What does the Rota-tally do?
The Rota-tally is a non-contact, field retrofittable, rotary shaft sensor designed to easily measure shaft rotation and speed in harsh environments. This product is field retrofittable to a magnetic shaft mounting (1.5″) with chain mounting.
Designed for harsh environments, the Rota-tally can withstand hazardous conditions and provide measurements in temperatures from -25°C to 80°C. It can be used to measure shaft rotation and speed in various environments including:
- Industrial presses and rolling plants
- Conveyor machinery
- Paving plants
- Power generation
- Mobile construction equipment
