Qualitrol 900/910 Rapid Pressure Rise Relay

Patented mechanical device for detection of sudden pressure events based on the rate of pressure rise and safe limits established by transformer manufacturers. When a dangerous pressure rise has been detected, the Qualitrol rapid pressure rise relay (RPRR) will change state. This can be used as an alarm or trip signal to minimize the potential of transformer tank damage.

Options:

  • 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

Qualitrol 930 Rapid Pressure Rise Relays

Multi-function, electronic pressure monitor with adjustable pressure sensitive sensors that provide rapid pressure rise detection combined with seal-in relay functionality and static pressure monitoring and control. Features continuous outputs for integration with SCADA systems and remote monitoring. Optional multi-sensor models provide logic based operation to eliminate nuisance trip alarm potential.

Options:

  • Heavy duty transducers for high humidity applications
  • Weather proof enclosure for mounting outside the control cabinet
  • Single sensor or multi-sensor logic
  • Qualitrol 900/910 retrofit mounting plate
  • SCADA outputs (0-1 or 4-20mA
