Panel Mounted Speed Indicator

Protocontrol manufacturer non contact type speed indicators and tachometers for indication of machine speed in panel control room. Inductive proximity switch is used as a sensor and is placed in close proximity of the rotating object. On this object, metallic plates are fixed. Sensor detects presence of metal objects which come within the range of their oscillating field giving rise to corresponding pulses. These pulses are fed to the control unit where they are compared with the standard pulses to sense the speed. The speed is indicated in rpm or linear speed units like meters per minutes
this indicator gives digital display as well as operates relay contact at presser speed.
special feature like scaling factor adjustment, relay contacts, analogue op, isolated non isolated output, multiple switching points, large size display for viewing from distance are also available.
Special enclosures like whether proof - flameproof enclosures are available.
