Principle of Operation:
The AMP-13 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.

Construction:
All signal connections are at the rear panel of the amplifier.  A four-pin female Lemo connector is provided for leads from the Heat Flux Microsensor to connect to the amplifier.  Male BNC connectors are provided for the amplified heat flux and temperature output signals from the amplifier.  Connections and cables from the amplifier's output  to the customer's data acquisition system are customer supplied.    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.
