OVEN PD100I sensors model 111/171/181-Exi are made in accordance with the requirements of GOST R IEC 60079 for explosion-proof electrical equipment of group II and are pressure transducers with a measuring membrane made of AISI 316L stainless steel, a sensor based on CNK technology and a cable gland according to EN175301- 803 (DIN43650 A).

These models are characterized by increased measurement accuracy (from ±0.25% URL), resistance to water hammer and relatively low output noise (no more than ±16 μA).

The converters of these models are designed for use in gas distribution and gas control cabinets, panels and points (GRP, GRPSH, MSB) of automatic control systems of gas supply enterprises and gas networks, in boiler automation and in categorized “dangerous” industries.

Key Features of the Explosion-Proof Converter

  • measurement of excess/absolute/vacuummetric/gauge-vacuum pressure of explosive media neutral to stainless steel AISI 316L (AISI 304S) (natural gas, combustible liquids and their vapors).
  • explosion protection type “intrinsically safe circuit” 1ExiaIICT6Gb.
  • basic reduced error – 0.25; 0.5% URL.
  • conversion of pressure into a unified DC signal 4…20 mA.
  • the upper limit of the measured pressure (URL) – from 10 kPa to 4.0 MPa.
  • overload capacity – not less than 200% VPI.
  • degree of protection of the body and electrical connector of the converter – IP65.
  • noise immunity meet the requirements for class A equipment according to GOST30804.6.2-2013.
