Model DI-516, Multi-channel
Temperature Indicators / Scanner
|
|
|
This
compact and highly reliable instrument can accept any one type
of RTD or thermocouple sensors. All the thermocouple inputs are
compensated for cold junction error. The scanned channel number
is indicated on a 2-digit display and the scanned temperature
is indicated on a 3 1/2 digit display. Open sensor indication
is a standard feature. The temperature indication resolution is
10C.

This instrument can be used either in auto-scan
or manual mode. In manual mode the measured temperature can
be viewed one channel after another by pressing the 'Advance'
switch. In 'Auto' scan mode, all the channels are scanned
and displayed automatically one channel after another and if
the user desires to view any particular channel for a long time,
by pressing the 'HOLD' switch, the same can be done. The front
panel accessible trim pot can adjust the scan rate time. Normally,
the standard scan rate time or 'DWELL' time can be adjusted
from 2 to 20 seconds. However, larger scan rate time can be
given on request. The other unique and useful in this instrument
is if any channel is unconnected or any sensor is open and when
that particular channel is encountered during the scan, the
same is 'Auto-skipped' i.e. the status of the channel is displayed
for the minimum time of the scan rate insted of the preset scan
rate time.
High input impedance of each channel ensures long-term measurement
accuracy. A double-pole Butterworth low pass filter and RF suppression
network is included in the circuitry to handle noisy industrial
environments.
