The ERX 350 is an End-of-Line, Low Pressure Point, District Regulator, System Pressure Monitoring, Recording and Alarming instrument.
Honeywell’s ERX 350 Electronic Pressure Recorders are intended to simplify and optimize pressure monitoring applications. This new Pressure Recorder, based on the EC 350 electronic corrector platform offers best-in-class accuracy, expanded memory, advanced diagnostics and integrated cellular communications. The ER 350 also reduces maintenance requirements and is intuitive and simple to use.
How Does It Work?
The 350 series provides many operational advantages. These flexible devices have a common look and feel, and utilize state-of-the-art technology such as a 4G modem. They also incorporate a highly accurate, plug-and-play digital pressure transducer and an enclosure optimized for serviceability. Featuring long-term stability and extended battery life, the ER 350 minimizes the need for site visits and simplifies field repairs.
Best of all, the ER 350 utilizes the same user interface as our field proven EC 350. It also uses a robust latching and locking mechanism similar to the ERX standard for ruggedness and reliability.
What Problems Does It Solve?
The ERX 350 simplifies pressure monitoring applications. It is typically installed at the End of gas lines, at Low Pressure Points, District Regulators and are intended to monitor system pressures, record and alarm.
