Digital length counter LMD8-2R/220V
L1=(0 ... 99999999 m), L2=(0 ... 999999 m), Us=220Vac, 190x120x60mm
The LMD8-2R/220V digital length counter is a microprocessor device with two digital displays - one 8-digits and one 6-digits. The counter is reversible and can add and subtract lengths. It has two inputs "A" and "B" and operates together with an encoder type "NPN". The device has an energy-independent memory. The length counter is specialized for use in the textile industry in the classification of fabrics.
FEATURES
The reversible digital length counter LMD8-2R is designed to operates with an encoder (photoelectric raster converter) or with a sensor with two phase-shifted outputs type "NPN". It serves for measuring the length of fabrics and other materials in their classification. There are two displays on the front panel - 8-digit to measure the total length of the material and 6-digit to measure the length of the defective material. The counter has two independent memories - "Summational" and "Total". The "Summational" memory stores the accumulated lengths of the measured material for a short period of time (day, week, month). The "total" memory serves to store the accumulated lengths for a longer period of time (year, for annual reporting). The coefficient "C" is set programmatically, which serves to convert the electrical pulses received at the input of the counter into real length. The coefficient "C" determines the discreteness (step) when measuring the length of the material.
