Zero Speed Switch, Electronic Speed Switch

Listing ID #511218

We are offering zero speed switch, electronic speed switch.
Protocontrol make zero speed switch series: esm is designed for indication & monitoring of rotational speed of the drive used on machines like crushers, conveyors, centrifuges, mixers & agitators.
The speed monitor which uses non-contact sensor like inductive, capacitive, magnetic or optical proximity switch to sense the speed & actuates a relay at preset speed. Using contacts of this relay desired control action such as zero speed protectionunder speed protection over speed protection under & over speed protection can be achieved. The model with digital display facility normally indicates actual speed of the equipment. Speed monitor displays set speed when push button is pressed. Hence accurate speed setting is possible.
the op is in the form of 2co relay contacts. Bcd op is also available in special versions. Speed range from 1 to 6000 rpm using inductive proximity switch as a sensor & 500-5000 rpm using magnetic or optical sensor can be covered in six ranges.
the enclosure for monitoring unit is panel-mounting type ip 30. A special sturdy cast al enclosure suitable to ip 65 grade can be provided when the when the unit is required to be field mounted. Supply voltage to the control unit is 240 v ac, or as per requirement. Special features such as digital display, direction sensing, multi range model, differential or slip speed monitoring, analogue op are also available. Versions substitute to imported one are also available.
