RPRR

For transformer and other electrical apparatus protection. Device sends an alarm when a dangerous sudden pressure rise condition has occurred. This alarm can be used to trip the transformer offline preventing further damage or purely as an indicator of an event.

Standard
  • Models designed for use in oil or gas space
  • 100% tested for pressure rate release point
  • Protection and detection of dangerous sudden pressure changes
  • Devices calibrated to quickly alarm or trip during rapid pressure rise changes
  • Actuation only occurs based on rate of pressure rise and will not occur under normal pressure variations caused by temperature change and vibration
  • Can be subjected to full vacuum or 20 psi positive pressure without damage
  • Standard operation from -40 to 180°F ( -40 to 82°C)
  • Special units available for operation at -67°F (-55°C)
  • 100% factory calibrated and tested to ensure performance
  • Units are serialized and calibration records maintained
  • Factory tested for switch (contact) performance and response
  • Field test kit available for simple GO/NO-GO test to assure proper functionality of the device
  • Multiple mounting and calibration options for gas or oil applications
  • Flange or thread mounting options available for vertical or horizontal mounting
  • Models calibrated for proper response in gas or oil space applications
  • From the original creator of mechanical rapid pressure rise relays
  • Original creator of patented bellows technology for mechanical rapid pressure rise detection
  • Over 25 years of experience and refinement in rapid pressure rise protection with greater than 100000 units installed

Option
  • Horizontal or vertical mounting
  • Seal in relay (QUALITROL 909) for latching alarm or trip signal
  • Electrical connection types, cable size, lengths and wire colors
  • Gas bleed system
  • Field test kit (KIT-013) and factory test fixture (FIX-601)
  • Flange or thread mounting
  • Stainless Steel
