Below is a small selection of the accessories available for the TXgard Plus.
For use outdoor installations and to protect from water sprays, for example in water treatment or food processing plants. For extremely wet environments eg: offshore installations, use weatherproof cap, CO1442, instead.
For offshore or other extremely wet environments in place of spray deflector.
Stainless steel flow adaptor
For use where a gas sample is being piped to the detector.
Exd Cable Gland Adaptors
ATEX certified Exd cable gland adaptors.
Exd/Exe Certified Brass Cable gland
Suitable for Steel Wire Armoured cables with outside diameter 15.5mm to 21.1mm (inner sheath 6.7mm to 14mm). Certified to ATEX (ll 2DG, Exd llC/Exe ll), IECEx, CSA, GOST-R and NEPSI standards. M20 x 1.5mm thread. Ingress protection to IP66/67/68.
To enable calibration gas to be applied to the detector. One adaptor can be used for several detectors.
