Frequently Asked Questions
Yes, it’s possible to extend the cable within the limits appearing on the table shown here below:
PTC1000, 2 wires x0.35 sqmm: up to 20 m without compensation
NTC, 2 wires x0.35 sqmm: up to 20 m without compensation
Pt100, 3 wires x0.24 sqmm: self compensation
TC: self compensating special cable
Transmitter 0..1V: up to 10 m
Cables must never run together with leads carrying large currents.
Conventionally this inscription is used to indicate the maximum switchable currents. For example, with what we indicated above we mean that for a load working at 240Vac the maximum current is 8 Amp. if purely resistive and 3 Amp. If inductive, as in the case of an electrical motor.
In many of our instruments there are several adjustments that generate this phenomenon, among these the slowdown parameter and the display offset. Such settings have got the aim to simulate the product temperature on the display, although the probe measures the air temperature. In some cases, as for example in the CDC123, there’s also a third probe designed for the display and it’s different from the thermostat probe.
