ML-020S-I Lux Sensor

The ML-020S-I illuminance sensor is an all-weather sensors with a customized detector sensitivity for indoor low light level or outdoor high light level applications. The built-in interference filter in conjunction with the detectors spectral response reproduces the CIE photopic curve and gives a calibrated output in lux (lx). Both sensors can be found in many professional applications to control or monitor industrial processes.

The low output Voltage of the sensor can be easily converted to a 4-20mA current or higher Voltage using the MS-4..20mA converter. The mV/mA converter can be pre-programmed and optimized within the operating range compatible with common measurement equipment.
