The OMYL-M90 and OMYL-M90E are temperature/ humidity data loggers that also accept two universal external inputs and are software configurable to record up to 6 parameters. These data loggers are available with standard memory of 100,000 readings (OMYL-M90, OMYL-M90E) or expanded memory of 4 million readings (OMYL-M90-4M, OMYL-M90E-4M).

The following inputs can be configured:

  • Temperature and humidity (internal sensors for OMYL-M90, integral temperature/humidity probe for OMYL-M90E)
  • External temperature (Pt100/Pt1000 RTD, U thermistor)
  • External temperature/humidity (for combined external temperature/humidity probes)
  • Process voltage or current (0 to 10 mV, 0 to 20 mV, 0 to 50 mV, 0 to 100 mV, 0 to 1 V, 0 to 2.5 V, 0 to 5 V, 0 to 10 V, 0 to 24 mA)
  • Pulse or frequency input, e.g., from revolution counters, rain gages, photoelectric sensors

For pulse input 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 (ordered separately).
