Intelligent Loadcell Amplifier

Auto calibration Remote tare, printer and reset inputs 4 to 20mA and 0 to 10V output as standard ABS case sealed to IP65 Password protection of calibration This intelligent self contained loadcell amplifier is designed for use with strain gauge loadcells. It provides industry standard current, voltage or serial data signals for accurate interfacing of loadcells with control and monitoring systems. All set up functions are via the programming module using a simple menu system. The module can be mounted on the amplifier board or supplied as a separate hand held unit for use with more than one amplifier. All parameters are set digitally for accuracy, including the analogue output. The 4 to 20mA and 0 to 10V outputs can both be used at the same time but only one can be accurately calibrated. See the LCA15 specification for more information. The normal set-up is to calibrate the 4 to 20mA output accurately unless special instructions are given with an order. The analogue output is uni-polar so if a bi-directional loadcell is used the only way to scale the amplifier is to set the mid-point of the analogue output equal to zero load. This will be 12mA or 5V. This amplifier is used throughout the process industry providing a local transmitter for process vessels and within the engineering industry for single or multiple loadcell applications. An option is available for RS232/RS485 serial communication single links or multi-drop applications of up to 25 weigh stations
