HOBO® Family Motor on/off Light on/off State open/closed External contact closure
HOBO Family loggers record when devices change between open closed, storing time, date, state each change. your readout analyze data.
Motor on/off: AC-field sensor vibration sensing?
AC-field sensor mounting motors Magnetic field intensities fall rapidly with increasing distance from their source (motor, transformer, even single wire carrying large current). This means that logger must mounted very close (ideally directly field source. While this make less convenient attach logger, means that interference from other sources less likely.
Features specifications
Capacity: 2000 state changes Time resolution: second Minimum state duration: second Drop-proof Mounting included (hook/loop, magnet, tape) Programable start time/date Memory modes: stop when full, wrap-around when full Nonvolatile EEPROM memory retains data even battery fails Blinking lights show current state User-replacable battery lasts year Battery check launch readout Operating range: -20°C +70°C (4°F +158°F), relative humidity, non-condensing, non-fogging Time accuracy: minute week 20°C Size/Weight: 19mm (2.4 0.8")/approx. oz.) year warranty Sure-snap case
Vibration sensor convenient mounting vibration only weakly dampened distance that logger need mounted directly source. However, this leads potential interference from other sources. logger's threshold adjustment used discriminate against other sources.
Sensor specifications
Motor on/off with AC-field sensor Magnetic field threshold: Gauss logger will typically work with motors drawing more. most cases will need mounted close motor housing. Angular response: logger sensitive that part field that perpendicular logger's face.
Motor on/off with vibration sensor Vibration threshold: adjustable ~0.05 (.0001" .001" displacement). Will typically work vibration felt with your hand. Angular response: logger sensitive that part vibration that perpendicular logger's face.
Note: BoxCar (3.0 later) BoxCar Starter required operate HOBO loggers. Each starter includes software, computer interface cable software User's Manual. Only BoxCar supports HOBO Shuttle.
Light on/off Light threshold adjustment range: approx. lumens/ft2 (fluorescent light). sensitivity incandescent light about times greater.
Open/closed, contact closure (HOBO State) inputs: magnetic sensor mounted logger external input cable detecting contact closures. Spacing between HOBO State external magnet: closed 1/4"; open 3/4" (external magnet included). external contact input: relay switch contact closure.
