The PMA4100 Series CALReady™ Photostability sensors are process control sensors that have the capability of being calibrated in the field by the end user.

The PMA 4100-420 sensor System has two sensor types, the PMA 4110-420 UVA sensor and the PMA 4130-420 Photopic sensor.  The sensors detect light from their respective spectral bands and send a current proportioned signal on a 4 – 20 mA current loop.  The PMA 4110-420 sensor is sensitive to the 320 – 400 nm spectral band and has a maximum (20 mA) sensitivity of 1.000 W/cm².  The PMA 4130-420 sensor is sensitive to the CIE Weighted Photopic spectral range, 480 - 620 nm, and has a maximum (20 mA) sensitivity of 5000 Lux. 

This CALReady™ sensor system includes reference sensors, transfer calibrated from NIST traceable standards. One Reference sensor is available to calibrate the Process sensor for the Photopic range and one Reference sensor is available to calibrate the Process sensor for the UVA.  The software system can perform an in situ transfer calibration when connected via the USB.
