Description
A two- or four-channel rupture disc monitoring console that notifies your control room of ruptured discs.
When disc rupture occurs, the MTB-700's intrinsically safe, galvanically isolated barriers activate output signals or relays to alert operators and trigger pumps, valves, or other equipment connected to the system.
A critical component of a complete burst disc indicator (BDI) alarm system, the MTB-700 alarm monitor connects to up to four rupture discs to alert the nearby control room of ruptured discs.
When a disc ruptures, the MTB-700's intrinsically safe, galvanically isolated barriers activate output signals or relays to warn operators and trigger pumps, valves, or other equipment connected to the system.
Rupture Discs, the BDI Alarm System, and the MTB-700 Alarm Monitor
The BDI alarm system is based on an electrical circuit. Normally, a continuous signal flows between the BDI alarm strip and the MTB-700 alarm monitor. When the disc ruptures, the alarm strip is severed, opening the circuit and interrupting current through the strip.
The MTB-700 alarm monitor contains several replaceable modules and channel relays. Each channel relay connects to one alarm strip. When a rupture disc breaks its BDI alarm strip, a relay is activated, sending a signal to the control panel.
Control panels, annunciators, light panels, or other signaling devices can be used to warn of a ruptured disc.
Individual relay circuitry allows the MTB-700 to monitor several rupture discs at once. Pumps, valves, and other systems can also be activated to respond to an overpressure or vacuum situation when an alarm strip breaks.
Technical Details and Options
An MTL5018AC barrier is used in the MTB-700 alarm monitor with a 120/240 VAC input power option. An MTL5018 barrier is used in the MTB-700 alarm monitor with the 24 VDC input power option.
