1.General Introduction

ABB 266NSH absolute pressure transmitter is a traditional type for absolute pressure measurement, measure range from -100Kpa to 105Mpa, maximum static pressure is up to 239.7Mpa and maximum turn down ratio up to 100:1. standard accuracy is 0.06%, maximum accuracy 0.04% is optional, meets SIL2,SIL3 safety applications as per IEC 61508 standard. Accordingly to customer requests, it can be integrated to two way M26 manifold, or remote connection to manifold via impulse line.
