The XAM is a miniature in-line amplifier that adapts to most Wheatstone bridge based sensors (fitted with semiconductor or metal gauges).
Power supply is unipolar on the XAM-MV, which accepts 10 to 30 V unregulated voltage with outputs up to 10.5 V. The bipolar version XAM-BV requires ±12 to ±18 V regulated and stabilized supply with a maximum signal output of ±10.5 V. The zero can be adjusted within 20% of the dynamic range by a potentiometer, externally accessible. The gain is usually factory set, but a gain set potentiometer allows individual fine adjustments.
When used with metal gauge fitted sensors (or semiconductor gauges in a half bridge configuration) a shunt calibration resistance can be built into the amplifier to be easily set by the end user. The standard version is supplied with a miniature connector on the sensor’s side of the amplifier to facilitate installation. With its rugged and compact housing the XAM is designed for on-board applications.
