Laumas TLB Weight Transmitters

Laumas TLB weight transmitters are compact DIN rail weighing transmitters designed for industrial automation, PLC integration and process weighing applications. Suitable for load cell systems used in batching, silo weighing, hopper weighing and process control, the TLB series provides reliable signal conversion and stable weight data transmission for demanding industrial environments.

Output selection guide

Choose your Laumas TLB connection

Match the transmitter to the input or communication protocol required by your PLC, display or control system. Select an option below to view the product and check its full specification.

TLB Analogue: Current or voltage input Confirm the required signal range and weight scaling.
TLB RS485: Serial communication Confirm the required protocol, address and baud rate.
TLB Ethernet TCP/IP: TCP/IP communication Check the supported communication method against your receiving software or controller.
TLB EtherNet/IP: EtherNet/IP network Choose for a controller configured to use EtherNet/IP.
TLB Modbus TCP: Modbus TCP network Choose for a controller or monitoring system using Modbus TCP.
TLB PROFINET IO: PROFINET IO network Match the transmitter to the machine's PROFINET IO requirements.
TLB PROFIBUS DP: PROFIBUS DP network Choose for an existing or specified PROFIBUS DP system.
TLB EtherCAT: EtherCAT network Choose for a controller using EtherCAT communication.
TLB CANopen: CANopen network Confirm CANopen support in the receiving controller.
TLB CC-Link: CC-Link network Check the specified CC-Link network and controller requirements.
TLB DeviceNet: DeviceNet network Choose for a machine or control system using DeviceNet.
TLB POWERLINK: POWERLINK network Choose for an automation system using POWERLINK.
TLB SERCOS III: SERCOS III network Choose for a controller using SERCOS III communication.

Check the exact protocol: Ethernet TCP/IP, EtherNet/IP and Modbus TCP are different options. An Ethernet connection alone does not establish compatibility.

One weighing channel: These TLB models read one load cell or the combined signal from several compatible cells connected in parallel through a junction box, subject to electrical limits. For individual load-cell monitoring, consider TLB4 transmitters or TLM8 transmitters.

Where the Laumas TLB fits

The Laumas TLB is a DIN-rail transmitter for bringing one weighing signal into a PLC, display or control system. It suits installations that need the total weight from a weighing point rather than separate readings from each supporting load cell.

That weighing point may use one load cell or several compatible cells connected in parallel through a junction box. The permitted combination depends on the transmitter's excitation capacity and the load-cell impedance. Choose the TLB version with the output required by the receiving equipment.

Matching the output to your control system

An analogue output passes the weight as a current or voltage signal. The transmitter and receiving input must use matching signal ranges and weight scaling.

For serial communication, confirm the protocol as well as the connection. RS485 describes the electrical interface; settings such as protocol, address and baud rate also need to match.

For a networked installation, select the exact protocol required by the controller. Ethernet TCP/IP, EtherNet/IP and Modbus TCP are different options. Check the specific model's documentation before ordering.

Connecting the load cells

Check sensitivity, impedance and wiring against the transmitter specification. Where cells are combined in a junction box, the TLB receives their combined signal; it does not read each cell independently.

Installing in a control panel

Allow space for the DIN-rail unit, terminals and cable access. Choose an enclosure suited to the environment and follow the installation instructions for screening, earthing and cable routing.

Commissioning the system

Configure the weighing range and output, then check the installed system's calibration. Confirm that the PLC or display reports the correct weight before putting the equipment into service.

Laumas TLB weight transmitter applications

Typical uses for a TLB transmitter include:

Tank and hopper contents

Send the total vessel weight to a controller for stock monitoring or material-use tracking. After calibration, account for the empty vessel weight to obtain the contents weight.

Filling and batching

Provide weight feedback to a compatible controller as material is added or discharged. Feed control and stopping behaviour depend on the wider machine configuration.

Machine upgrades

Bring an existing compatible load-cell assembly into a new control system. Check the sensor wiring, supply and required output before choosing the replacement electronics.

Check these details before ordering

For a new installation or replacement, gather the following information so the correct TLB version can be selected.

Receiving equipment

Record the PLC, display or controller model and its required analogue signal or communication protocol.

Load-cell details

Provide the number of cells, their model numbers, sensitivity and impedance, plus details of any existing junction box.

Panel and power supply

Confirm the available supply voltage, mounting space, enclosure conditions and approximate cable distances.

Operating requirements

State the weighing range, required response time and any control functions. For a replacement, include the existing transmitter's full model code.

Laumas TLB Weight Transmitter FAQs

Practical questions about replacement and setup.

Can I replace an existing TLB with a different communication version?

Only if the replacement works with the receiving equipment and the rest of the installation. A similar case or model name does not guarantee compatibility. Check the complete model code, wiring and configuration before ordering.

Does fitting a TLB automatically calibrate the weighing system?

No. Configuration and calibration must suit the installed load cells and mechanical assembly. Check the complete system after installation or replacement; a component specification alone does not establish the accuracy of the finished system.

Will filtering fix an unstable weight reading?

Filtering can smooth fluctuations, but it does not correct faults such as binding supports, damaged wiring or poor connections. Investigate the cause first, then set filtering to suit the response time the process needs.

What should I send GNW for help choosing a replacement?

Send photographs of the existing transmitter label and connections, the load-cell details and the PLC or display model. Include the required output and any available wiring diagrams.
