⚠️ Load resistance: 250–1,345 Ω for SFN/DE communication; 250–600 Ω for HART. A minimum of 250 Ω is required for communicator use. Intrinsic safety types limited to 12.5–30 V DC supply.
💡 Why the GTX stands out: The 200:1 turndown ratio means a single model covers applications from near-vacuum to high pressure — reducing the number of spare parts you need to stock. The ±0.1% URL / 10-year stability rating eliminates routine calibration downtime, which Azbil claims is the best in the industry for this class of transmitter.
