Electronic Speed Monitor

We are offering microprocessor based speed monitor.
Now a day in material handling plants under over speed monitor is one of the essential control and safety device.
application:
electronic speed monitor is used to monitor speed of conveyors, crushers, rolling mills, agitators, mixers, stirrers, screw conveyors, and other industrial machinery. This device actuates relay contacts at preset speed. Using these contacts desired control action such as zero speed protection under speed protection over speed protection can be achieved.
operation:
the basic principle of speed monitor is comparison of pulses received from sensor with standard pulses. The unit consists of two parts: "sensor probe" and control unit. The sensor is to be installed with its sensing face in close proximity of rotating object. On this object, flags are to be fixed. The sensor produces strong electromagnetic waves, which get disturbed by the flags, giving rise to corresponding pulses. These pulses are fed to the control unit where they are compared with standard pulses to sense the speed.
micro controller based, speed indicator monitor - tachometer
features:
micro controller based circuitry packed with customer friendly features. Same speed monitor is used for indication of rpm or mpm (linear speed)
selectable number of flags: enter number of flags which are available at site, speed monitor will get automatically calibrated for these flags
relay contact op for tripping
digital display
adjustable trip delay
settable hysteresis
special models for combined under over speed monitoring duty
