FOR RELIABLE AND ACCURATE TRAFFIC PLANNING AND DATA COLLECTION
IRD DYNAX® Axle Sensor
- Resistive sensor specially designed to operate independent of speed in stop-and-go traffic
- Rugged and reliable
- Can be permanently installed with epoxy in a sawcut in asphalt or concrete surfaces or held in place by locking bars in a treadle frame
- Sensor replacement significantly reduces traffic control and road closure expenses
IRD DYNAX® Treadles
- Are ideal for toll plazas
- Available in a variety of models, including single, two, three and four sensor models
- Can be retrofit into existing frames or supplied with frames for new installations
- Sensors are individually replaceable, minimizing downtime and treadle replacement expenditures
Burst
- Speed independent
- Both in-road & treadle models
- Individually replaceable
PIEZOELECTRIC SENSORS
MSI (Measurement Specialties Inc.)
- The MSI BL sensors’ unique flat design results in a more accurate count by rejecting road noise and reducing “ghost axles”
- Constructed with proven components and assembled in a unique way to improve longevity and uniformity
- Encapsulated sensor available for good adhesion to the epoxy and protection of the sensor
Available in a variety of sensor lengths
Thermocoax Inc.
- Specially designed for shallow installations in thin or reinforced pavements where deeper excavation is a problem
- Steady output signal over the complete axle
- Proven sensor technology independently tested by FHWA
Burst
- Class 1 for Weigh-In-Motion; Class 2 for Vehicle Classification
- Portable & Permanent
Non-Intrusive Vehicle Detector
- Counting, lane occupancy, average speed and classification for highways, rural, and grid roads including gravel roads and bridges
- No traffic sensors installed in the road or on the top of the road surface
- Minimal installation time
- In most instances, no road closure required
- Low power consumption
- Wireless option available
Applications include:
- Permanent and mobile counting stations

Inductive Loops & Magnetometers
Inductive Loops
- Permanent loops of any dimension for installation with epoxy in roads
- Temporary loops which are secured onto the road surface with adhesive tape
- Preformed loops for new roads
Magnetometers
- Direct replacement for inductive loops
- Quick installation with a single 3/8” sawcut
- Compact, robust one-piece construction
- Designed to reduce the effects of temperature fluctuations and destabilizing magnetic fields
- Vehicle presence, counting, speed and classification
- Other applications include care wash entry/exit, drive up kiosks, overhead door activation, loading docks and gate control.
Burst
