Ametherm recently announced its ability to completely customize the company's offering of NTC thermistor probe assemblies to meet the specific needs of any application. Designed and built in as little as two weeks, the units are the ideal choice for high-accuracy temperature sensing and measurement for IGBT chips and heatsinks in welding equipment, plasma cutters, air sensors, electric motors, and HVAC systems.
Ametherm's NTC thermistors are manufactured from a specially formulated metal oxide ceramic material that is extremely accurate in sensing temperature. Utilizing this same material, the company's custom probe assemblies are available in a variety of housings - ring terminal, flag terminal, steel tube, threaded hex, and threaded long tip - and lead wire gauges and insulation thicknesses. Ametherm can build the devices to customer-specified resistance values, tolerances, beta values, insulation resistance, and dielectric voltage breakdown.
"We can customize our probe assemblies in any way the customer wants - including matching or creating any resistance temperature curve - and we offer the highest isolation voltage available," says Eric Rauch, president and CEO of Ametherm. "The key to making custom probes is to have all the requirements up front, so listening to the customer is imperative. Equally important is flexibility. In some cases three or four design changes will be made, but in the end we create a device unique to each customer that can suit their needs better than an off-the-shelf solution."
