Crowcon IRmax with Fixed IR Display | IR Gas Detector, Local Display | T90 <4 s, <1 W, 230x75x57mm
This IRmax configuration adds a fixed local gas and status display to the infrared hydrocarbon detector, giving an overall size of 230 x 75 x 57 mm and a weight of 2 kg. Readings can be checked at the detector itself while keeping the under 1 W consumption and Stay-ClIR condensation-proof optics. It is certified Exd ia IIC T4 Gb.
Key features
- Stay-ClIR coated optics prevent condensation faults
- Under 1 W power, so small supplies and battery back-up suffice
- Wall, 50 mm pipe or junction box mounting
- 2 mA dirty-optics warning and 0 mA fault signal
- Annual proof-test interval; SIL 2 validated
