The 1\/4 NPT thread and high range suit hydraulic systems, pump test rigs and other high-pressure applications. It works from the box on the factory 0-160 bar range, or can be rescaled down to a third of full scale (about 0-53 bar) for better resolution.\u003c\/p\u003e\n\u003cp\u003eAs with all NP640 models of 16 bar and above, this is a sealed relative transmitter, referenced to a sealed 1 bar rather than open to atmosphere.
