TLK Serial Weight Transmitter


Laumas TLK serial weight transmitter

The TLK is an enclosed weight transmitter with a local display and keypad for setting up and checking a load-cell weighing system. Its serial communication makes it suitable for installations where weight data must be passed to a compatible controller, display or supervision system.

The field enclosure provides a convenient alternative to a bare DIN-rail module when the transmitter needs to be mounted near a tank, hopper, platform or machine. The display allows an engineer or operator to see the measured value locally during commissioning and routine checks.

Confirm the required serial protocol, enclosure protection and load-cell arrangement before ordering, particularly when replacing an existing transmitter.

Applications

Tank and hopper weighing

Mount the transmitter near the vessel for local indication and serial transfer of weight data.

Platform weighing systems

Connect a load-cell platform to a controller while retaining a visible display beside the equipment.

Machine and process integration

Pass weight data to compatible PLCs, HMIs or supervision equipment through RS232 or RS485.

Replacement and upgrade projects

Use the enclosed format where a field-mounted serial transmitter needs to be replaced or modernised.

Features

Local weight display

The two-line backlit LCD lets an operator or engineer view the measured value at the installation.

RS232 and RS485 communication

Serial ports support connection using Modbus RTU or the Laumas ASCII protocol.

Protected wall-mounted enclosure

The IP67 case is designed for mounting near tanks, hoppers, platforms and industrial machinery.

Inputs and relay outputs

Two digital inputs and four relay outputs support compatible alarms, setpoints and simple control functions.
