Thunderbird International Corp's active RF speed transducer meets many engineering transducer specs due to its ability to sense 316 stainless steel and aluminum targets, as well as the usual ferrous or magnetic targets. The active RF speed transducer allows the detection of targets through a 0.1” thick wall of 300 series stainless steel - making it suitable for detecting a rotating target through a pressure vessel wall. The greatest advantage of using the RF speed transducer technology is its ability to detect through a substantial non-magnetic metal wall with no magnetic braking effect, turbine rotors spin freely within flow meters, allows for a wider frequency range to be covered as compared to other detection technologies.
Active RF Speed Transducer Operating Principles:
The active RF speed transducer is a RF speed transducer with an internal signal converter in one unit. RF speed transducers are well matched to low flow applications that call for no magnetic dampening or drag on the target. These active RF speed transducers produce a digital output proportional to the speed of the target. Due to its zero magnetic drag, the active RF speed transducer is useful on very sensitive meters, such as turbine flow meters, that would be detrimentally affected by a magnetic field. The internal pre-amp provides a constant logic-level output and a better signal-to-noise ratio.
