Torq speed responsive switches are used in bulk material handling systems to monitor speeds of conveyors and other types of rotating machinery. Torq switches are designed to activate an alarm system and/or initiate a control action to prevent downtime of machinery. Speed switches provide protection from speed related damage including broken belts, overloads or belt slippage.

APPLICATIONS:
Steel mills
Mining
Ore handling
Foundries
Food processing
Chemical processing
Power plants

BENEFITS:
Rugged, Self contained construction allows used in hazardous or non-hazardous locations
Detect overspeed, underspeed, or zero speed in conveying systems with settings chosen by user
Digital solid state integrated circuitry provides long service life
Detection of speed covers complete standard range of 1-5000 RPM with premium accuracy
Special option available - ranges from .1 to 500 RPM)
Ease and flexibility of installation

GENERAL SPECIFICATIONS:
Input power: 115 or 230 VAC, 50/60 hertz (12 or 24 VDC available on some units)
Operating temperature range: -220F to 1500F (-300C to 660C)
Direction of rotation: Either

SWITCHES WITH NEMA 4 ENCLOSURE
