Product Description
Single Channel Detectors
The innovative TD136 series of single channel inductive loop vehicle detectors are used to detect vehicles presence by means of an inductive loop buried under the road and have all the features and benefits found on much larger modules. No longer is it necessary to make compromises when selecting a detector for Traffic control, counting or traffic analysis - these "one-chip" microprocessor-based units are suitable for them all. Available in standard & custom variations these detectors can cater to your every system requirement.
Applications
- Traffic Control Applications
- Vehicle Counting
- Toll Systems
- Traffic Analysis
Features
- Compact Size: This compact and well engineered housing combines all of the industry requirements regarding features and functionality and allows this detector to be incorporated into any new or existing traffic detection system.
- Diagnostic Capabilities: Comprehensive diagnostics capabilities allow for accurate diagnosis of loop and installation problems.
- Selectable Presence: The output of the presence relay can be selected to maintain an output for an extension period, or defined presence output times.
- Loop Isolation Protection: The loop is isolated and provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops. Added filtering reduces interference from external noise.
- Loop Frequency Indication: Interference between adjacent loop / detectors can be determined by an integral indication, and eliminated by changing the frequency settings.
- Environmental Analyser: Continuous monitoring of external parameters ensure reliable product performance & operations under all environmental and power supply conditions.
- Delay on Detect: Provides a turn-on delay, thus allowing selective detection which is often useful for screening out unwanted inputs.
- Visual Fault Monitor: A fault indication is provided in the event of the loop input becoming faulty, or alternatively if the loop is out of the operational range. This feature will help in localising the fault in the event of a maintenance call-out.
