Opsens Solutions’ EMC testing and Electrical current measurement for EED devices

Opsens Solutions offers a fast, robust and high accuracy temperature measurement solution for bridge-wire electro-explosive devices.

The RadSens-type signal conditioners and OTG-R-type fiber optic temperature sensors are unique products specifically designed for Radio and Radar Radiation Hazards (RADHAZ) applications, Hazard of Electromagnetic Radiation to Ordnance (HERO) applications, and Electromagnetic Compatibility (EMC) testing assessment of bridge-wire electro-explosive devices (EED).


A simple but robust spectrophotometric technique, it relies on the temperature dependence of the bandgap of GaAs semiconductor crystal. GaAs crystal is opaque for wavelengths below its bandgap and transparent for wavelengths above it. The transition region, i.e. the bandgap spectral position, is a function of the temperature.

The RadSens solution was designed to provide high level of flexibility essential for HERO applications. Already adopted by major Army, Navy and Air force across the world, the RadSens offers many unique advantages and benefits:
