Compression Load Cell DLC (DLC-Ex)

Capacitive load cells with integrated lift-off protection (Patent Pending) for installations e.g. in areas with seismic activity, outdoor silos and high shear mixers. These robust digital compression load cells in EHEDG compliant design are produced in electropolished stainless steel and hermetically sealed to IP68. The load cells type DLC-Ex can be used in ATEX (Ex) and IECEx applications (Zone 1, 2, 21 and 22).

Type: DLC (Non-ATEX) DLC-Ex (ATEX)

Plug-and-play interface modules

Accurate and reliable communication to PLC's, SCADA, and control systems

Our interface modules support all communication protocols on the market, including EtherNet IP, PROFINET, and EtherCat, and all our interface modules have direct fieldbus interfaces and analogue I/O.

Digital technology ensures high accuracy and resolution

When you combine Eilersen interface modules with Eilersen digital load cells, your measuring chain is purely digital. There is no loss of signal as there is no A/D conversion. As a result, you get the most accurate measurement and the highest resolution possible.

Standard or customized firmware

Our wide range of direct fieldbus interfaces make our interface modules easy to connect to your existing PLC’s and control systems. Besides standard firmware, all products can be delivered with customized firmware to suit your needs.

Monitor up to 16 load cells from one interface module

The integrated monitoring provides data of loads on the individual digital load cells and even offer integrated diagnostics. Even though Eilersen load cells don’t require regular maintenance, this feature makes troubleshooting fast and easy should the need for maintenance occur.

Suitable for all environments

No matter your industry or environment, we have interface modules and solutions to suit your needs. Eilersen interface modules can be delivered in ATEX and IECEx certified versions that ensure safety and reliability in demanding conditions.
