Linear correction technology is used to adjust the analog signal, ensuring high precision. Product overview: The MPM484A/MDM484A intelligent digital pressure/differential pressure transmitter controllers are intelligent devices equipped with an RS485 bus interface; they enable on-site pressure display and provide standard pressure signal outputs. It is designed to facilitate automated technical upgrades for applications that require the use of relative sets of pressure measurement points on-site. It maintains the same appearance as a pressure gauge, allowing for on-site display of pressure values, etc. It also features RS485 bus functionality for network and digital signal transmission, as well as remote setting and calibration of transmitter parameters. In addition, it provides pressure contacts and standard analog signals. Suitable for the measurement of pressure/differential pressure of fluid media and automated technical upgrades in industries such as hydropower, metallurgy, petrochemicals, urban water supply and drainage, and environmental protection. Product features: Designed with a Φ100 dimension, it can directly replace pointer-type electrical contact pressure gauges. It features an RS485 half-duplex communication interface, which facilitates network formation and data transmission, enabling remote adjustment and setting of parameters such as the product’s zero point, full scale, display value, and control contacts. On-site, it provides four-digit LED digital pressure display as well as status information display. Linear correction technology is used to process analog signals, ensuring high accuracy. It offers up to five control contacts, with the contact values and states being adjustable for precise control ； A hysteresis value can be set for the control contacts to eliminate contact jitter, ensuring reliable control. Parameters of the transmitter can be adjusted on-site using buttons, and passwords can be set, making operation convenient. It features various pressure interfaces, multiple power supply options, as well as signal outputs, allowing users to make flexible choices
