TEMPERATURE SENSOR FOR SOLAR PANELS! The best, most durable reliable - max. 250 x C ! . Because this sensor has a teflon insulated connection cable, it has a high upper application temperature. It is therefore resistant to temporary temperature spikes well above 200 or even 250 x C. Sensors with a silicone insulated cable (up to 180 x C) are usually used in such systems, much more susceptible to high-temperature damage. There are also manufacturers using wires in insulation with PCV (! ) This should be treated as a misunderstanding! The cable in Teflon insulation is also incomparably more resistant to mechanical damage. CO.KT 6/50/SS-1000 Pt1000 kl.B Temperature sensor with resistor Pt1000 kl.B by. PN-EN 60754. Connection cable, two or four-core cable 2x0,24 in Teflon insulation. The length of the cable in the basic version - 1 meter. The maximum operating temperature is 250 x C. The cover is made of stainless steel 304 The length of the cover - 50 millimeters. Cover diameter - 6 millimeters.

( NTC10K sensor or NTC2K2sensor) If it is not a Pt1000 sensor, it may be a np sensor. type NTC. The sensor type should be specified in the controller manual. Sensor connection cable length : If you need a sensor with a longer cable, you have to pay 14 zlotys for each additional meter. The corresponding amount can then be paid. NOTE : It has a connection cable in silicone insulation and therefore a lower maximum temperature of use. This is also a good solution but the sensor is softer and more susceptible to damage.
