It delivers a HART and 4 to 20 mA advanced-functionality output, making it suitable for continuous process monitoring where remote seal isolation is required — common in viscous, corrosive, or slurry applications where direct impulse lines would clog or corrode. The transmitter's sensor span covers 2.67 to 160 kPa (10.7 to 642 in. H2O) with a base accuracy of 0.075%, which means it resolves small pressure differentials across filters, heat exchangers, or level measurements in closed tanks. The integral LCD display with keypad (L1 option) allows on-site configuration and readout without a handheld communicator — a practical advantage during commissioning or loop checks. ## Wetted parts and fill fluid All wetted surfaces — diaphragm, mounting flange, and process adapters — are AISI 316L stainless steel, with the diaphragm material specified as AISI 316L SS and fill fluid as silicone oil PMX 200 10 cSt. The capillary is 3 m (10 ft) long with AISI 316L SS armour (A option), protecting the fill line from mechanical damage in field installations. The seal surface finish is serrated (1 option), which improves gasket grip on the mating flange. ## Hazardous area and compliance documentation ATEX Explosion Proof Ex d certified. Housing is AISI 316L SS barrel version with M20 x 1.5 electrical connection. Ships with inspection certificate EN 10204 3.1 of calibration (9-point) and material traceability per EN 10204-2.2. The mounting flange is ASME CL 150 / 2 in. (option), a standard ANSI pattern that mates directly to process piping without adapters. The mounting bracket is AISI 316L SS for pipe mounting (B2 option), suitable for 2-inch vertical or horizontal pipe stands. The low-pressure side connection is clearly marked (L option), and the bolts are AISI 316 SS with no gaskets for the two-seal construction, rated to a maximum working pressure of 16 MPa / 160 bar / 2320 psi.","metaTitle":"266DRHHSRRRT1-E2L1B2I2N5C1H4 + S26RAHE1SFSM1AESNNN + S26RALE","metaDescription":"Differential pressure transmitter with rotating flange diaphragm seals.
