LCA20 Intelligent Load Cell Amplifier

The LCA20 intelligent strain gauge amplifier offers both 4 to 20mA and 0 to 10 volt analogue outputs, from any standard strain gauge input. One pass calibration and setting of the analogue output range make the unit extremely user friendly; being set up by a simple hand held or on-board programmer/display. Auto Tare and Peak Hold (if set) on the analogue output are operated via volt free contact closures, and output options include relay set points programmed in engineering units, with in flight compensation and hysteresis settings are available for control or alarm purposes.

The LCA20 features RS232 and RS485 digital data output for communications and printing, and firmware now supports Mantrabus 1&2, Mantra ASCII 2 and Modbus RTU. Printing can be actioned by a contact enclosure, and the printer can print the current live value, with header message, engineering units, auto incrementing batch number and in real time if required (using a printer with time/date facility)

The LCA20 also enable selection of device parameters via a PC or keypad rather than using the traditional on-PCB switches.
