Description
The NOSHOK 623 and 624 are non-incendive pressure transmitters approved by FM and CSA for Class I Division 2 locations without the need for Zener barriers. They measure from vacuum to 15,000 psi (624 flush versions to 8,000 psi) with ±0.25% FS accuracy using a stable thin-film sensor and a welded pressure chamber with no internal seals.
Outputs are 4–20 mA or low-power 1–5 V / 0.5–4.5 V for remote sites, and the 316 stainless steel housing is NEMA 4X. The 624 has a front-flush 316 SS or Hastelloy diaphragm; both are NACE MR0175 compliant.
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.
