1. INTRODUCTION
PRODUCT DESCRIPTION
The SCM10 single channel monitor provides the accuracy, resolution and
interface features of a bench top temperature monitor in an easy to use,
compact and easily integrated instrument. With appropriate sensors, the SCM10
measures temperature from 1.4K to 800K and in difcult sensing conditions,
including high vacuum and magnetic elds. SCM10 has two programmable
alarms, two relays and a user congurable analog voltage or current output.
Serial interface and Ethernet interface are provided for remote operation.
A PC-compatible utility software is provided with the SCM10. This graphical user
interface provides an easy way to set all instrument parameters and evaluate
the performance of the instrument. The SCM10 also has an embedded web
server that can be used to connect to the instrument from anywhere within the
LAN using an internet browser. The instrument web page shows the current
temperature reading and shows the status of all alarms and relays.
The SCM10 Temperature Monitor supports diode and RTD sensors. The
instrument can be congured for the appropriate sensor type using the
front panel or the utility software. Two convenient sensor excitation currents
are provided to choose from. The SCM10 provides a 4 –leaded differential
measurement for accurate temperature measurements. Measurements are
available in temperature units K, ˚C or ˚F , or sensor units V or Ω.
The SCM10 has 9 standard sensor curves that are programmed into the
instrument from the factory. It also provides room for one 200 point user curve,
which may be loaded into the instrument using the utility software.
With a serial, Ethernet, and convenient graphical user interface, as well as an
ASCII command set and LabVIEW™ drivers, the SCM10 can be used as a
stand-alone temperature monitor or can be easily integrated into other systems.
