Industrial interfaces take both touch and pressure inputs

At Hannover Messe 2015, Peratech is to demonstrate its touch screen industrial controller relying on the company's standard keyboard sensor featuring Opaque QTC (Quantum Tunnelling Composite) force-sensing technology.

The sensor accurately measures both the amount of pressure applied to the keypad and its precise location, at a better resolution than today’s capacitive touch screen technology. As an integral part of a total HMI (Human Machine Interface) solution, QTC technology is said to offer many advantages over capacitive and other existing touch solutions – greater safety, greater accuracy, better consistency, and higher reliability, in a cost effective solution with low EMI, power, and size constraints.

Operational at temperatures lower than -20ºC and higher than +60ºC, the QTC technology can work behind a variety of surfaces including glass, metal or plastic, and it uses less processing power compared to projected-capacitive solutions. The overall power budget is also less with a QTC-based solution as it only requires power when touched, unlike capacitive that always has its sensing field powered up and thus draining the battery life, claims Peratech.
