ELECTRONIC SPEED SWITCH
These are non-contact type speed monitoring units for monitoring Over-speed / Under-speed of any rotary or linear motion. The units are available as 2 part version (Monitoring unit + Sensor probe). The units are available for indoor & outdoor applications in different enclosure. The standard models are having a potentiometer for setting & a relay operates at preset value. Special purpose models are available with Digital indication / 4-20 mA output / RS-485 port. Wide range of speed sensors (Inductive / Magnetic / Optical). Speed sensing range from 0.1 to 10,000 RPM. More than 40 models. The standard models are : RM 221, RM E21, RM P261. Special models for sensing wind-speed (Anemometer), Belt speed and Belt loading. Useful for safety of Bulk Material Handling Conveyors in Coal, Cement, Fertilizer, Sugar, Process Industries.
