Description
The APD 4058 accepts an input from a strain gauge, bridge
type sensor, load cell, or pressure transducer.
It filters, amplifies, and converts the resulting millivolt signal
into the selected DC voltage or current output that is linearly
related to the input. The output is not electrically isolated.
The adjustable excitation power supply generates a stable
source of voltage to drive your sensor.
Input, output, excitation and zero offset are field configurable,
via external rotary and slide switches.
Offsets up to ±100% of span can be used to cancel sensor
offsets or non-zero deadweights (taring).
Sink/Source Versatility
For maximum versatility the APD 4058 milliamp output can be
selectively wired for sinking or sourcing. This allows connec-
tion to any type of mA input receiving device.
LoopTracker
API exclusive features include two LoopTracker LEDs (green for
input, red for output) that vary in intensity with changes in the
process input and output signals. These provide a quick visual
picture of your process loop at all times and can greatly aid in
saving time during initial startup and/or troubleshooting.
Output Test
An API exclusive feature includes the test button to provide a
fixed output (independent of the input) when held depressed.
The output test button greatly aids in saving time during initial
startup and/or troubleshooting. The test output level is potenti-
ometer adjustable from 0 to 100% of output span.
The output test is not available with the M01 or M02 options. A
calibration resistor switch replaces the test button.

Strain Gauge Input Ranges
Minimum range:
0 to 5 mV
Maximum range:
0 to 1200 mV
Minimum sensitivity: 0.5 mV/V
Maximum sensitivity: 120 mV/V
Millivolt output range is determined by the sensitivity of the
sensor (mV/V) and the excitation voltage applied.
