Description
TXgard-IS+ is an Intrinsically Safe detector for toxic gases or oxygen.
It is suitable for use in Zone 0, 1 or 2, or Division 1 / Division 2 hazardous areas when used with a suitable Zener barrier or galvanic isolator. TXgard-IS+ is designed to detect a wide range of gases when fitted with the appropriate electrochemical sensor.
TXgard-IS+ is a loop-powered instrument providing a 4-20 mA signal suitable for direct connection to a control panel. Unlike most other 4-20 mA gas detectors featuring operator display panel (LCD) and keypads, it combines its power and signal in just two wires, so only one barrier is required.
