The DP63300-TC thermocouple
meter accepts inputs from standard
thermocouples and precisely
linearizes them. A full 4-digit display
accommodates a wide range of
temperature inputs. The unit
automatically compensates for cold
junction, NBS linearity and the
meter’s zero and span.
The meter features a readout choice
of either Fahrenheit or Celsius with
0.1 or 1° resolution. Display prompts
and front panel buttons aid the
operator through set-up and
operation. With a few simple steps
the unit can be used as a millivolt
meter. This mode is useful in
monitoring and displaying the actual
voltage produced at the
thermocouple probe junction and as
an aid in troubleshooting for a faulty
thermocouple probe.
The meter provides a peak “HI” and
valley “LO” reading memory with
selectable capture delay time. The
capture delay is used to prevent
detection of false peak or valley
readings that may occur during
start-up or unusual process events.
The peak and valley readings are
stored at power-down so that
process limits can be monitored
over any length of time.
Programmable digital filtering
enhances the stability of the
reading.
All setup data is stored in E2PROM,
which will hold data for a minimum
of 10 years without power. The
meter has several built-in diagnostic
functions to alert operators of any
malfunction. Extensive testing of
noise interference mechanisms and
full burn-in makes the indicator
extremely reliable in industrial
environments. The front bezel meets
NEMA 4X (IP65) requirements for
wash-down applications.
