The PENKO FLEX Force is a high-speed multi-channel weighing and force measurement controller in the FLEX series. It processes up to 4 independent strain gauge channels — each supporting up to 4×350Ω or 8×1100Ω load cells per channel — with 24-bit A/D conversion at 1600 readings per second and nonlinearity below 0.005% of reading. The module is designed for industrial weighing, batching, and material testing applications requiring OIML R76 legal-for-trade accuracy.

How does G-CAL automatic gravity compensation work?

Strain-gauge-based weighing systems calibrated at the factory read differently when installed at a different geographic location due to variations in gravitational acceleration. PENKO's G-CAL system allows the user to enter the target installation site's geographic coordinates; the controller automatically calculates and applies the correct gravity correction factor. This eliminates the need for on-site recalibration with certified test weights after transport or relocation — particularly valuable for mobile weighing systems and equipment shipped between continents.

What communication options does FLEX Force support?

Standard interfaces include Ethernet, USB, RS232, RS422, RS485, and CAN bus, with fieldbus protocols — Profibus DP, EtherNet/IP, Modbus TCP, and Modbus RTU — available as options. Four analog outputs (4–20 mA / 0–10 V, each with independent calibration coefficients) and expandable digital I/O (8 inputs + 16 outputs on certified versions) enable direct integration with PLCs and plant-wide automation networks. The built-in web server provides browser-based remote monitoring without additional software.
