The D-TEKTM Vehicle Loop Detector allows for detection of metallic objects entering into the field formed around the detection loop. We have designed the D-TEK with the following objectives in mind:

1. Compact package to allow easy installation into small operator housings.
2. All controls are accessible from the outside for easy installation and operation.
3. Integral loop conditioner is provided, to enable detector operation with marginal loops.
4. Provide all features and controls necessary for a variety of applications.
5. Use metal housing for maximum durability and RF resistance.
6. Provide maximum surge protection on all inputs and outputs of the detector.

We took extra care to achieve and exceed these objectives. For example, the controls are divided into two groups. The group on the front of the detector is for basic operation and the group on the back of the detector is for advanced settings. This way the more advanced settings are not visible to the casual user.

The D-TEK is made from aircraft quality anodized aluminum and all switches have gold plated contacts that are sealed for protection. The circuit is protected by an advanced thermal resettable fuse, snubbing circuitry on the relay contacts, Metal Oxide Varistor on the power input and triple protection on the loop input.
The D-TEK features are extensive and include full loop diagnostic with frequency counter, 10 sensitivity settings, delay and extend features, fail safe and “fail secure” operation, automatic sensitivity boost, pulse or two presence relay operation and more.
