For use with HFM-8 heat flux Sensors
The AMP-12 Signal Conditioning Amplifier is designed for use with the HFM-8 series. Heat Flux signals of the transducer are amplified by a low noise, wide-band differential amplifier whose gain may be set at one of five discrete values between 1 and 5000.
All signal connections are at the rear panel of the amplifier. A four-pin female Lemo connector is provided for the connection from the Heat Flux Microsensor. The amplified heat flux and temperature outputs (single ended) are on BNC male connectors.
Batteries are recharged using a NiCd charger. The amplifier has a power switch on the front panel. Gains for heat flux and temperature signals are selected by multiple position switches. Ten-turn potentiometers are provided for screwdriver adjustment of the heat flux amplifier offset and setting of the temperature reference point. A battery test switch, state of charge, and charging indicator allow checking of the battery state and monitoring of the recharge process.
