LCB Load Cell Digitizer

Q: What does the Laumas LCB do?

It converts the analogue millivolt-per-volt signal from a strain-gauge load cell into a digital signal for a compatible control system.

Q: Does the LCB include a load cell?

No. It is a separate digitiser used with a compatible analogue load cell or strain-gauge sensor.

Q: Which communication version should I choose?

Choose the variant that matches the protocol used by the PLC or control system.

Q: Which enclosure material do I need?

Plastic suits general industrial use; stainless-steel and hygienic versions suit more demanding environments.

Applications

Retrofitting existing load cells

Add a digital interface to a compatible analogue load cell without replacing the sensor.

PLC-connected weighing machinery

Send load-cell data directly to machinery using the industrial communication protocol specified by the control system.

Tank, hopper and silo weighing

Digitise the signal close to the vessel where long analogue cable runs would otherwise be required.

Washdown and hygienic installations

Select the appropriate stainless-steel or hygienic housing for food, pharmaceutical and frequently cleaned equipment.

Features

Converts analogue load cells to digital

The LCB converts the millivolt-per-volt output from an analogue strain-gauge load cell into a digital signal close to the measurement point.

Choice of industrial interfaces

Variants are available for CANopen, EtherNet/IP, EtherCAT, IO-Link, Modbus TCP, POWERLINK, PROFINET IO, SERCOS III and CC-Link IE Field Basic.

Enclosures for different environments

Choose reinforced plastic, AISI 304 stainless steel or a hygienic stainless-steel version to suit the installation.

Compact field installation

IP67 construction, M12 connections and status LEDs support installation near the load cell while keeping the low-level analogue cable run short.
