Flamgard Plus is a Flameproof (Ex d), ATEX, IECEx and UL certified flammable gas detector with LCD display and non-intrusive calibration. Uses a poison resistant pellistor sensor located in a 316 stainless steel flameproof housing. Complete with a marine-grade alloy junction box which contains an amplifier/transmitter to provide a 3-wire 4-20mA output.

A 3-digit LCD display with backlight and LED status indicator provide a user-interface, and calibration is performed using a magnetic wand (supplied). The junction box is available with M20, 1/2″ or 3/4″ NPT cable entries. Operating temperature –10 to +55ºC.

Features

Non-intrusive calibration

  • Calibration can be performed locally without the need for hot work permits – minimises operational down-time.
  • Local display and buttons enable calibration without opening the junction box

Flexible output options

  • 4-20mA current sink or source – works with a wide selection of control panels
  • Three-wire format
  • Optional relays for alarm and fault – can be used for switching local alarms

Rugged and reliableflamgard_plus_prod_img_3

  • Constructed using marine-grade aluminium with a stainless steel sensor housing – proven track record for operation in the harshest environments
  • Ingress protection to IP65 as standard

Low cost of ownership

  • Non-intrusive one-person calibration – easy to operate and maintain
  • Long-life sensors – keep interruption to on-site activity to a minimum
  • Simple parts replacement

Sensors

  • Choice of catalytic beads to detect explosive levels of hydrocarbons, hydrogen and other flammable gases and vapours, including aviation fuel and leaded petrol vapours
