Description
The APG PT-400 is a heavy-duty pressure transducer for high-vibration, high-shock and hazardous locations, covering vacuum up to 30,000 psi (about 2,070 bar) with ±0.25% FS accuracy. Laser-welded construction, fully potted electronics and IEC 61000-4-5 surge protection make it suitable for drilling rigs, fracking units, large pumps and engines.
Outputs include 4–20 mA, several voltage ranges and RS-485 Modbus. Wetted parts are 316L or 17-4 stainless steel, or Incoloy (NACE MR0175) for the highest pressures. The 4–20 mA version is intrinsically safe for Class I Div 1 / Zone 0 with CSA, ATEX and IECEx approvals up to 10,000 psi.
Argonmark Ltd supplies APG 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.
