Signal Level Options:
4~20 mA:The primary signal output from pressure sensors,ideal for direct measurement data transmission.
0~5 V:A converted signal from 4~20 mA,suitable for long-distance communication.
0~10 V:A higher-level signal derived from 0~5 V,designed for environments with electrical noise,such as energy industries or large server systems.
RS485:A robust communication protocol that transmits measured signals over the RS485 hardware platform.It supports remote one-to-many control and signal acquisition via the 485 bus,adhering to the ModBus RTU standard protocol.
