Price 74.03 EUR no VAT

The digital length counter LMD6-1/12-24V is a microprocessor device with a 6-digit display. It can measure lengths up to 999999 meters and has one output relay. By setting the conversion factor "C" the received electrical impulses in the counter are converted into a linear length. The length counter has a floating point and can indicate "m", "dm", "cm" and "mm". Programmatically can be set various parameters defining the operation of the counter. The device has an energy-independent memory. The length counter is designed for installation in a dashboard (panel montage).

FEATURES

The LMD6-1 digital length counter is designed to measure the linear length of fabrics, pipes and other materials, which in their movement rotate a control roller, from which by certain sensor electric impulses are sent to the input of the counter. For each pulse, the counter adds the value of the coefficient "C" to the total measured length. The coefficient "C" is set by the operator in advance when setting the counter. The location of the decimal point of the display can be set so that the length is displayed in meters (m), decimeters (dm), centimeters (cm) or millimeters (mm). In the counter it is possible to set a limit length "L" when reaching which the output relay of the counter turns off.
