XIQI Electric CG-ZC K-Type Thermocouple Sensor - 4x30mm Stainless Steel Probe, 1m Shielded Cable

This sensor typically features bare, tinned wire leads at the end of the 1m shielded cable. These leads are designed to be connected directly to screw terminals on a temperature controller, PLC analog input module, or a thermocouple transmitter. Always ensure proper polarity (positive and negative leads) when wiring to a compatible K-type input.

Extending thermocouple cables requires careful consideration. Using standard copper wire will introduce measurement errors. For extensions, you must use thermocouple extension wire of the matching type (K-type) and ensure all connections are thermally stable and secure to avoid creating unwanted parasitic junctions that affect accuracy.

Thermocouples, like this K-type model, generate a small voltage based on temperature difference (Seebeck effect) and are suitable for wider temperature ranges (-200°C to 1350°C for K-type). RTDs (Resistance Temperature Detectors) change electrical resistance predictably with temperature and generally offer higher accuracy and stability over a narrower range. The choice depends on required temperature span, accuracy, and system compatibility.

Yes, the stainless steel probe is corrosion-resistant and can be immersed in non-aggressive liquids within its 0-600°C range, such as in tanks or baths. Ensure the installation method (threaded fitting, compression gland) provides a proper seal. The probe is not pressurized, so it is not designed for high-pressure vessel applications.
