Red Lion Automation Series Large Display for Strain Gage Inputs PRODUCT HIGHLIGHTS > 2-1/4 and 4-inch red LED display options > Accepts strain gage, load cells and pressure inputs > Dual setpoint control > Rugged, aluminum NEMA 4X case construction > RS232/RS485 communication 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.

ADLD0378 111813 © 2013 Red Lion Controls Large Display Strain Gage Specifications AIR PRESSURE STABILIZATION VENT (57.15) 2.25 X Z Y DSP PAR RST MIN MAX TOT 1 2 GENERAL DESCRIPTION The Large Display is a versatile display available as a strain gage meter with scaling, serial communications and dual relay outputs. The 5 digit displays are available in either 2.25" or 4" high red LED digits with adjustable display intensities. The 2.25" high models are readable up to 130 feet. The 4" high models are readable up to 180 feet. Both versions are constructed of a Type 4X/ IP65 enclosure in light weight aluminum. All models also come with dual Form C relay outputs and RS232 / RS485 serial communications. The Crimson software is a Windows based program that allows configuration of the LD meter from a PC. Crimson offers standard drop-down menu commands, that make it easy to program the meter. The meter’s program can then be saved in a PC file for future use. Crimson software can be downloaded at www.redlion.net.
