Its sensor span covers 0.54 to 16 kPa (5.4 to 160 mbar, 2.16 to 64 inH2O), making it suited for low-to-moderate DP applications like filter monitoring, flow measurement across orifice plates, or level measurement on closed tanks. The output stage is HART digital communication superimposed on a 4 to 20 mA analog signal, standard functionality — no special protocol stack or custom linearization ordered here. ## Wetted materials and environment The diaphragm is Hastelloy C-276 with silicone oil fill, and the bolts/gasket are AISI 316 SS with PTFE — all NACE compliant, so this build is ready for sour-gas or corrosive process streams without a material upgrade. Housing is AISI 316L stainless steel in the barrel version, with a 1/2 in – 14 NPT electrical connection. That barrel form factor is compact for close-pipe mounting; the 316L shell stands up to washdown and coastal atmospheres. Process flanges are AISI 316L SS with horizontal connection via 1/2 in – 14 NPT-f through adapter, also NACE rated. The horizontal port orientation simplifies impulse-line routing on vertical pipe runs. Estimated lead time is 6 to 8 weeks from order placement.","metaTitle":"266DSHESKB4S7E7LSB2M5I2C1H1 266DSH DP Transmitter, 0.54-16 k","metaDescription":"266DSHESKB4S7E7LSB2M5I2C1H1 differential pressure transmitter, 0.54-16 kPa span, HART 4-20 mA output, Hastelloy C-276 diaphragm, AISI 316L SS housing.
