HOBO Data Logger State Logger UX90-001M

Overview The HOBO State/Pulse/Event/Runtime data logger records state changes, electronic pulses and mechanical or electrical contact closures from external sensing devices. This logger is ideal for monitoring energy consumption, mechanical equipment operation, and water and gas flow. The HOBO UX90-001 State Logger is available in a standard 128 KB memory model (UX90-001) capable of 84,650 measurements and an expanded 512KB memory version (UX90-001M) capable of over 346,795 measurements. Highlighted Features One logger with 4 recording modes Internal reed switch can be used to determine when a door or window is open or closed Compatible with a wide range of external sensors Ships with 2.5 mm input cable. Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis Internal Sensor Maximum state, event, runtime frequency: 1 Hz Preferred switch state: No magnet present (normally open) External Input External contact input: Electronic solid state switch closure or logic driven voltage output Range: 0 to 3 V DC (USB powered), 0 to 2.5 V DC (battery powered) Maximum pulse frequency: 50 Hz Maximum state, event, runtime frequency: 1 Hz Pulse, event lockout time: 0 to 1 second in 100 ms steps Solid state switch closure: Input Low: lt; 10 KΩ; Input High: gt; 500 KΩ Internal weak pull-up: 100 KΩ Input impedance: Solid state switch closure: 100 KΩ pull up Logger Resolution: Pulse: 1 pulse, Runtime: 1 second, State and Event: 1 State or Event Logging rate: 1 second to 18 hours, 12 minutes, 15 seconds UX90-001- - Time and Accuracy Specification ChartTime accuracy: ±1 minute per month at 25°C (77°F) (see Plot A) Battery life: 1 year, typical with logging intervals greater than 1 minute and normally open contacts Memory UX90-001: 128 KB (84,650 measurements, maximum) UX90-001M: 512 KB (346,795 measurements, maximum) Download type: USB 2.0 interface Download time: 10 seconds for 128 KB; 30 seconds for 512 KB
