Description
The Setra 256 is a rugged industrial gauge pressure transducer built around Setra's variable-capacitance sensor, which resists shock, vibration, temperature and EMI. It covers ranges from 0–1 psi to 0–10,000 psi (0–1.6 to 0–700 bar) with ±0.13% FS accuracy on ranges of 25 psi and above.
Wetted parts are 17-4 PH stainless steel, the output is 4–20 mA or 0.1–5.1 V from an unregulated 9–30 V DC supply, and the compact die-cast aluminium NEMA 4 housing has ½ in conduit ports and zero/span adjustment.
Argonmark Ltd supplies Setra instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
