GENERAL DESCRIPTION
The Model P AXLSG expands the PAX Lite capabilities into the indication of
pressure, load, force, and other parameters measured with strain gages. The unit
features broad range scaling and can be used with a wide variety of strain gage
resistances and bridge configurations. A built-in excitation source is jumper
selectable for 5 or 10 VDC @ 120 mA maximum, and can power up to four full
350 bridges in load averaging applications. Although designed primarily for
strain-gage indication, the P AXLSG is also ideal for single-ended or dif ferential
millivolt input applications, with full-scale input ranges from 0 to 10 mV thru 0
to 2 VDC. Adjustable scaling and offset allow direct readout in nearly any
engineering unit.
The meter has a NEMA 4X/IP65 sealed bezel and extensive testing of noise
effects to CE requirements, allowing the meter to provide a tough yet reliable
application solution.
DIMENSIONS In inches (mm)
Note: Recommended minimum clearance (behind the panel) for mounting clip installation is
2.1" (53.4) H x 5.0" (127) W.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
CAUTION: Risk of electric shock.
