Load Weigher / Monitor

The LW20/13 is the simple, easy to use Load Monitor System employed by Lester Controls. The advent of high gain integrated amplifiers with increased stability and advanced strain gauge bonding has resulted in a highly reliable and stable load monitor. Calibration is straight forward once the lift car has been zero loaded. 90% bypass and 110% overloaded can then be calibrated accurately. A stable 24v DC power supply is required.
