Descripción
The PLT-HPT-32, a new cryogenic temperature monitor, has been developed
by the Institute of Astrophysics of the Canary Islands (IAC) and an
external engineering company (Sergio González
Martín-Fernandez). The PLT-HPT-32 temperature monitor offers
precision measurement in a wide range of cryogenic and
higher-temperature applications with the ability to easily monitor up to
32 sensor channels. It provides better measurement performance in
applications where researchers need to ensure accuracy and precision in
their low cryogenic temperature monitoring. The PLT-HPT-32 supports PTC
RTDs such as platinum sensors, and diodes such as the Lake Shore DT-670
Series. Used with silicon diodes, it provides accurate measurements in
cryo-cooler applications from 16 K to above room temperature. The
resolution of the measurement is less than 0.1K. Measurements can be
displayed in voltage units or Kelvin units. For it, two different tables
can be used. One can be programmed by the user, and the other one
corresponds to Lake Shore DT670 sensor that comes standard. There are
two modes of measuring, the instantaneous mode and averaged mode. In
this moment, all channels must work in the same mode but in the near
future it expected to be used in blocks of eight channels. The
instantaneous mode takes three seconds to read all channels. The
averaged mode takes one minute to average twenty samples in all
channels. Alarm thresholds can be configured independently for each
input. The alarm events, come from the first eight channels, can
activate the unit's relay outputs for hard-wired triggering of other
systems or audible annunciators. Activate relays on high, low, or both
alarms for any input. For local monitoring, "Stand-Alone Mode", the
front panel of the PLT-HPT-32 features a bright liquid crystal display
with an LED backlight that shows up to 32 readings simultaneously. Plus,
monitoring can be done over a network "Remote Control Mode". Using the
Ethernet port on the PLT-HPT-32, you can keep an eye on temperatures,
log measurement and configured remotely via a Networked local PC or even
remotely over a TCP/IP Internet connection from anywhere.
