Safety devices on steam boilers

Steam boilers are monitored by a 'safety chain' of devices connected in series. This unit simulates boiler operation and the 15 specific faults that can trigger safety alarms and system shutdowns.

• simulation of steam boiler safety chain operation
• safety chain includes level switches, pressure switches, and controllers
• transparent boiler for observation; pressure simulated with compressed air
• 15 selectable faults for safety logic training
• front panel with process schematic and indicator lamps
