Input type and round bar type pressure transmission plate
Product details
I. Overview
The WH-Y301 4~20mA two-wire intelligent pressure transmission board, with a highly integrated circuit centered around a microprocessor, reliably collects and processes pressure signals as well as outputs in a loop. It also provides a single bus digital interface for fully digital debugging and calibration. Specially suitable for the production and manufacturing of low-cost, compact pressure and liquid level transmitters using diffused silicon, ceramics, and strain gauges.
