K J E T PT100 RTD type Multicore thermocouple compensation cable extension wire

Thermocouple cable is the extension wire for the thermocouple and RTD.It cost low and abroad application in plastic,food,packing industrial.

Notes for use:

1. Selection for Compensating Cable

The product must be chosen in line with the type of the used thermocouple and the application occasion. For instance, the K type thermocouple should be assorted with the K type compensating wire. Confirm the working temperature range according to the application occasion. Generally, the KX type product works with the temperature of -20°C to 100°C and a wider temperature range of -25°C to 200°C.If you want to choose the insulation material or shielding layer, please refer to the Customer Selection Chart on the page.

2. Contact Connection

Make the two contacts of the thermocouple terminal as close as possible to try to keep consistent temperature of the two contacts.

Meanwhile, keep the connection points of the instrument terminal having consistent temperature as much as possible. The contact needs protection from being blown directly by the fan of the instrument.

3. Using Length

The signal of the thermocouple is very slight with microvolt level. So, if the compensation cable is too long, the attenuation of the signal and the interference coupling of the strong current in the environment can cause signal distortion of thermocouple definitely. Then the measuring and temperature controlling are not correct. If serious, the temperature fluctuation would come out.

In line with our experience, the length of the thermocouple compensating wire should be controlled within 15m.If it exceeds 15m,the temperature transmitter is recommended for transmitting signal. It transforms the electric potential value of the corresponding temperature into the direct current to transmit, featuring strong anti-interference capability.

4. Wire Arrangement

The arrangement of the thermocouple cable must stay away from the power line and interference source. The crossing mode rather than the parallel mode should be adopted as much as possible in the case of unavoidable traversing.

5. Shielding the Compensating Wire

The method of shielding compensating wire can be employed for enhancing the anti-interference capability of the thermocouple connecting wire.It can get better effect especially in the case of the occasion having lots of filed interference source. But there is a prerequisite of grounding the shielding layer strictly. Otherwise the shielding layer would lose the shielding function and also enhance the interference.
