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)

ROTASLIP PU1TZAI/PU1TRHAI Underspeed Monitor
ATEX EN 60079/IECEx 60079

The Rotaslip PU1TZAI/PU1TRHAI underspeed monitors from SYNATEL are designed to detect a stud or bolt on a shaft and indicates a fault condition (open circuit) if the input speed reduces by 20% or more below set running speed. Ideal for belt driven applications. ATEX EN 60079 & IECEx IEC 60079 dust & gas hazard area use approved.

ROTAMATIC PU1DR(A) Underspeed Monitor EN 50281 (Dust zone21) + Whirligig WG1

ROTAMATIC PU1DR Underspeed Monitor

Designed, manufactured & supplied by SYNATEL, the ROTAMATIC sensor is a moulded, DIN standard limit switch packaged underspeed monitor with relay output.
Output goes open circuit if input speed reduces by 20% of programmed speed setting.

Modular Stopped Motion Monitor

MODUSTOP LSM48 Modular Stopped Motion Monitor

A modular stopped motion monitor, designed by SYNATEL to work with a separate proximity sensor. Output goes open circuit after time period if incoming pulses stop.

RMR48T

MODUSLIP RMR48/T Modular Under/Overspeed Monitor

An Underspeed or Overspeed module in a 48mm DIN standard enclosure designed, manufactured & supplied by SYNATEL. Single pushbutton calibration for set running speed and start-up delay.
