July 31, 2011 - Calex announces the Model 4720. DIN Rail mount, self-contained DC powered module designed for load cell, strain gage, or single ended analog amplification and filtering. It contains a precision instrumentation amplifier, filtered output and a built-in excitation supply. The 4720 provides a cost effective solution for applications such as conveyor weighing systems, hoppers or tank farms. The 0 to 30mV input range makes it compatible with most strain gage based load cell or pressure transducer outputs.
The built-in 10V excitation supply is capable of driving a 350 ohm bridge. The filtered output of the 4720 is 4 to 20mA with a frequency response of DC to 10Hz. Connections are made via easily accessible screw clamp terminal blocks. Zero and Span adjustment potentiometers are located externally as well for easy access.
Overall dimensions are 3.78”L x 1.06”W x 1.65”H. The 4720 is backed by Calex’s five year warranty.
