Products - Electronics
Our products are used for measurement
of viscosity and temperature in either a laboratory
or process environment. A complete system consists
of up to four pieces, 1) the measurement sensor, 2)
electronics to power and excite the sensor then interpret
and linearize the response, 3) software resident on
your computer for download of datalogs, alarm setup,
graphing, tabular history, etc., and 4) accessories
for interface to process lines, tanks, lab sampling,
temperature control, etc. A sensor with electronics
will run automatically as soon as power is applied,
so the minimum system is a sensor and a circuit card.
The client side software adds functionality and convenience.
Accessories enable easy interface to virtually any
process line configuration and convenience in the
lab for sampling and measurement.
Electronics
Our
electronics excites the sensor, then interprets the
response based on calibration coefficients stored
in flash memory. The electronics can be operated stand
alone and/or interconnected to any windows-based computer
or network through its serial port or analog outputs.
Circuitry is available in a combination bench top/wall
mount configuration with a two-line, backlit text
display of viscosity and temperature or in OEM board level configurations. All systems have either 0-4Vdc or sourced
4-20ma [jumper selectable] analog outputs for remote
monitoring or control.
Viscosity and temperature measurements are made every
200 milliseconds. Every two seconds the data is statistically
analyzed and the analog outputs refreshed. All data
is available through the serial port with date and
time code tags at intervals from 10 seconds to 10
minutes. The computer displayed data is further processed
using a rolling average of the 2 second data summaries
computed at the time of the log entry. The computer
display has easily set high and low alarm levels on
both viscosity and temperature with color coded data
entries based on proximity to alarm levels. The alarm
state is indicated on the data log as a color code
and is output on the circuit card as a 5Vdc TTL logic
level.
