Aimed at applications where RF engineers need to consider the interference effects of nearby vibrating machinery, Radiometrix has developed the HVR2.
The HVR2 is a radio receiver module (a high vibration resistant version of the Radiometrix RLC2) which is available in Australia, New Zealand and South East Asia from RF Modules Australia .
The HVR2 utilises the company’s proprietary hybrid Direct Digital Synthesizer (DDS) local oscillator design to make it almost totally immune to mechanical vibrations at frequencies below 500Hz.
When used in conjunction with the matching TLC2H-433-5 transmitter module, the HVR2 can provide users with a reliable 5kbit/s wireless data link, suitable for troublesome industrial environments.
Operating in the 433.05-434.775MHz band, the HVR2 can receive signals via 32 operating channels set through the serial interface (25kHz narrow band spacing). With a receiver sensitivity of -118dBm (for 12dB SINAD), the HVR2 can easily maintain an operating range of above 500m. It runs off a supply voltage between 3.7 and 15V, and draws a current of only 30mA.
The receiver has an operating temperature range that spans from -20 to 70°C, allowing it to deal with tough external conditions.
It conforms to both EN 300 220-3 and EN 301 489-3 standards. Applications most likely to make use of the HVR2 include machine tool control, remote crane operation, industrial telemetry/telecommand and heavy vehicle control.
