OMYL-M41_OMYL-M42

OMYL-M41 (one pulse input channel) and OMYL-M42(two pulse input channels) data loggers are designed tomeasure potential-free (dry contact) pulses or voltagesignals up to 3V using the included OMYL-CS inputcable. With the optional OMYL-CP connection cable thelogger can be used for measuring signals up to 24V.These data loggers are available with standard memory of100,000 readings (OMYL-M41, OMYL-M42) or expandedmemory of 4 million readings (OMYL-M41-4M,OMYL-M42-4M).

These devices are fully programmable allowing you toset the data logger to record on one or two channels.The incoming signal type (potential-free or voltage) canbe set using the included software.

These data loggers are best suited for operation withcounters, photoelectric sensors, revolution-counters,make contact elements, switches and sensors such asflow meters or energy consumption meters with pulseoutput. Both data loggers can also be integrated intothe aerodynamic rain gauge OMYL-RG.

Once activated the data logger senses and records thenumber of pulses/contact closures that occur withinadjacent “time bin” periods. The bin period is selectablefrom 1 second to over 24 hours. At the end of each binperiod, the total number of pulses/counts within thebin period is recorded. The data logger thenstarts another bin period and continues untileither the memory is full or the test periodhas ended.

The storage medium is non-volatile flashmemory so no data is lost if the batterybecomes discharged. Data logger setup aswell as data retrieval is accomplished usingthe included standard OMYL-SOFT software.Downloaded data is stored in theOMYL-SOFT software as a text file forviewing in third party software packages orMicrosoft Excel. The OMYL-SOFT standardsoftware does not include any graphingfunctionality. Graphing and analyzingdownloaded data files requires theOMYL-SOFT-PLUS version of thesoftware (sold separately)
