DatasheetDynisco SPX Industrial Series (SPX2280 / SPX2281)
The Dynisco SPX2280 and SPX2281 pressure transmitters are intelligent, all-welded industrial transmitters designed for precise pressure measurement in demanding industrial and hazardous-area applications. The transmitters provide a standard 4–20 mA output signal and are available with optional HART® communication.
With high accuracy, extensive approvals and a 3:1 turndown capability, the SPX transmitters are ideally suited for process control systems, pressure monitoring applications and safety-related installations. The transmitters are available in gauge, absolute and differential pressure configurations and interface directly with DCS, PLC and process automation systems.
