KEY FEATURES

OUTSTANDING FIBER OPTIC TEMPERATURE SENSING SOLUTION FOR HERO/RADHAZ APPLICATIONS

Versatile & User-Friendly GUI

To offer a complete solution, the RadSens goes beyond just plain measured data by providing valuable results presentation and data analysis.

Measurements can be displayed in line graph format where each EED monitored is shown with a different color line plot for efficient data comparison. Measurement results can also be displayed in bar graph format showing signal peak levels and identifying problematic assemblies with a user-adjustable alarm level indicator.

Results are available in different user-selectable output measurement units: Absolute and relative temperature (°C or °F), milliampere (mA), microwatt (µW), and decibel below the NFT point (dB).

Useful Integrated calibration tool

The RadSens offers a complete calibration solution to easily and efficiently calibrate instrumented EED. The option includes an embedded current source, available in either 150 mA or 800 mA. The calibration software is fully automated and provides consistent instrumented EED calibration with a minimum of effort and risk of error.

Opsens offers an easy to use full-featured system providing exceptional accuracy

Unique Advantages

RadSens

Easy mounting capabilitiesOpsens’ specially designed adaptor offers easy mounting capabilities on common EEDs. It solidly holds the OTG-R optical fiber to perfectly position the tip on the EED device. This set up provides the required assembly robustness for the most difficult applications.

Different geometry availableOpsens’ skill and knowledge in fiber optic sensor packaging assures that sensor geometry will fit any special bridge wire designs. The above picture on the right shows a side-looking sensor for a bridge wire coil.

Opsens’ Fiber Optic temperature sensing solution for HERO/RADHAZ applications provides accurate and reliable assessment of Electromagnetic Environmental Effects on ordnance. The products behind this solution are the RadSens innovative signal conditioner packaged with key integrated functionalities and the OTG-R fiber optic temperature sensor specially designed for bridge-wire type electro-explosive devices.

Recognized as a reference Superior technical features and ease of use make the RadSens system the reference solution for electromagnetic compatibility testing and assessment of bridge-wire electro-explosive devices (EED). The RadSens has rapidly become a must have for HERO testing in Army, Navy and Air Forces all over the world. Among others, the RadSens system received the U.K. Defence Ordnance Safety Group (DOSG) approbation.

The only all-in-one instrumentation you will need:

Much more than a measuring toolFully integrated solution• On-board computer for real-time data acquisition• Built-in GUI with touch screen display• Embedded data storage for local data management • Real-time data filtering and analysis• Ethernet interface for PC remote control

Designed with the Hero/RADHAZ needs in mindThe RadSens system produces more than real-time temperature measurements. It can automatically convert temperature measurements into meaningful units for the Hero/RADHAZ tester: Milliampere, decibel below the No-Fire-Threshold and microwatt. These measurements can be displayed in various numerical and graphical formats.

OTG-R Sensor

Smart & precise measurementsEasy CalibrationThe RadSens offers a built-in automatic calibration feature. No more need for collecting and analyzing data manually. The EED induced current sensitivity is automatically calculated using the software provided with the system. This unique feature can reduce calibration time by up to 90%.

Advanced FilteringThe RadSens system comes with a unique and innovative high performance adaptive filter for signal noise removal. Without any compromise on response time, the filter remains very efficient even when faced with fast signal variations and this, with minimum attenuation of the signal high frequency components.
