Continental disc Burst Disc Indicators
MTB-700 Alarm Monitor
MTB-700 Alarm Monitor
A two or four-channel rupture disc monitoring console that notifies your control room of burst discs.
- Upon disc rupture, the MTB-700’s intrinsically safe, galvanically isolated barriers activate signals or output relays to warn operators and actuate 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 links to as many as four rupture discs to alert your nearby control room of ruptured discs.
Upon disc rupture, the MTB-700’s intrinsically safe galvanically isolated barriers activate signals or output relays to warn operators and actuate 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 relies on an electrical circuit. Normally, a continuous signal flows between the BDI Alarm Strip and the MTB-700 Alarm Monitor. Upon disc rupture, the alarm strip is severed — opening the circuit and disrupting the 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 actuated, 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 may also be activated to respond to an overpressure or vacuum situation when an alarm strip breaks.
Technical details and options
An MTL5018AC barrier is utilized on the MTB-700 Alarm Monitor with a 120/240 VAC input power option. An MTL5018 barrier is utilized on the MTB-700 Alarm Monitor with the 24 VDC input power option.
