Radio-frequency rotational speed sensor / intrinsically safe
SPECTEC presents intrinsically safe RF pickup flow meter sensors. These sensors are approved by FM Global as per Approval Standard 3610 for Intrinsically Safe (Class I, Div I and Class I, Zone 0 - code AEx [ia]). A lot of SPECTEC speed sensors comply with CE to EN55011 and 50022-2 standards.
The sensors are also known as modulated carrier sensors. They are used for reading gear teeth or turbine fan blades requiring low speed and low drag in dangerous atmospheres. The picks are non-powered or passive RF. They have intrinsically safe rating for use in areas that demand sensors which can restrict the energy of any potential sparks and also restrict the surface temperature. These RF pickups with intrinsically safe rating can also be obtained as male and female conduit fitting types.
