XField

Terrain-Following Volumetric Sensor

XField is a terrain-following volumetric sensor that generates an invisible field of energy around parallel sets of wires. When an intruder enters the field, an alarm is generated. XField is designed for high-security environments and can be used in free-standing, fence-mounted, roof and wall applications. In particular, XField has been a popular choice for nuclear power facilities due to its adjustable height capabilities.

Features

Detection Capabilities

  • Detection height for free-standing and wall applications: 6.1 m (20 ft)
  • Detection height for fence installations: 7.3 m (24 ft)
  • Zone length: ~ 150 m (500 ft)

Flexible Deployment Options

  • Supports free-standing, fence-mounted, roof and wall applications.
  • Tall, narrow, well-contained detection zone allows the sensor to be installed in a wide variety of applications and minimizes nuisance alarms caused by nearby moving objects.
  • Meets U.S. Nuclear Regulatory Commission (NRC) Regulatory Guide 5.44 requirements

Easy Installation and Maintenance

  • Durable design simplifies installation and maintenance
  • Local or remote configuration and diagnostics
  • Corrosion-resistant hardware

How It Works

Digital Signal Processing (DSP) analyzes the capacitance of XField’s sense wires and uses the amplitude of change (size of the intruder), rate of change (movement of the intruder) and the time the target spends within the detection fields to qualify the alarm. Each XField processor provides two zones of detection, A and B. Each zone can be configured with either 4 wires (two field wire and two sense wires) or 5 wires (three field wires and two sensor wires). To increase the height of the detection area, the A and B zones can be stacked.
