UCLC "Convertidor Universal de Bucle de Corriente"

                              Puede ser alimentado directamente del HOBO 

The UCLC is a special purpose amplifier that converts the micro-amp level current output of LI-COR light sensors to an industry standard current-loop level. The UCLC can be configured at the factory or by the end user for any one of three standard LI-COR sensors and any one of two popular current loop levels, through the manipulation of two plug-in jumpers. No soldering or other adjustments are required. The UCLC provides a simple interface between LI-COR sensors and current loop signal processing equipment including data loggers, meters, industrial control equipment, HVAC and green house control systems.

 LI-COR sensor  Typical full sun response UCLC output (user selectable) 
 LI190 PAR sensor 10µA @ 2000 µE/m2s 1-5 or 4-20mA @ 0.0-12.5µA in 
 LI200 Pyranometer 100µA @ 1000 W/m2 1-5 or 4-20mA @ 0.0-125µA in 
 LI210 Photometer 40µA @ 100 klux (=9290 ftcd.) 1-5 or 4-20mA @ 0.0-50µA in
.

Alternate settings are available on special order. The calibration tag provided by LI-COR with each sensor in conjunction with the UCLC gain setting can be used to compute the light level incident on the sensor with a high degree of accuracy.

On the UCLC shown in the photo, the input cable from the sensor will enter through the gland nut to the left, and the output cable to the equipment will exit through the gland nut on the right. The UCLC is also available with a BNC connector on the input. The calibration label on the outside of the enclousure is marked with the applicable gain setting. Wiring instructions and calibration notes are included with each UCLC.
