- Page 7 MODEL 482A21 LINE POWERED SIGNAL CONDITIONER 1.2 Introduction ® Model 482A21 is a single-channel, line-operated signal conditioner for ICP transducer systems. This unit provides constant current excitation to the built-in transducer amplifier and decouples the signal from the DC bias voltage. The unit also contains provision for fault monitoring the channel, as well as provision for externally varying the constant current output over a 2 to 20 mA range.
- Page 8 MODEL 482A21 LINE POWERED SIGNAL CONDITIONER ® When an ICP transducer (or in-line amplifier) is connected to the INPUT jack, the front monitor meter indicates approximately midscale (green) if the transducer or amplifier is functioning properly. It does not read midscale if the transducer bias is 3 to 5 volts.
