Method for setting the range of an adjustable pressure transmitter: detailed explanation of the lower limit, upper limit, and five-point calibration steps, covering 4～20mA signal conversion, peak pressure allowance, alarm thresholds, and on-site troubleshooting to help achieve safe and accurate measurement and control.

How should the trigger thresholds of an alarm pressure transmitter be set? This article explains how to configure high/low alarms, interlock values, hysteresis, and delays, with application examples for water supply, hydraulic systems, air compressors, and other operating conditions to help reduce false alarms and improve pressure system safety.
