ML-020S-I Lux Sensor (MTI.AWS.EK.020S-1) illuminance sensor is an all-weather sensor with a customised detector sensitivity, optimised for indoor low light level or outdoor high light level applications. In conjunction with the detector spectral response, the built-in interference filter reproduces the CIE photopic curve and gives a calibrated output in lux (lx). 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 optimised within the operating range compatible with standard measurement equipment. Together with the MS-020S-O Lux Sensor, the ML-020S-I is often deployed in professional applications, controlling or monitoring industrial processes.
