Watts Tekmar Snow/Ice Sensor 090 In-Slab

Snow/Ice Sensor 090

The Snow/Ice Sensor 090 is an in-ground sensor compatible with tekmar snow melting controls, engineered to autonomously detect snow or ice accumulation on driveways or walkways. With a generous length of 65 feet (20 m) of wire, this sensor eliminates the need for in-field splicing, ensuring convenience during installation. Its versatility allows for use in various applications, ranging from residential driveways to commercial emergency access entries. The sensor enables tekmar snow melting controls to activate the snow/ice melt system only when necessary, while also providing essential slab temperature feedback to the control unit.

Key Features:

  • Automatic snow/ice detection capability enhances system efficiency
  • Provides slab temperature sensing to ensure optimal control
  • Includes 65 FT (20 m) of cable for flexible installation and extended reach
  • Designed for long-lasting performance in driveway and walkway installations
