The Laumas TLB is a compact DIN-rail weight transmitter with a single load cell, a 6-digit LED display, and support for up to 8 load cells. NTEP and Measurement Canada approved for legal-for-trade use, it communicates via RS485 and supports multiple fieldbus options.
The TLB is a versatile, space-saving weight transmitter designed for DIN-rail mounting in control cabinets. Its slim vertical profile makes it the practical choice when panel real estate is at a premium, while its 24-bit A/D converter and up to 300 conversions per second deliver the precision and speed required in dynamic industrial weighing applications.
With NTEP (nmax 5000, Class III) and Measurement Canada approval, the TLB is a certified legal-for-trade instrument for commercial weighing in both the United States and Canada – making it suitable for retail trade scales, vehicle weighing, and regulated process weighing. It connects to PLCs via a 16-bit optoisolated analog output or through any of its available fieldbus options: Modbus RTU, Modbus TCP, Ethernet/IP, PROFINET IO, Profibus DP, EtherCAT, CANopen, DeviceNet, CC-Link, POWERLINK, SERCOS III, EtherCAT, and Ethernet TCP/IP.
The TLB supports up to 8 load cells in parallel via a junction box, real and theoretical & real calibration up to 8 linearization points, gross weight zero tracking, semi-automatic tare and zero, preset tare, and peak weight display. Configuration and management are handled via the free Instrument Manager PC software.
Most Common Applications: Platform and floor scales, conveyor scales, tank and silo weighing, filling and batching systems, commercial trade scales, process control and automation.
