ST-15-WX Overfill Prevention and Liquid Detection Monitor

Brand: Scully Signal Company
The Scully ST-15-WX series multiple point liquid level detection control units are available in two through twelve channel models. The ST-15-WX is commonly used to provide overfill protection, high level warning, low level warning and/or pump and valve control functions. 

They are well suited for multiple fixed storage tank and transport tank applications where individual display and/or output control is required. The output control function may be reversed to alarm for a dry sensor condition rather than a wet sensor condition for low level warning. 

The ST-15-WX enclosure includes individual red indicator lamps that light when a sensor is wetted, a power indicator lamp, an alarm acknowledge push button and alarm test push button. Once a sensor alarm is acknowledged the alarm output circuit is reset, however, the indicator lamp remains lit until the sensor is dry again.
Features
  • Incorporates Dynamic Self-Checking™ circuitry which monitors the controller, wiring, connections and sensors for faults thirty times per second
  • Signals an audible alarm and/or controls pumps and valves for automatic shutdown
  • Monitors from 2 –12 total sensing points depending on model 
  • Provides liquid level detection for a wide variety of petroleum and chemical products
  • Uses output sensors approved as intrinsically safe for use in Class 1, Division 1, Group D hazardous environments 
  •  NEMA 4 style watertight housings
  • Works in conjunction with either Scully field-proven thermistor or Instant-On optic sensors
