Series NSS Non-Contact Speed Switch, set point range 100-5,000 RPM, 115 VAC, no disc
Compact Housing, Easy Installation
The Series NSS are self-contained rotation monitoring systems that are ideal for detecting the unwanted slowdown of process equipment. These systems bring efficiency and safety to your operations by preventing machine damage, product waste and costly downtime. The non-contact speed switch is commonly used to monitor drive trains, power-driven components, crushers, exhaust fans, screw conveyors, or tail pulleys on belt conveyors and elevators. The standard system includes either an NSSP-series switch and a pulsar DISC.
Miniature speed switches contain a sensor and switching electronics in either a chemical/corrosion resistant PVC housing (NSSP series). Each switch is used with a shaft-end mounted pulsar DISC which generates an alternating magnetic field that is picked up by the speed switch. The switch decodes this frequency signal to determine shaft speed and compares this to the pre-adjusted set point, easily calibrated via a single-turn potentiometer. In the event of rotational failure, such as a broken drive, belt slippage, product overloads or clogs, the relay can be used to provide an alarm or equipment shutdown, assuring machine protection and process integrity. The miniature speed switch series is fail-safe; any malfunction during operation will de-energize the control circuit.
