Esmacat 16CH Loadcell Interface

Simple EtherCAT-Based Loadcell Sensor Interface

Obsolete as of May 2022

The Esmacat 16CH Loadcell Interface is the easiest, precise integrated solution to read loadcells or other strain-gauge sensors with built-in programmable amplifiers. It is capable of interfacing even 6 axis loadcells without the need for separate amplifier hardware.  Its various programmable gain amplifier (PGA) and error minimization technology, such as the 24-bit delta-sigma (ΔΣ) modulator and on-board calibration, ensure the precision of measurement allowing 16 bit effective resolution. Power-over-EtherCAT (POE) technology allows high speed communication and flexible connectivity by supporting daisy-chain wiring. The 16Ch Loadcell Interface is a part of the Esmacat suite and is the ideal interface solution for both novice and expert Robotics engineers due to its compact size, easy programmable master software, and hardware setup.

*Note: The Esmacat 16CH Loadcell Interface uses a PoE input voltage rating of 24VDC. Please see datasheet for more details.*

Incorporating the Esmacat 16CH Loadcell Interface Into Your Project

We have plenty of supporting material on our tutorials page, including this YouTube video and many more, on how to get started with the 16 CH Loadcell Interface. All our material uses the Esmacat Master software for simple setup but the 16 CH Loadcell interface is compatible with all EtherCAT masters via a few extra steps. 


Master Software

Esmacat provides EtherCAT master software to control the motor driver (position control and velocity control included) through a daisy-chain topology filled with Ethernet cables from an EtherCAT master. Our free open-source master software compatible on both Windows and Linux can be found on our Software page. Our loadcell interface is also compatible with 3rd party EtherCAT master devices.
