The SS1 monitor is a plug-in module which functions by detecting the speed of a moving bolt head, toothed wheel or other suitable competent. Reciprocating, rotating or vibrating mechanisms may be successfully monitored by this technique. Linear motion detection is also possible where evenly spaced components can be sensed.

When the speed falls below a pre-set minimum, an internal relay operates after an adjustable time delay. The relay contacts may be used to provide interlock facilities within the machine control systems. The actual sensing component used is normally an inductive proximity switch. However, provision is made within the SS1 to enable magnetic sensors to be employed.

In shaft stop applications, the monitor can prevent machine guards from being removed from still-rotating parts. The system required only a single pulse to ensure complete protection for the whole of the elapsed time period.

Applications include: Shaft stopped detection, Machine guard interlocks, Flow line supervision, Conveyor motion sensing, Vibration monitoring, Frequency switch.

Features of the SS1 Include:

• Fail safe operation
• Completely sealed sensors
• Very low speed operation
• Multiple sensor amplifier
