1. General Introduction
EJA530E gauge pressure transmitter is a simple and low cost in-line direct mount type for measurement of gauge pressure, maximum measure range up to 500bar; turndown ratio is 20:1 for capsule range A, B, C and 10:1 for capsule range D; stability under normal working condition is ±0.1% for 7 years.
For wetted material, SUS316L and hastelloy C 276 selectable, which is suitable for almost all most working cases, wetted parts consist of process connector, diaphragm capsule and internal parts. During material selection, material code S is for non-corrosive fluid working conditions by which SS316 process connector and other wetted part material will be selected; material code H is for corrosive fluid working conditions by which hastelloy C276 process connector and other wetted part material will be selected. for Non-wetted Parts Materials, Housing is Low copper cast aluminum alloy with polyurethane, deep sea moss green paint (Munsell 0.6GY3.1/2.0 or its equivalent), or ASTM CF-8M Stainless Steel.
For Transmitter mounting, it can be mounted directly to manifold by thread, thread connection is capable to hold the transmitter weight which is around 1.5kgs; additionally, transmitter can also be mounted by a horizontal 2-inch pipe, SS316 mounting bracket is optional to be selected as suffix code /L.
For connection to manifolds, two types of manifold connections are optional, For integrated type, it's available to integrated directly to a CV1G cylindrical manifold with connection 1/2NPTM, 1/2NPTF, G1/2 or M20*1.5; for remote type, it can also follow traditional type with pulse lines. For selecting wetted material type of transmitter; complete same type wetted material type of manifolds can also be selected.
