Description
Description
The OMYL-M90 and OMYL-M90E are temperature/humidity data loggers that also accept two universalexternal inputs and are software configurable to recordup to 6 parameters. These data loggers are availablewith 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 inputscan be configured:• Temperature and humidity (internal sensors forOMYL-M90, integral temperature/humidity probe forOMYL-M90E)• External temperature (Pt100/Pt1000 RTD, U thermistor)• External temperature/humidity (for combined externaltemperature/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 sensorsFor pulse input once activated the data logger sensesand records the number of pulses/contact closures thatoccur within adjacent “time bin” periods. The bin period isselectable from 1 second to over 24 hours. At the end ofeach bin period, the total number of pulses/counts withinthe bin period is recorded. The data logger then startsanother bin period and continues until either the memoryis full or the test period has ended.The storage medium is non-volatile flash memory sono data is lost if the battery becomes discharged. Datalogger setup as well as data retrieval is accomplishedusing the included standard OMYL-SOFT software.Downloaded data is stored in the OMYL-SOFTsoftware as a text file for viewing in third party softwarepackages or Microsoft Excel. The OMYL-SOFTstandard software does not include any graphingfunctionality. Graphing and analyzing downloaded datafiles requires the OMYL-SOFT-PLUS version of thesoftware (ordered separately).
