The 266HSHWKTB1 is a gauge pressure transmitter from the 266HSH series, built for process pressure measurement in industrial lines. It covers a span of 1400 to 70000 kPa (14 to 700 bar, 203 to 10150 psi), so it handles medium-to-high pressure ranges typical in oil and gas, chemical, and water treatment applications. The output is 4-20 mA with HART protocol, advanced functionality — that means you get digital communication over the analog loop for remote configuration, diagnostics, and multi-variable reads without pulling extra wires.
Wetted parts and material selection
The diaphragm is Hastelloy C-276 with silicone oil fill. The process connection is AISI 316L SS, 1/2-14 NPT male, NACE compliant for sour service. Housing is aluminium alloy, barrel version, with an M20 x 1.5 electrical connection — the barrel form factor is compact for tight pipe-stand or manifold mounting, and the M20 gland accepts standard cable entries.
