Whether custom designed to fit a customer's specific needs, or one of our proven off-the-shelf solutions, our line of speed and temperature sensors are perfect for everything from high altitude, high performance aircraft to ground-based turbine and industrial applications.

Unison sensors are made rugged enough to withstand temperature and vibration extremes, stable enough to withstand high overpressure and pressure transients, and sensitive enough to provide accurate controls. Sensor types include temperature-sensitive fluid-filled bellows assemblies, Type K or E thermocouples, Resistance Temperature Detector (RTD), and magnetic speed sensors. From prototype to production, Unison has custom solutions for even the most demanding sensing requirements and budgets.
