Intrinsically safe radio-frequency rotational speed sensor
SPECTEC's Intrinsically Safe RF pickups are FM Global approved per Approval Standard 3610 for Intrinsically Safe (Class I, Div I and Class I, Zone 0 - code AEx [ia]).
Many SPECTEC speed sensors are CE compliant to EN55011 and 50022-2 standards.
Intrinsically safe RF pickups or modulated carrier sensors are applicable for reading gear teeth or turbine fan blades with low speed and low drag requirements in hazardous environments. These non-powered or passive RF pickups are rated Intrinsically Safe for use in areas that call for sensors that limit the energy of any possible sparks and limit the surface temperature. Intrinsically safe RF pickups are also available in male and female conduit-mount body styles.
