DÉTECTEUR DE ROTATION ROTO SPEED

Caractéristiques Principales

  • Universal assembly suitable for any rotating shaft with a suitable connection
  • Standard assembly for close integration on Rotolok Rotary Valves and Blowing Seals
  • Monitors shaft speeds from 2.5 up to 200 RPM
  • Sensor can be reset to suit
  • Compatible with a range of electrical control systems

Le détecteur de rotation Rotospeed peut être utilisé sur tout type de matériels, là ou le contrôle de rotation de l’arbre est nécessaire.

Avec un design compact et un fonctionnement efficace, il est idéal pour le sas alvéolaire, le convoyeur à vis et l’élévateur  à godets, pour détecter la vitesse basse ou haute de rotation.

Le Rotospeed a été initialement développé pour les sas alvéolaires en remplacement  d’une surveillance visuelle.

Pour d’autres applications (par exemple, convoyeurs à bande, les élévateurs à godets, et les entrainements à vis) où toutes variations de vitesses hautes ou basses nécessitent une détection  plus précise et pointue, le détecteur de rotation Rotospeed a été conçu pour répondre à ces besoins.

The heart of the switch is its sensing head with its built in switching device. The head detects the blades of a rotor mounted on the shaft to be monitored. The sensing head switch is activated when the rotor frequency matches or exceeds the switch’s setting frequency.

The switch will de-activate when the rotor frequency falls below the switch’s setting frequency.

The switch is suitable for operation over a range of 2.5 to 200 RPM but this range can be extended if details are given on application.

Care must be taken not to overload the switch and these details are as charted. In all cases it is recommended to install’ prior to the Rotospeed, a 5A protection fuse.

(Different sensing heads can be used for alternative applications,
(Details given on application))

The shaft being monitored should be tapped M12 in accordance with the planning in drawing and to overcome the problem of eccentricity or the hole not being coaxial, an anchor bracket should be fitted to stop rotation of the switch. By locating rather than bolting the Rotospeed firmly to the bracket, bearing overload is prevented.

All dimensions are in mm unless otherwise stated

The total unit is housed in a weatherproof cast aluminium housing and can be directly coupled to the monitored shaft and is suitable for running in clockwise or anticlockwise direction.

The proximity switch provides an open circuit when de-energised and operates from a 12-240V DC or 24-240V AC 50/60 Hz supply. Mounting positions can be horizontal, vertical or at any convenient angle.
