ST420-LT- Integral ½ in flexible liquid-tight conduit fitting
ST420-DI- Integral ½ NPT female conduit port

 

The patented ST420-LT and ST420-DI detect passing magnets of a shaft-mounted pulser disc or wrap and output a smooth, continuous 4-20 mA analog signal in direct proportion to shaft rotation speed.


Custom speed and pulser disc/wrap PPR ST420-LT and ST420-DI models are available upon request.
