Carrier-frequency pulse amplifiers 19 Versions • Round stainless steel housing for all measuring cells • Aluminium die-cast housing for gear flow meters • Cartridge housing for micro meters and gear flow meters • Double pickup for forward / backward detection and pulse multiplication Carrier frequency pickups detect contactless the rpm of the KEM flow meters. Each time a gear tooth passes by, a free running oscillator is damped. The frequency of the resulting amplitude modulation of the carrier is equal to the wheel `s rpm and therefore corresponds to the value of the flow. The output signal of the pickup is amplified, converted and transmitted in the form of current or voltage rectangular pulses. Carrier frequency pickups are characterized by a wide frequency range, low power consumption and high noise immunity. For applications in hazardous areas, we offer intrinsically safe sensors and amplifiers with Ex protection in accordance with ATEX, RTN, CSA and other testing standards.
