TLKWF WiFi Weight Transmitter

Name: TLKWF WiFi Weight Transmitter
Brand: Laumas
Price: 286.00 GBP

Laumas TLKWF Wi-Fi weight transmitter

The TLKWF combines load-cell signal processing, a local display and Wi-Fi communication in an enclosed unit. It suits weighing installations where operators need to see the weight at the equipment while data is also made available through a compatible wireless network.

A backlit display and four-key keypad support local setup and checking during commissioning or maintenance. The enclosed format is useful beside tanks, hoppers, platforms and machinery where a panel-mounted DIN-rail transmitter would be less convenient.

Check Wi-Fi coverage, network compatibility, enclosure requirements and the load-cell connection before ordering. Wireless performance will depend on the installation and surrounding equipment.

Applications

Wireless tank and hopper weighing

Provide a local weight display while passing data through a compatible Wi-Fi installation.

Sites where communication cabling is difficult

Reduce the need for a new serial data cable between compatible parts of the weighing system.

Remote process monitoring

Make weighing information available to compatible networked equipment without losing local indication.

Weighing-system upgrades

Add Wi-Fi communication to a suitable load-cell installation while retaining local setup controls.

Features

Integrated Wi-Fi communication

The TLKWF provides wireless communication for compatible Laumas weighing and control systems.

Local display and keypad

A backlit two-line LCD and four-key keypad allow the weight and setup information to be checked locally.

Protected field enclosure

The electronics are housed in an IP67 wall-mounted case with sealed cable entries.

Serial connectivity

RS232 and RS485 connections support compatible serial equipment as well as the Wi-Fi link.

FAQs

Does the TLKWF measure the load-cell signal?

Yes. It is a weight transmitter with local indication and Wi-Fi communication.

Does it still have wired serial connections?

Yes. The TLKWF includes RS232 and RS485 communication for compatible serial equipment.

Will Wi-Fi work in every industrial building?

Not necessarily. Metalwork, machinery, distance and network configuration can affect coverage.

Can the TLKWF be mounted beside the weighing system?

Yes, subject to site conditions; it uses a wall-mounted IP67 enclosure.
