These 3-pin sensors are capable of measuring force and pressure in environments as hot as 400°F (approximately 200°C). The HT201 measures a standard force of 222 N (50 lb), with a maximum force of 2,224 N (500 lb)*

These ultra-thin, high-temp sensors are ideal for non-intrusive force and pressure measurement in a variety of processing applications, including injection molding, heat sealing, and heat sink applications. Industries that will benefit from such high-temperature force measurements include automotive, aerospace, pharmaceutical, printing, food and beverage processing, and many more.

How to Adjust the Force Range:

*In order to measure forces outside of specified ranges, use recommended circuit and adjust drive voltage and/or reference resistance. For an alternative to the recommended circuit, see the Related Electronics tab.
