Description
This product line has been discontinued. For an alternate product, please see our wide selection of temperature and humidity loggers here.
OMYL-M41 (one pulse input channel) and OMYL-M42
(two pulse input channels) data loggers are designed to
measure potential-free (dry contact) pulses or voltage
signals up to 3V using the included OMYL-CS input
cable. With the optional OMYL-CP connection cable the
logger can be used for measuring signals up to 24V.
These data loggers are available with standard memory of
100,000 readings (OMYL-M41, OMYL-M42) or expanded
memory of 4 million readings (OMYL-M41-4M,
OMYL-M42-4M).
These devices are fully programmable allowing you to
set the data logger to record on one or two channels.
The incoming signal type (potential-free or voltage) can
be set using the included software.
These data loggers are best suited for operation with
counters, photoelectric sensors, revolution-counters,
make contact elements, switches and sensors such as
flow meters or energy consumption meters with pulse
output. Both data loggers can also be integrated into
the aerodynamic rain gauge OMYL-RG.
Once activated the data logger senses and records the
number of pulses/contact closures that occur within
adjacent “time bin” periods. The bin period is selectable
from 1 second to over 24 hours. At the end of each bin
period, the total number of pulses/counts within the
bin period is recorded. The data logger then
starts another bin period and continues until
either the memory is full or the test period
has ended.
The storage medium is non-volatile flash
memory so no data is lost if the battery
becomes discharged. Data logger setup as
well as data retrieval is accomplished using
the included standard OMYL-SOFT software.
Downloaded data is stored in the
OMYL-SOFT software as a text file for
viewing in third party software packages or
Microsoft Excel. The OMYL-SOFT standard
software does not include any graphing
functionality. Graphing and analyzing
downloaded data files requires the
OMYL-SOFT-PLUS version of the
software (sold separately)
