BLH Nobel Instrument AST 3P

AST 3P

The weight transmitter AST 3P is a BLH NOBEL weighing instrument that guarantees high performance. It has been designed for applications with strain gage transducers that can convert the output of connected load cells into a very stable signal suitable for PC or PLC. The set up procedure and the calibration of the AST 3P BLH NOBEL weighing instrument are easy to set up. ART 3P may also have 2 digital inputs as optionals (24 Vdc/ac 6mA).
