Zedflo Australia  presents the new standard in loop calibration with the Martel LC-110 and LC-110H loop calibrators.

A range of mA (loop) calibrators designed to take the loop calibrator class to the next level, the new LC-110 series features a user-friendly interface with dedicated buttons and a rotary encoder to dramatically reduce the time taken to measure, or source voltage or current and power up a loop.

The LC-110H differs from the standard LC-110 in that it incorporates HART communications and supports a select set of HART universal and common practice commands, enabling the loop calibrator to also be used as a communication tool.

In the communicator mode the user will be able to read basic device information, perform diagnostic tests, and trim the calibration on most HART enabled transmitters. The LC-110H will allow many more technicians to service and support HART devices. In addition to HART communications, users can also get information out of the LC-110H.

To quickly document the parameters of all the HART transmitters in the plant, the user has to simply add the BetaLOG HART software/cable to capture and upload up to 20 configurations in (.csv) or (.txt) format.

Key features of new LC-110 series loop calibrators:

  • Best in class accuracy at 0.01% reading
  • Rugged case contoured to easily fit a technician’s hand
  • Large backlit graphics LCD
  • Operates on (6) standard AAA batteries
  • Intuitive interface features a Quick-Set Knob
  • 24VDC loop power with mA Measure Mode (-25% to 125%)
  • Resolution of 1μA on mA ranges and 1mV on voltages ranges
  • Built-in selectable 250Ω resistor for HART communications
  • Simple 2-wire connection for all measurements
  • Variable step & ramp time in seconds
  • Adjustable span selection (0 to 20mA or 4 to 20mA)
  • Valve test (simulate defined mA values with % keys)
  • Data log tool features selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions
