LT1320 Belt Weigher Indicator


The LT1320 Belt Weigher indicator is a precision digital indicator for belt weighing applications.

The LT1320 takes the weight and speed information from a belt conveyor system to accurately calculate rate and total material transferred. The high bright 6-digit 7-segment 20mm LED displays and the sunlight readable graphic LCD display make for easy setup and readability. A simple menu system allows for easy configuration of display and belt weighing settings. The load cell calibration can be done directly from the load cell calibration certificate or by using dynamic calibration of the belt conveyor system.

The LT1320 also provides an internal jumper selectable power supply for powering an encoder / tacho-generator and a pulse counting digital input to measure the speed of the belt conveyor system.
