The stainless steel NTC temperature sensor is an NTC (Negative Temperature Coefficient) thermistor temperature probe enclosed in a stainless steel housing. It combines the high sensitivity of the NTC thermistor with the excellent mechanical strength and corrosion resistance of stainless steel, making it a durable temperature sensing device widely used in complex industrial environments. Its core operating principle is to accurately detect temperature by measuring the change in resistance, which decreases exponentially with increasing temperature.

PTC thermistors are electronic components whose resistance increases significantly with increasing temperature. They exhibit self-healing properties, rapidly switching to a high-resistance state in the event of overcurrent or overheating, automatically disconnecting the circuit. They also automatically reset themselves after the fault is resolved. They are widely used in circuit protection, motor starting, and temperature sensing.

K-type thermocouples are among the most widely used contact temperature sensors in industrial, commercial, and consumer heating systems. The units in the image are designed for reliable, high-accuracy temperature measurement across a broad range of operating conditions, from low ambient temperatures to extreme heat environments.

In inverter welding machines, the core function of a PTC thermistor is to act as an inrush current suppressor. Connected in series in the welding machine's power input circuit (before the rectifier bridge), it protects key components such as the rectifier bridge, filter electrolytic capacitors, and switching transistors (MOSFET/IGBT) from being damaged by the huge inrush current generated by capacitor charging during startup.
