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,” said 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.”
“Ametherm customers utilize our custom probe assemblies in a variety of applications,” said Mehdi Samii, vice president of engineering at Ametherm. “Their use in monitoring the temperature of heatsinks and circuit boards is critical to thermal management in power supplies, motor drives, and HVAC systems. For welding equipment and plasma cutters, their small size and close proximity to IGBT chips allows for faster, more accurate temperature readings and higher chip performance. Whatever the application, we can create the perfect device to deliver the accuracy you need.”
