response’. This indicates that the sensor’s internal construction is optimized for a quick response time to changes in temperature, which is crucial in dynamic processes requiring tight control.
