The 266HRHPRRB1E1L1B7H1+S26RAHE2SFSM1AESNNN is a gauge pressure transmitter with a remote seal and an S26RA rotating flange diaphragm seal assembly — flush and extended configurations. It carries a digital LCD integral display (L1), HART digital communication over a 4 to 20 mA loop, and ATEX Intrinsic Safety certification for hazardous-area deployment. Span limits cover 40 to 2400 kPa (0.4 to 24 bar, 5.8 to 348 psi), and the mounting flange is ASME CL300 / 2 in.. The fill fluid is silicone oil DC200 10 cSt, and the diaphragm material is AISI 316 L stainless steel.
The transmitter body is housed in an aluminium alloy barrel with an M20 x 1.5 electrical connection (CM 20). The mounting bracket (B7) is AISI 316 L stainless steel for pipe or wall mounting. The remote seal assembly uses a 3-metre (10-foot) capillary with AISI 316 L stainless steel armour. The flushing ring option is omitted (N = None) on this configuration. The seal surface finish is serrated. Material traceability is provided via a certificate of compliance with EN 10204–2.1 for process wetted parts.
