Product Details
1. General Introduction
EJA120E differential pressure transmitter is a high performance draft range type specially for very low range differential pressure measurement, it specially for 0-1kpa applications. It supports 5 types of output signals. For output signal -D, it's based on brain protocol with 4 to 20 mA DC with digital communication; for output signal -J, it's based on Hart protocol with 4 to 20 mA DC with digital communication based on Hart 5/Hart7, Hart 7 is a low power consumption type which can be ordered for power economical plants application which need to specify during order stage; otherwise deem to Hart 7 automatically; for output signal -F, it's based on FOUNDATION Fieldbus protocol Digital communication; for output signal -G, it's based on PROFIBUS PA protocol Digital communication; for for output signal -Q, it's based on Hart 7 low power digital communication based on 1 to 5 V DC.
