Introduction JHSK-8H near-infrared line moisture measurement and control instrument can be non-contact online measurement of moisture in coal, sand, ore, etc., the distance between 20CM-40CM, high accuracy, wide range, and provide a 4-20mA current signal for automated control. The main features of non-contact and fast response stable, high precision easy to install, easy to operate near-infrared moisture measurement and control instrument features: fast: the use of long-life high-speed brushless motor, imported high-response infrared sensors, information processing chip FPGA + DSP + ARM9 combination, to ensure real-time data collection, improve measurement precision and stability. Reliability: Double optical detectors, optical system for monitoring and compensation, to ensure moisture measuring sensor from the effects of aging. Technical parameters Measuring range: 0-99% measurement resolution: 0.01% measured distance; 20-40cm illumination diameter: 10cm upper and lower control: Users can develop on the lower limit alarm according to actual needs, can provide binary (non-standard) Current Signal: 4-20mA (standard) computer interface: 485, can be uploaded to a computer, the implementation of testing, printing, storage (non-standard) Power supply: 220V Operating Humidity: 90% or less of the gross weight: 17KG Packing size: 540 × 445 × 450
