Hot!!! DFP-300 Lever Type Smart Photoelectric Sampler
I. Introduction
DFP300 lever type smart photoelectric sampler owns the advantages of small volume, long service life, high sensitivity, large range adjustment, convenience in operating and strong antijamming capability. It's the ideal photoelectric sensing device and widely used for the testing of accuracy on mechanical and electronic meters.
II. Features
1. Both crossbar and vertical rod adopts the variable length rod, applicable to most single and three phase platform; it is also compatible with reversal pattern.
2. Entire mold production, strong consistency, light weight and durable.
3. Using smart sampling head, be self-adaptive to optical adjustment, real time sampling in place, free reset and adjustment, easy to machine turned.
4. Superstrong adaptability to work environment, light range 0-1000LX.
5. Compatible with mechanical and electric meters, trigger switch, working state memory when power-down.
6. Auto-adaptation to site light-dark cycle, can inhibit the burst-interference of lights and strong AC lights.
7. The maximum sampling frequency is up to 100Hz, minimum sampling frequency is 0.01Hz, can sample 1mS pulse width of imported meter.
8. Ultra-high sensitivity, wide receiving range: 15-60mm, angle adaptation is bigger than 15 degrees.
9. Special single chip design, stable and reliable.
10. Color direction, good visibility.
III. Specifications
1. Working voltage: DC4.5-6V
2. Working current: ≤50mA
3. Power consumption: ≤0.25W (when no load)
4. Sample distance: 25-45mm
5. Output signal: high level≥4.5V (with black mark)
low level≤0.2V (without black mark)
6. Output current: 3mA-5mA
7. Anti-interference: deburring≤3.0mm
IV. Operating Instruction
1. Placing the photoelectric sampler with 25-45mm distance from the right front side of checked meter.
2. Determining the working state through multi-color in the rear side: green color indicates mechanical meter, red color indicates electronic meter.
3. Switching working state: press the red reset button for 1.5 second, then the sampler will switch working state between mechanical and electronic.
4. By adjusting the vertical position to make the beam center irradiate in the disc of checked meter or pulse output light of electronic meter.
5. In right state and position, the photoelectric sampler will take samples automatically, without manual adjustment.
