Loop Detector For Sale 

LOOP Detector from Shenzhen Noble OPTO.CO.,LTD, Loop detector install parking lot and Induction Loop traffic detector very intelligent.loop detector price is very cheap and it was our hot sale product item.

Noble of Loop Detector of Product advantages, our loop detector of voltage can make 85-240VAC or 12-24VAC, other factories of voltage only do  220v or 110v, 12v or 24v. our loop detector models of Loop Inductance, Ideal 25µH to 1000µH, max: 20µH to 1200µH, Sensitivity △L 0.01% to 2.56% with 16selectable, applicative traffic control applications toll systems vehicle counting traffic analysis

Loop detector for sale product testing method,loop detector Use the same sensible coil (any sensible quantity within the standard) to connect to the original and developed products, placed under the motor rotor blade, loop detector test at the same distance and in the same environment, adjust the motor speed to the maximum, startup, turn off the motor when the motor rotates Slowly reduce the speed from high speed. When the motor drops to a certain speed, the sense detector starts to detect and send a signal, and the A and B relay work. The A and B relay input 220VAC zero line to control the light on and off. Display. Note: The MCU may malfunction when the motor is turned to low speed, that is, the rotating blade only enters once, and there may be two switching problems. loop detector can the test confirms normal.

2. loop detector Product high and low-temperature work test: Test conditions: put the product in a constant temperature and humidity high and low-temperature box, test tools: high and low-temperature box multimeter, oscilloscope, etc.
Use the I-shaped inductor as the grounding coil (the sensitivity is within the standard), and put the product in the high and low-temperature box.
One stage: change between 0-70 degrees, the time is switched once in 1 hour, there is no crash in the test for 24 hours, and the A and B relay outputs are connected to see if there is any malfunction.
The second stage: change between -40 - +70 degrees, the time is switched once in 1 hour, there is no crash in the test for 24 hours, then change to 2 hours to switch the test to see if there is any crash, and connect the A and B relay outputs to see if there is any error. action. 3. loop detector Frequency and coil inductance input test method:
Coil inductance: 20UH-2000UH (our company will measure 25UH, 85UH, 108UH, 358UH, 500UH, 1000UH, 1200UH, 1500UH, 2000UH, other sensitivities are measured by the frequency meter) because different coils will have different frequencies. So The input frequency range is stable within 16KHz-130KHz. When testing this function, the 16-bit rotary dial code will be adjusted accordingly to see if it will be unrecognizable when the same coil has different sensitivity. Attention: When the ground detector is powered Instantly check whether there is a delay function of the MCU detection signal, mainly by checking the green indicator light, that is, the ground signal indicator light is bright or blinking. Under normal circumstances, the MCU immediately recognizes the ground sense coil.
