The 266HRHSRRB1E1E2L1B7H1+S26RAHE5SFSM1AESNNN is a gauge pressure transmitter with a remote seal and an S26RA rotating flange diaphragm seal assembly (flush diaphragm, AISI 316L SS). The kit includes the transmitter with an integral digital LCD display, a 3 m (10 ft) AISI 316L SS armoured capillary, a pipe/wall mounting bracket in AISI 316L SS, and an aluminium alloy barrel housing with M20 x 1.5 electrical connection. The flange is ASME CL 900-1500, 2 in., with serrated surface finish. No flushing ring is fitted. Material traceability per EN 10204-2.1 is included for process wetted parts.
Span limits are 267 to 16000 kPa (2.67 to 160 bar, 38.7 to 2320 psi) — covers most process pressure ranges in chemical, petrochemical, and oil & gas applications. The HART digital communication and 4-20 mA output means it integrates directly with any HART-compatible DCS, PLC, or handheld configurator; no separate protocol converter needed. ATEX certification Ex d IIC T6 and Ex tD A21 IP67 T85 °C qualifies it for Zone 1/2 gas and Zone 21/22 dust hazardous areas — the flameproof enclosure and IP67 seal let it mount directly on the vessel or pipe in a classified area without an additional purge system.
Deployment context
The aluminium barrel housing and M20 x 1.5 conduit entry suit direct pipe or wall mounting via the included AISI 316L SS bracket. The 3 m capillary gives flexibility to locate the transmitter away from the process connection — useful where vibration or temperature at the tap exceeds the transmitter's limits. The IP67 rating on the ATEX dust certification confirms the housing withstands washdown and outdoor exposure.
