The resistance value of the Pt100 connection cable must be taken into consideration as of a length of >3 m / 9.8 ft, when aligning the measured value.
The TF-M-Atex/TF-E-Atex series consists of simple electrical equipment without a separate voltage source. In the case of intrinsically safe connections as per EN 60079-11, the TSA-Atex can be used in Zone 1 (group IIC, device category 2G) explosive areas; this also applies to the inner zone of the tank. The temperature switches are classified into temperature class T4.
The design of the temperature switch was chosen, to enable the removal of the electrical inner workings without having to remove the switching tube from the tank. This is convenient if the temperature switch is installed externally underneath oil.
