Laumas TLB Single-Channel Digital Weight Transmitter 

The Laumas TLB Weight transmitter is suitable for back panel mounting on Omega/DIN rail. Constructed in a space-saving vertical shape, with dimensions: 25x115x120 mm. It has a 6-digit semi-alphanumeric red LED display (8 mm height) and 6 signaling LED. Built with Four buttons for the system calibration and extractable screw terminal blocks.
