New NTC thermistor probe assembly for Li-ion batteries

Louise Smyth

Ametherm has introduced a new NTC thermistor probe assembly for high-accuracy temperature sensing and measurement in Li-ion battery power applications. The device combines a specially designed ring lug for battery mounting with a high dielectric voltage rating of 4000 VAC.

Ametherm's NTC thermistors are manufactured from a specially formulated metal oxide ceramic material that is extremely accurate in sensing temperature. The PANR 103395-342 probe assembly utilises this same material while offering a half-inch stud-insulated ring lug that enables easy and secure mounting to Li-ion terminals.

Providing a high-stability replacement for less-accurate thermocouples, the PANR 103395-342 experiences minimal drift from its initial electrical values. The device offers resistance at 25°C of 10 kΩ, beta of 3950°K, dissipation constant of 8mW/°C, thermal time constant of 10.0s, and an operating temperature range of - 50°C to + 180°C. The RoHS-compliant assembly features 18-AWG stranded Teflon-insulated lead wires.
