The Drager PIR 7000 gas detector continuously monitors flammable gases and vapours. It uses point infrared technology and is explosion-proof. Built to withstand harsh industrial environments, such as offshore installations, it has a hermetically sealed stainless steel 316L enclosure with drift-free optics.
The optical 4-beam technology ensures the utmost signal stability for all models over long periods. The gas transmitter is available with an M25 or a 3/4-inch NPT thread.
There are two versions:
- The type 334 model provides comparable sensitivity in the Lower Explosion Limit (LEL) measuring range for many gases and vapours containing hydrocarbons such as methane, propane, and ethylene.
- Type 340 model offers high sensitivity for propane and alkanes of greater length, such as octane and nonane. This allows for more sensitive measurements and alarm thresholds in the ppm range. Methane and ethylene are more weakly detectable with this model.
Features
- Configurable gas library – methane, propane and ethylene fixed. Up to 10 additional substances can be uploaded
- Beam block warning in case of dirty optics for preventive maintenance
- Long maintenance intervals
- Multiple mounting and configuration capabilities (signals acc. to NAMUR NE 43)
- Extended temperature range of up to + 77 °C / + 170 °F
- Double-compensating, non-imaging optics (using 4-beam technology)
- Single cable multidrop capability using HART communication
- Conventional 4-to-20-mA analogue signal output
- Approvals ATEX, IECEx, UL, CSA
- SIL 2 certified
- Dust approval for zones 21 and 22
- Integrated tag holder for individual labelling
- Resistant towards shock and vibration up to 4 G
- Continuously self-tests – IEC/EN 61508 standard
- Size: length 160 mm, diameter 89 mm, weight 2.2 kg (excluding accessories)
