Product Description

Zero Speed Switch

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. 

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.


Sensor Probe : Totally enclosed, IP 67, Inductive Type, suitable for use in harsh, dusty and oily environment. Do not effected by immersion under dust and water.
  • Enclosure : Tubular, Ni-Cr plated Brass enclosure, M 30 size with two check nuts (Refer group 4 of ordering proforma for (other options)
  • Sensing distance : 10 - 12 mm nominal, 8-10 mm operational. 
Control Unit :
  • Enclosure : Field mounting IP 65, Cast Al / Din Rail IP 30 /Corrosion proof DMC-SMC (FRP) / Cast Al Flameproof.
  • Output : 2 NO + 2 NC relay contact, Rating 5 Amp resistive at 230 V AC) With LED indication for Supply ON, Sensor ON and Relay ON. Initial Time Delay : Initial time delay facility to allow the rotating mechanism to achieve the desired speed is provided. Standard delay is 0-30 sec.
