The i-bug and v-bug are palm sized standalone dataloggers that record current and voltage signals from industry-standard transducers, transmitters and sensors. Each unit is available as a two-channel device for logging dc voltage or 4-20mA current loop signals. The inputs of each logger are over voltage and reverse polarity protected. The i-bug has 51R1 0.1% 10ppm precision shunt resistance.

The i-bug and v-bug loggers are simple to use and configure, just connect to the two signals wires from your transmitter, transducer or sensing device to the logger’s easy to use input connectors. The process readings are stored as raw readings. Scaling is done at the PC, data can be re-scaled as necessary.

The Hanlog PC software will convert the recorded results into familiar engineering units for display, analysis and presentation. Clear and concise graphical and tabular representations of the data can then be created plus overlay graphs from different loggers and a display of data in real time. Data from multiple loggers can be grouped and exported as a single file for use in other applications.

Both the i-bug and v-bug are ideal for interfacing to any equipment supplied with dc voltage or 4-20mA current loop outputs.

Hanwell loggers have full specification RS232 comms. at 19200 Baud, while most other loggers provide only marginal levels at a much lower Baud rate. The impressive result is an entire memory download in less than 15 seconds.
