The ARC 4100—highly dependable analog recording for up to two process variables.
Utterly
Dependable
and easy
to operate.
he ARC 4100 is a circular chart recorder capable of
T
measuring, recording, and controlling up to two process variables. Its analog design provides protection from
electronic noise interference, making it a highly dependable device. Applications for this instrument are many
and include temperature, relative humidity, pH, level,
electrical measurement, and flow. The ARC 4100 operates with either 115V AC or 230V AC line voltage at 50 or
60Hz; voltage and frequency are selected when ordering.
It accepts a variety of inputs and can be ordered with
RTD, thermocouple, and analog inputs. The process
input for each pen is configured at the factory according
to the range ordered and directly connects to either
thermocouple, RTD, mVDC, VDC, or mADC inputs.
Changes to input type are easily accomplished in the
field simply by changing the range module. Outputs
include On/Off, time proportioning, and 4 to 20mA
with full PID. All recording, controlling, and alarm capabilities/options are selected from the order matrix for
factory implementation.
This recorder incorporates a 10” circular chart. These
charts are available in a wide selection of zero-based,
non-zero based, reverse, and dual-scale ranges. The pens,
disposable fiber-tip types, are quickly and easily replaced.
The ARC 4100 is backed by a one-year warranty as well
as free technical support throughout the life of
the product.
