Approvals

WARNING: Cancer and Reproductive Harm California Proposition 65

SCT-4XD is a high-speed integrator designed to manage up to four load cells, capable of reading two speed encoders and managing two totalizers. 

Paired with the 1280 terminal enhances usability with a resistive touchscreen and intuitive interface for real-time diagnostics and process data. Two operating modes, belt or solid flow metering, offer flexibility for different applications.

The 1280 also features a built-in web server which allows remote connection from anywhere on the network.
