LUX illuminance sensor
- Manufacturer: Nesa
- Category: Meteorology – Climatology, Solar radiation - Light, SENSORS
The NESA LUX is an indoor/outdoor (IP67) illuminance (lux) sensor with a silicon photodiode whose spectral response matches that of the human eye (standard photopic curve V(λ)). Three selectable ranges: 0.02 ÷ 2 klux, 0.2 ÷ 20 klux, and 2 ÷ 200 klux.
Output 0-10Vdc or 4-20mA. Supplied with a 5m cable and calibration report. For offices and laboratories, industrial buildings, shopping centers, theaters, museums, sports facilities, roads, tunnels, and nurseries.
Key points
- Ranges 0.02 ÷ 2, 0.2 ÷ 20 or 2 ÷ 200 klux
- Sensitivity 5-500 mV/lux, accuracy < 8% with respect to V(λ)
- Silicon photodiode, photopic curve V(λ)
- Output 0÷10Vdc or 4÷20mA
- IP67, -20 ÷ +60 °C, < 200 g
Technical Frequently Asked Questions
What are the measurement ranges of LUX?
Three, to be indicated in the order: a) 0.02 ÷ 2 klux, b) 0.2 ÷ 20 klux and c) 2 ÷ 200 klux.
What exits does it have?
LUX-A: 0÷10Vdc, with a 16 ÷ 30Vdc power supply. LUX-B: 4÷20mA, with a 10.8 ÷ 30Vdc power supply.
How do I order it?
Sensor (LUX), range (a, boc), output (A or B), sensor-datalogger cable (05, 10 or xx, length in meters to be specified) and SSU support of L = 700-750 mm. Manufacturer example: LUX b B 10 SSU.
