Note
It is not necessary to calibrate the line with temperature sensors with Pt 1000 resistors. In cases where the length of line between
sensor and controller exceeds 100 m, the cross-section of the wire must be at least 1.5 mm². Route the sensor lines and othersupply voltage lines separately.
The Type 5267-3 Contact Sensor is suitable for pipes with up to 60 mm diameter. On assembly, the supplied heat-conducting
paste must be applied between the sensor (copper protective tube) and the pipe.
The maximum permissible wire cross-section is 1.5 mm² for terminals for sensors (Types 5227-4, 5257-xx and 5267-3).
