Description This voltage logger can measure and record analog voltage from: to: in: 120 mV DC 38.4 V DC 32 user selectable ranges
Applications • Monitoring transducer outputs • Checking process control signal • Recording speed • Vibration monitoring • Providing laboratory data
How it Works • The logger converts the analog signal to a digital value using a 2.5 V reference • The digital values are processed into voltage units by an equation in TrendReader Software
Available Ranges Some of the possible 32 ranges that can be selected
Connection • Connect the wires as shown • Set the proper range in the OWL using the TrendReader Software • Start logging
Specification • Range • Max Voltage • Input Impedance • Cable 0 to 38.4 (32 ranges) ±40 VDC > 100 K 2 m (6ft) with PVC jacket to IP67 connector IP67
Selecting Transducers • The OWL is compatible with most of the transducers since it has: • Input range selection • High input impedance (> 100 K)
Three Wire Transducer Vin Common SIGNAL Three connections
Four Wire Transducers • Line Type The isolated supply appears as a line operated or isolated common that has no electrical connection to the output
Four Wire Transducers • Wheatstone Bridge Type The bridge transducer provides a differentialoutput (+/-) usually in millivolt range
