TLB4 Analogue Weight Transmitter

Laumas TLB4 Analogue weight transmitter

With four separate load-cell inputs, the Laumas TLB4 Analogue gives engineers more information than a single combined junction-box signal. Digital equalisation simplifies corner adjustment and individual channel readings help with fault finding.

Its main interface is a configurable analogue output, making it a practical choice for existing PLCs, indicators and control systems that accept an analogue weight signal. The result is a useful option for OEM panels and plant upgrades where four-channel diagnostics matter.

Relay outputs, digital inputs and an RS485 service connection are included for local functions and commissioning. Confirm the load-cell arrangement and Analogue network configuration when specifying the transmitter.

FAQs

What does the Analogue TLB4 add to a weighing system?

It combines four-channel monitoring and digital equalisation with a Analogue connection to the control system.

How does digital load cell equalisation improve weighing accuracy?

Digital equalisation allows load cells to be balanced electronically, improving weighing consistency.

What applications is the TLB4 commonly used in?

TLB4 transmitters are commonly used in tanks, silos, hoppers and process weighing systems.

What makes the TLB4 different from a traditional junction box?

The TLB4 provides digital equalisation, diagnostics and individual load cell monitoring rather than passive signal summing.
