Speed Indicators, For Automobile Use, Industrial Use, Feature : Clean View, High Strength

Protocontrol offers micro controller based non contact speed indicator to continuously display speed of rotating machinery. Digital speed indicator is housed in robust cast al field mounting enclosure or sheet steel front panel mounting enclosure. The speed indicator is used to indicate and monitor speed of rotating machinery like conveyors, crushers, rolling mills, stirrers, screw conveyors, and other industrial machinery. As the speed is also displayed simultaneously, the setting and control action is easy. Linear speed can also be displayed. this unit consists of two parts, control unit & sensor probe. The basic principle of speed monitor is comparison of pulses received from sensor with standard pulses. The sensor is to be mounted with its sensing face in close proximity of the rotating object. Flags are to be mounted on the rotation object, which are to be sensed by the sensor. this device actuates relay contact at preset speed. Using these contacts desired control action such as zero speed protection under speed protection over speed protection can be achieved. initial time delay facility of 0 to 30 seconds is provided to allow the rotating mechanism to achieve the desired speed. Speed setting is possible from 1 rpm to 5000 rpm in optional ranges. Direction sensing and speed monitoring of various locations from single point is possible. The sensor is epoxy potted & housed in metallicplastic tube. Control unit is enclosed cast al dmc enclosure
