Description
The NOSHOK 625 and 626 are intrinsically safe pressure transmitters, FM and CSA approved for Class I, II and III Division 1 and Class I Zone 0 with approved barriers. They cover very low ranges from a few oz/in² up to 15,000 psi, with ±0.25% FS accuracy (±0.125% optional) and ≤ 0.2% FS drift per year.
The 625 has a welded 316 stainless steel chamber with no internal seals, and the 626 a front-flush 316 SS or Hastelloy C4 diaphragm. They give a two-wire 4–20 mA output with ±10% zero and span adjustment and a wide choice of electrical connections.
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.
