Setra 231G-MS1-2F-N Pressure Transducer 319852-301 What is the difference betweenThe Setra 231G MS1 2F N represents the industry standard for wet to wet differential pressure monitoring in hydronic systems and HVAC process control. This multi configurable transducer is an all in one solution for contractors, featuring 8 field selectable pressure ranges and 4 field selectable analog outputs (4 20 mA, 0 5 VDC, 0 10 VDC, and 1 5 VDC). Built around a highly reliable piezoresistive sensor, it handles unidirectional ranges of 5, 10, 25,
