KD Scientific OS-250 Spill Sensor

The OS-250 System is designed to detect spills around sensitive equipment and to take preventative action if able. The system includes special moisture-sensitive mats consisting of material specifically developed for detecting liquid spills. A simple electrical connection between the moisture-sensitive mat and KD Scientific’s OS-250 Controller sets the alarm. When as little as three drops of water touches the mat an audible alarm is triggered and an LED starts flashing.

In addition to sounding an alarm, the OS-250 Controller can turn the power off to any device that is plugged into its single, switched power outlet. The power outlet of the OS-250 controller can supply up to 10 A of current and will easily control syringe pumps or valve controllers.

Components

The OS-250 System is comprised of moisture sensitive mats (4), the OS-250 controller, a sensor cable with mat-clip, and a line cord for connecting the switched power output of the OS-250 controller to a powered device such as a perfusion system. These components are shown below.

• Mats

  The moisture sensitive mats represent the heart of this system. Mats are made from a multi-layer, non-woven, carbon impregnated material and can be cut to any size or shape. They are resistant to most organic solvents. They can also be reused following exposure to salt solutions.

• OS-250 Controller

  The OS-250 controller provides the system’s functionality. The front panel houses the input BNC for the sensor cable, an alarm LED, an internal alarm speaker and the power switch. The instrument rear panel houses an outlet for the switched power cable, a connection port for the instrument line cord and a fuse assembly.

• Sensor cable

  The sensor cable connects the moisture sensitive mat to the controller. The mat-clip can be attached anywhere on the mat to provide full functionality.
