Fusite and Therm-O-Disc were both founded in the 40s with innovation at their core—Therm-O-Disc with the invention of an ingenious bimetal disc and Fusite with their one-piece hermetically sealed feedthrough. These companies continued to create and expand, coming together in 1972.

Our company grew over the decades, adding new brands and product lines by acquiring Microtemp in 1983, Thunderline Z in 2000 and Pactrol Controls in 2018. Through our company’s impressive expansion, the original brands and their names remained—united by a shared commitment to innovation and quality.

In 2023, our name changed, too. Sensience was born, an homage to our dedication and passion for advancing the technology of sensing. It’s a name that represents our determination to help our customers elevate their safety, enhance performance and ensure mission-critical protection.

Today, we are a global manufacturer of highly engineered sensing and control components, delivering the technologies, capabilities and creative solutions our customers rely on.

By strengthening connections through heightened sensing, we’re helping to build a safer, more sustainable future.
