techniCAL | LC-110H Loop Calibrator Kit with HART Communications & Diagnostics

Description

Does your loop calibrator talk to HART devices? Why not?

The Martel LC-110H mA (loop) calibrator is designed to take the loop calibrator class to the next level. The LC-110H differs from the standard LC-110 in that it incorporates HART communications and supports a select set of the HART universal and common practice commands. This unique feature allows the LC-110H to be used as both a loop calibrator and 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. In the past, this could only be done with a dedicated communicator, high-end multifunction calibrator costing thousands of dollars, or a laptop computer with HART modem. The LC-110H will allow many more technicians to service and support HART devices.In addition to HART communications, we also gave the user the ability to get information out of the LC-110H. Need to quickly document the parameters of all the HART transmitters in your plant? Just add the BetaLOG HART software/cable to capture and upload to twenty configurations in either (.csv) or (.txt) format.If you don’t need the HART capability, check out the LC-110 Precision Loop Calibrator. It features the same user friendly interface at about half the price.For a complete list of specifications, please download the MARTEL Electronics Corporation.
