Logging Time Meters
These Logging Time Meters record the amount of time an electrical
device is on. Infrared technology is used to transmit data
to a handheld reader for subsequent transfer to a computer
serial port . Eliminates redundent manhours and mistakes
copying and entering data.
UDL
This Universal Data Logger allows logging of serial data
into one mega-byte of storage. Allows data to be presented
to spreadsheet programs for load analysis. Maskable and
multiple interval selection.
LOGGING TIME METERS
Time of use.
Infrared transmission of data.
LTM-OIR Optical detector for lighting applications. High
ambient light imunity
LTM-MIR Magnetic detector for use with zip cords, wires
behind walls, and motors.
LTM-HR Handheld infrared reader used to gather, display,
and store data for transport to office computer.
Easy to install, Easy to use.
These Light Time Meters (LTMs) are instruments designed
to record the amount of time an electrical device is turned
on. An LTM uses lithium batteries to supply operating power
for 3 years. Time is accumulated with a resolution of one
second and passed, along with a 4 digit identification number,
to handheld readers via infrared transmission.
The hand-held reader then conditions the time for display
in the desired format of XXXXX.X, giving hours and tenths
of hours. The LTMs are non-resetable and all weigh less
than 4 ounces. A visual red LED and an infrared transmitter
are integral parts of each LTM
UDL
The UDL(Universal Data Logger) is a portable, one-megabyte
memory, storage device that records input data from up to
two RS232 transmitting devices. Recorded data can then be
downloaded to a computer file for subsequent viewing or
for input into a spreadsheet program. The UDL is self contained
and programmable from its' own front panel.
The UDL filters the incoming data, records the data at programmable
time intervals, then Time/Date stamps the record event.
The UDL has the ability to filter out selected fields of
incoming data as instructed by a user-programmable mask.
The mask also allows for definition of input field delimiters.
The user also sets up the desired interval for logging.
This allows the user to log only the data fields needed
at a desired interval thereby conserving memory and reducing
the overall size of a file.
Primary power is provided by a 120-volt
AC to 12VDC adaptor. Supplemental power is provided by four
AA batteries.

UDL
UDL Picture
The UDL(Universal Data Logger) is a portable, one-megabyte
memory, storage device that records input data from up to
two RS232 transmitting devices. Recorded data can then be
downloaded to a computer file for subsequent viewing or
for input into a spreadsheet program. The UDL is self contained
and programmable from its' own front panel.
The UDL filters the incoming data, records the data at programmable
time intervals, then Time/Date stamps the record event.
The UDL has the ability to filter out selected fields of
incoming data as instructed by a user-programmable mask.
The mask also allows for definition of input field delimiters.
The user also sets up the desired interval for logging.
This allows the user to log only the data fields needed
at a desired interval thereby conserving memory and reducing
the overall size of a file.
Primary power is provided by a 120-volt
AC to 12VDC adaptor. Supplemental power is provided by four
AA batteries.
