Crowcon Flamgard Plus Gas Detector
The Crowcon Flamgard Plus is a flameproof (Ex d) gas detector that uses poison-resistant pellistors to detect explosive levels of hydrocarbons, hydrogen and other flammable gases and vapours, including aviation fuel and leaded petrol vapours.
Crowcon Flamgard Plus has a wide selection of sensors including a number of catalytic beads for a wide selection of flammable gases and vapours as well as electrochemical sensors for toxic gases and oxygen.
The Crowcon Flamgard Plus gas detector is easy to calibrate. Maintenance and operation are simple and the long life sensors keep disruption to site to a minimum.
Crowcon Flamgard Plus has an ingress protection to IP65 as a standard.
Crowcon Flamgard Plus Fixed Gas Detector – Key Features
- Robust Construction – Crowcon Flamgard Plus is constructed using marine grade aluminium with a stainless steel sensor housing
- Flexible Options – The Flamgard Plus is available in 2 or 3 wire formats with a 40-20mA current sink or source. Relays for alarm and fault are also options
- Low Ownership Costs – Sensors are long life with simple part replacement making the gas detector easy to operate and maintain
- Calibration – The Flamgard Plus can be calibrated with ease and boasts local display and buttons so the junction box doesn’t need to be opened. Non-intrusive one man calibration can be performed locally without the need for hot work permits
- Range of Sensors – This gas detector can be tailored to meet the user’s needs with a choice of catalytic beads for a wide selection of flammable gases and vapours and an extensive range of electrochemical sensors for toxic gases and oxygen
Crowcon Flamgard Plus Bump Testing And Calibration
Routine bump testing is recommended for the range of Crowcon fixed gas detectors prior to each use. Bump testing is a brief application of a gas to the sensor to invoke a prescribed reaction, ensuring the gas detector reacts as expected.
Bump testing provides a quick, easy and direct method of verifying gas detectors are performing as required and takes a lot less time than ‘zeroing’ the device.
The bump test is widely accepted as a suitable method of testing gas detection equipment.
