Technical Data Description
Operating temp: - 20 ...+   60 degree C The refractive index sensor has a built in LED source.  Light refracted in a liquid is analyzed and the refractive index is calculated as a difference. For instance, the sensor lights up an LED which is externally visible when X% of water is in the diesel.  Some applications may need calibration.  Due to the sensitivity and high sample rates it is advised that the sensor be mounted firmly avoiding any environmental light.  
- 04 ...+ 140 degree F
Weight:    7 oz (.2 kg)
Protection: IP 54, NEMA 3
Housing: Plastic
Humidity: Up to 98% permissible
Indicator: LED Comparative measurement mode
Connections To hold a specific surface finish, the sensor output can be compared with a previously obtained one. This will provide monitoring of the refractive index during a technological process. The previously obtained sensor output is taken on    a “template” liquid that meets quality requirements.

Aside is a sample graph showing the sensor output versus the refractive index.  Note that the output shown across is not typical and varies for different materials and machining processes.
Ways to Hook up Device
1. It can be mounted directly onto vehicles by connecting the power to the 12 Volt battery and ground to the chassis.
2. Hazardous areas stationary 24 Volt powered with barriers
3. Stationary 24 Volt powered
4. External LED (for external warning)
