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

This sensor is supplied with bare wire leads at the end of the 1-meter cable. It is designed for direct screw-terminal connection to a compatible temperature controller, PLC analog input module, or data acquisition system that accepts bare thermocouple wires. You may need to add a mini thermocouple connector if your equipment requires it.

No. The CG-ZC is calibrated and specified for a standard operating range of 0°C to 600°C. While K-type thermocouples can technically measure below freezing, this specific industrial sensor is not characterized or guaranteed for performance in sub-zero conditions. For cryogenic or low-temperature applications, a specialized sensor is recommended.

Yes, but it must be done correctly to maintain accuracy. Use proper thermocouple extension wire (K-type) and a calibrated junction box to splice the cables. Avoid using ordinary copper wire, as it will introduce measurement errors due to the creation of additional thermocouple junctions at the connection points.

This sensor features a grounded junction, where the thermocouple wires are electrically connected to the metal probe sheath. This provides faster thermal response but can make the signal susceptible to electrical ground loops if the sheath contacts grounded metal. Ungrounded junctions are electrically isolated for noisy environments but have slower response times.
