Manufacturers of Shaft Encoders,
Speed Relays and Vibration Sensors
Minimising downtime, optimising plant efficiency
The ‘Rotech’ range includes motion sensors, encoders, vibration sensors, and associated speed relays. The heavy-duty sensors are installed on the end of the shaft or on the belt that needs monitoring. Then they transmit an electrical signal proportional to the shaft/belt speed to a suitable control unit. The control unit options comprise a ‘Rotech’ speed relay, a programmable controller, a computer, a data logger device, or other proprietary control equipment. For this set the alarm level of the control unit to just below the average running speed of the shaft.
If the shaft/belt slows below the set level, the control unit activates and can connect to alarm the operator or shut down preceding items of the plant. ‘Rotech’ motion sensors/encoders find applications wherever materials are transported or processed by conveyors, elevators, screws, crushers, mixers, etc.
Examples of applications for our products include factories, quarries, mines, power utilities, and dock installations. Also, handling food, grain, pharmaceuticals, chemicals, sand, stone, cement, ore, coal, ash, among others.
A single conveyor may run for long periods without problems, but not forever. The day will arrive when it starts to slip or slow-down, unless action is taken to switch off the conveyor, crusher, or the plant that feeds it, then spillage can occur. In a large plant with many conveyors and drives, the potential for problems will be increased by every additional drive element.
