double Loop Detector for car detecting
Double Loop Detector:
This is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.
Technical data:
1. Supply voltage AC: 220V, 110V, 24V, 12V
2. Supply voltage DC: 24V, 12V
3. Sensitivity: Adjustable in 3 increments (high .medium. low)
4. Operating temperature: -40°C to +65°C
5. Storage temperature: -40°C to +85°C
6. Frequency range: 20 kHz to 170 kHz
7. Reaction time: 100ms
8. Loop inductance: Ideal:80μH to 300μH (incl. conn. wiring): max: 50μH to500μH
9. Loop connection: <5m optimal
10. Loop connection wiring: Maximum length 200 meters,twisted at least 20 times per meter
11. Dimensions: 35x74x85 mm (W x H x L)
12. Net Weight: 300g
13.Frequency:the frequency can be altered by means of DIP6-Switch.
u to eliminate interference of two neighboring wire loops
u to eliminate interference of two neighboring loop detectors
u to eliminate interference of two neighboring distribution cables (loop detectors)
Attention:
When using more than 2 Detectors, please select different frequencies ,and screened cables for Detector or connecting cables widely separated
Sensitivity:
In order to calibrate on site the wire loop to the loop detector, the sensitivity can be adjusted on the front of the housing by means of a three-stage sliding switch.
Ø High: high sensitivity (e.g. also bicycles can be detected)
Ø Medium: medium sensitivity (e.g. for automobiles)
Ø Low: low sensitivity (preferably Lorries will be detected)
Ensure that the loop is NOT activated when making these adjustments.
