Speed Monitors

Fit & Forget Technology!
A range of stopped motion, over or under speed monitors, designed and manufactured in the UK by SYNATEL. Available in self contained or modular (plug in base) form with separate proximity sensors. ATEX and IECEx approved sensors are available, which can also be used in non-approved applications.
Accessory items are also available, to allow easy fitting of sensors to shafts etc., without the need for additional guarding. (See Whirligig).
SYNATEL manufacture the UK’s largest range of industrial electronic sensing, counting and control equipment for industry, including ATEX and IECEx sensors, ATEX and IECEx components and switches, ATEX and IECEx enclosures.
(If you have a special requirement, use our contact us page with details).

ROTASTOP SU1MZAI Stopped Motion Monitor EN 60079/IEC 60079 (Dust zone21/Gas zone1)

ROTASTOP SU1MZAI Stopped Motion Monitor
ATEX EN 60079/IECEx 60079
(Dust zone21/Gas zone1)

Rotastop SU1MZAI. An 18mm diameter, fully self contained unit, incorporating a proximity sensor & associated stopped motion circuitry. The output maintains it’s ‘on’ state whilst the target is moving. Manufactured by SYNATEL it is ideal for chain or gear driven shafts. ATEX EN60079 & IECeX IEC 60079 hazard area use approved.

Underspeed Monitor EN 60079/IEC 60079 (Dust zone20/Gas zone0)
