IECEx, ATEX, SIL2 Ammonia (NH3) Gas Detector, Monitor

IECEx, ATEX, SIL2 Ammonia (NH3) Gas Detector, Monitor

DESCRIPTION

Fixed PolyXeta 2 Gas Alarm Devices of the

  • PX2-1 series with Ex db protection for Zone 1 and 2
  • PX2-2 series with Ex nA protection only for Zone 2

Designed for the continuous monitoring of the ambient air to detect combustible gases and vapors for use in the hazardous areas of zones 1 and/or 2 according to Directive 2014/34/EU.

Microprocessor-based gas sensor with 4–20 mA / RS485 Modbus output signal, alarm and fault relays (all SIL2 certified) for monitoring the ambient air to detect combustible gases and vapors by means of an infrared or catalytic sensor element (Pellistor).

The calibration of sensors without an LCD display is carried out via the calibration device STL06-PGX2 or the PC soft-ware PCE06-PGX2. Sensors with LCD display have an integrated calibration routine that is started from the outside by a permanent magnet without opening the housing. In case of an alarm or failure the backlight of sensors with LCD display changes from green to red.

FEATURES:

  •  ATEX and IEC Ex certificates MSR-Electronic for electrical Ex protection
  •  Metrological test & SIL2 safety functions 4–20 mA, RS485 and relay
  •  PX2-1 for zone 1 (and also suitable for zone 2): Type “Ex db” with flame-proof enclosure
  • PX2-2 for zone 2: Type “Ex nA” with flame-proof enclosure
  • Enclosure: additional CSA certificate for Class I, Div. 1
  • Continuous monitoring
  • Microprocessor with 12-bit converter resolution
  • Self-monitoring system
  •  Easy calibration
  • Calibration service by exchanging the sensor head
  • Proportional 4–20 mA output
  • Serial interface to the control center
  • Reverse polarity protection
  • Overload protection
  • LCD display with status LEDs (optional)
  •  Alarm and fault signal relay (optional)
