Groups A, B,C, and D; Class II, Division 1,
Groups E,F, and G and Class III, Division 1

The Model IS-2 amplifier provides intrinsically safe circuitry
for MAGPOWR load cells. It is specifically designed for safe,
accurate measuring and controlling web tension in
hazardous locations. When used with the IS-2, all MAGPOWR
load cells are UL approved for Class I, Groups A, B, C and D;
Class II, Groups E, F, G and Class III. This allows the load
cells to be mounted directly in the hazardous area without
air purging.
The IS-2 amplifier is compatible with all MAGPOWR load
cells, tension readouts and tension controls. An auxiliary 0
to 10 VDC analog signal proportional to tension is available
for interfacing to other controls. A calibration range of 8:1
allows you to use the load cells at 1/8th of their capacity
and maintain full scale meter indication of total web
tension. When used with MAGPOWR load cell cables, the
IS-2 amplifier must not be mounted more than 30.5 meters
(100 feet) from the load cells.
