XIQI Electric CG-WRNT-02 K-Type Thermocouple Sensor, M8 Thread, 1m Cable

The sensor typically terminates in a standard mini-thermocouple connector (often a male plug) compatible with common temperature controller sockets. Please verify the specific connector type against your controller's manual, as pin configurations can vary between manufacturers.

Yes, but it requires an intermediate signal conditioner. The raw millivolt output from a thermocouple must be amplified, cold-junction compensated, and linearized by a dedicated thermocouple amplifier IC or module (like a MAX6675 or AD8495) before it can be safely read by a microcontroller's ADC. Direct connection will not provide accurate readings.

A grounded junction, like the one typically used in this industrial sensor, has the thermocouple wires physically welded to the inside of the metal probe sheath. This provides faster thermal response but creates an electrical connection to the sheath, which can lead to ground loop noise in some circuits. An ungrounded junction is electrically isolated from the sheath for use in noisy environments or when measuring voltages.

The M8 thread provides a robust mechanical seal for most atmospheric and low-to-moderate pressure process environments. For high-pressure or critical sealing applications, you should verify the thread specification and consider using appropriate sealing washers or compounds as recommended by your equipment manufacturer.
