Parameters Category Parameter Specification / Interpretation for 266DSHBSHA1B2 V1L1B1TB General Model Series 2600T Series (DST - Differential Pressure Smart Transmitter) Type Smart dP Transmitter with Steam Flow Option & Local Display Output 4-20 mA DC, Two-wire, HART Protocol. Measurement & Computation Primary Measurement Differential Pressure (dP) Calibrated dP Span (BSHA1) Defined by core code. Example: 0 to 100 kPa (1 bar). Must verify from datasheet. Reference Accuracy (dP) ±0.075% of calibrated span (Typical). Steam Flow Option (V1) On-board IAPWS-IF97 steam properties. Output can be configured as Mass Flow Rate (e.g., kg/h, lb/h). Output Characterization (B1) Selectable: Linear (for pressure/level) or Square Root (for flow with primary element). With V1, output is linearized flow. Options & Features Local Display (L1) LCD Local Indicator. Certification Package (TB) ATEX / IECEx: Ex d IIC T4/T6 Gb (Flameproof) & Ex ia IIC T4/T6 Ga (Intrinsic Safety) certificates. Electrical Supply Voltage 10.5 to 45 V DC (Two-wire). Communication HART Protocol. Process Connections & Materials Wetted Parts (BSH) Isolating Diaphragms: 316L SST or similar alloy.
