DESCRIPTION

Measurement
Specialties,Inc.
offerscomprehensive measurement solutions including
electronic signal conditioning and display units.
In conjunction with its sensors, Measurement
Specialties, Inc. offers a wide range of conditioning
electronics. The XAM-IC In-line amplifier provides theuser with a compact module translating the output fromany Wheatstone bridge transducer into a 4 to 20 mA
output on 2 wires.

Features

Current Output 4...20 mA (current loop)
Power Supply 10 to 36 V
Suited for Wheatstone Bridge Sensors
Zero and Gain adjustments by trimmers
Connector and / or Sealed Cable OutputApplications
Suited for Wheatstone Bridge Sensors
For on board sensor installation
Laboratory and Research

TE SENSOR SOLUTIONS /// XAM IN-LINE AMPLIFIERThe zero for a 4 mA output can be adjusted bya potentiometer, externally accessible. The gain is
usually factory set, but a gain set potentiometer allows
individual fine tuning.
The XAM-IC requires 10 Vdc to 36 Vdc power
supply and is protected against reverse polarity.
For easy installation, the standard version issupplied with a miniature connector on the sensor’s side,
but it can also be delivered with cable glands and 1 m
cable on each side, or with a second connector.
With its rugged and compact metallic housing,the XAM-IC is suited for on-board applications.
