Description
The NOSHOK 627 Series is an intrinsically safe submersible level transmitter approved by FM and CSA for Class I, II and III Div 1 and Class I Zone 0 hazardous locations. Its pressure chamber is welded 316 stainless steel with no internal O-rings, gaskets or seals, and its thin-film sensor gives ±0.25% FS accuracy (±0.125% optional) with ≤ 0.2% FS drift per year.
Ranges run from 0–50 inH2O (about 1.3 m of water) up to several hundred psig. It is a two-wire 4–20 mA device powered at 10–30 V DC, rated IP68 for continuous submersion, and available with a nosecone, weighted nosecone or NPT adapter.
Argonmark Ltd supplies NOSHOK 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.
