1Overview

OSA-4AThe illumination sensor is a practical product with a variety of illumination measurement ranges and signal output types that uses a highly sensitive photosensitive detector and a high-precision linear amplification circuit. It is rigorously tested and accurately produced.The sensor housing is designed in the shape of a wall-mounted installation or an outdoor radiation shield. It has a refined structure and beautiful appearance. It is an illumination measurement product with a wide range of applications and extremely high cost performance.2Features（1) adopts imported sensor design, making the measurement more accurate and reliable.（2) High cost performance, wide voltage design.（3)Digital linearization correction, high precision and high stability.（4) is calibrated using real sunlight to minimize the impact of the light source.（5) Flexible installation and easy to use.（6) Small size, light weight, and anti-vibration.（7) can be made into a variety of shapes to meet the needs of different customers.3Scope of applicationIt is widely used in weather stations, agriculture, forestry, greenhouses, breeding, construction, laboratories, urban lighting and other fields that need to monitor light intensity.4Technical DescriptionIllumination is a unit that reflects the intensity of light. It is generally defined as the illumination per unit area (m²) the luminous flux on. The unit of illumination is lumens per square meter (Lm）,Also known as Lux (Lux）。1The illumination of units is approximately1There is a candlelight1meter distance. In our country, under normal circumstances, the illumination under strong light on a sunny day in summer is10Ten thousandLux（3～30Ten thousandLux), the illumination on a cloudy day is1Ten thousandLux, the sunrise and sunset light intensity is300～400Lux, the indoor fluorescent lamp illumination is30～200Lux,at night0.3～0.03 Lux(under the bright moonlight),0.003～0.0007 Lux(dark night).5Technical ParametersMeasurement parameters: light intensityUnits of measurement:LuxOperating temperature:-30～70℃;humidity:0～100.0%RHMeasuring range:0～2/20/200kLuxAccuracy:±3％FSResolution:10LuxNon-linear:≤0.2％FSoutput signal:A:Voltage signalB：4～20mA(current loop)C：RS485(standardModbus-RTUProtocol, device default address:01）Supply voltage:5～24V DC(When the output signal is0～2V，RS485hour)12～24V DC(When the output signal is0～5V，0～10V，4～20mAhour)Stabilization time: after power on1SecondResponse time:<1SecondCable specifications:2rice3Wire system (analog signal);2rice4Wire system (RS485) (cable length optional6Precautions for use（1) When receiving the product, please check whether the packaging is intact and check whether the sensor model and specifications match the product you purchased.（2) The installation location should be away from chemically corrosive environments.（3) Sensors and wires should be kept away from high-voltage electricity, heat sources, etc.（4) The sensor is a precision instrument and should be stored in a dry, ventilated and room-temperature indoor environment.（5) The sensor is a precision device. Users should not disassemble it by themselves when using it to avoid product damage.7Product warrantyThe warranty period of this product is one year. Within twelve months from the date of shipment, our company will be responsible for free repair or replacement of any failure caused by sensor quality problems (non-human damage). After the warranty period, only the cost will be charged.
