What is the hysteresis?
Two-point control switches the output on or off depending on the deviation form the set point. This means that the output can frequently change with the smallest temperature changes. This can shorten the service life of the output relay and it can ha ...
moreWhat are 2-, 3- and 4-wire circuits?
They describe the number of wires with which the measuring resistor (e.g. a Pt100) is connected. While with the simplest 2-wire connection, the lead resistance can falsify the measuring result, this negative influence can be compensated within the 3- ...
