Toxic and oxygen gas detector TXgard+
- Calibration can be performed locally without the need for hot work permits
- Local display and magnetic key enable calibration without opening the junction box
- 4...20mA signal is provided
- Optional alarm and fault relays are available
TXgard-Plus is a flameproof toxic and oxygen gas detector suitable for use in zone 1 or 2 hazardous areas. It is designed to detect toxic gases and oxygen using a range of electrochemical sensors.
A local display and magnetically operated switches allow non-intrusive one-man calibration without a hot work permit.
Powered by 24 VDC (nominally) TXgard Plus provides a 4...20 mA signal (sink or source) proportional to the gas concentration and can also be fitted with optional alarm and fault relays.
