Red Lion LD2SG5P0 Large display for strain gage input Datasheet

Large Display Strain Gage
Red Lion Automation Series
Large Display for Strain Gage Inputs
Red Lion’s Large Display Strain Gage (LDSG) is
the latest addition to our Large Display portfolio
for advanced control and communication of
weight measurement.
Available in both large 2-¼ and 4-inch display sizes, the LDSG accepts most
load cell and strain gage inputs and communicates real-time weight information
to a database or management system for accurate monitoring, storage and
reporting. By using alarming setpoints and a display that is readable from
distances up to 180 feet away, operators are automatically alerted and can
easily see when weight limits are being approached or exceeded.
With easy, push-button setup and NEMA4X/IP64 sealed enclosure design,
LDSG implementation is simple. Once installed, weight values can be collected
in real time and used later via its RS232/RS485 serial communication ports.
The end result provides the reliability and ease of use required to improve
efficiency and reduce costs by increasing weight measurement accuracy.
