Overview
High-performance 4-core shielded cable designed specifically for vibrating wire sensors.
Our specialized Vibrating Wire Sensor Cable is engineered to preserve the integrity of frequency signals over long distances. It features twisted pairs to reject magnetic interference and a foil shield to block electrostatic noise. The rugged polyurethane (PUR) jacket provides exceptional resistance to cuts, abrasion, and UV radiation, making it suitable for surface laying or direct burial in concrete.

Detailed Description
Signal Integrity
Vibrating wire sensors rely on a clean frequency signal. Standard electrical cables often act as antennas, picking up 50/60Hz noise from nearby power lines.
Our cable uses tight-twist pairs to cancel out electromagnetic interference (EMI), ensuring that the reading at the logger is exactly what the sensor transmitted.
Mechanical Strength
Construction sites are brutal. Cables are often run over by trucks or dragged across rebar.
- Cut Resistance: The PUR jacket is 3x tougher than standard PVC.
- Tensile Strength: Reinforced with Kevlar strands (optional) to prevent stretching during vertical installation in deep boreholes.
Moisture Resistance
Water ingress is the #1 killer of geotechnical sensors. This cable features a water-blocking swellable tape/yarn design.
If the outer jacket is nicked by a rock during backfilling, the internal layer swells upon contact with moisture, sealing the damage and preventing water from traveling down the cable to the sensor electronics.
Temperature Stability
Designed for extremes, this cable remains flexible at -40°C, making installation in winter conditions manageable without the jacket cracking.
