Performance Specifications (General for 266DSH) Base accuracy: from ±0.06% of calibrated span (depending on sensor/span configuration) Span limits (differential pressure span options): from as low as 0.05 kPa up to 16,000 kPa depending on sensor option — wide flexibility. Turn-down ratio: up to 100:1 (depending on configuration) Static (line) pressure capability: depending on sensor and static-pressure rating; typical static pressure ratings up to tens of MPa for standard static versions — able to withstand high line pressures even while measuring small differential pressures. Over-/Proof pressure capability: Designed to handle high static pressures safely; in standard static versions the transmitter can be exposed to high overpressure without leaking (static pressure rating varies with sensor / materials). Output / Communication Options: Standard 4–20 mA + HART digital communication. Other fieldbus/digital protocols (e.g. FOUNDATION Fieldbus, PROFIBUS PA) are available depending on ordering code. Configuration & Display: Configuration can be done locally via integrated LCD + keypad (TTG) or via external HART / fieldbus communicator or PC. Diagnostics & Safety: Built-in diagnostics including Plugged-Impulse-Line Detection (PILD). Suitable for SIL2 / SIL3 safety-critical applications. Environmental / Robustness: Suitable for harsh process / ambient conditions; designed for industrial environments with vibration, variable temperature, possibly dusty or wet atmospheres; meets relevant industrial standards for electromagnetic compatibility, ingress protection (dust/water), shock & vibration, static-pressure endurance, etc. Units / Output Scaling: Supports wide range of engineering units for pressure differential (kPa, Pa, MPa, bar, psi, inH₂O, ftH₂O, mmHg, atm, etc.) depending on configuration and communication protocol. Flexible Configuration: The transmitter is factory-calibrated to customer-specified span / range; but all parameters (Lower Range Limit, Upper Range Limit, engineering units, damping, tag name, static pressure rating, flange type/material, O-rings, vent/drain valve, optional display, certificates etc.) can be configured later via communicator or PC.
