Description
The whole range of hot-swappable smart modules (electrochemical, catalytic, infrared and MEMS) fits one transmitter, the module is recognised automatically and the range is selected on site, which reduces the time instrument staff spend in the hazardous area. Gas type, scale and calibration data are stored in the module itself, so it is calibrated on a bench in a safe area and replaced in seconds without a hot work permit. The sensor can be mounted separately from the transmitter so that the point can be serviced from a safe place. The 128×64 pixel OLED display can be read even in the dark, amber, red and green LEDs show the status, and the blue +Ve Safety indicator confirms healthy operation at a glance. Cables enter through three M20 or 1/2″ NPT entries.
How to choose
The module is chosen by gas and scale. Ranges of 0–50, 0–100 and 0–1000 ppm are available for ammonia, 0–250, 0–500 and 0–1000 ppm for carbon monoxide, 0–5, 0–10 and 0–20 ppm for chlorine, 0–25 ppm for hydrogen cyanide and 0–10 ppm for hydrogen fluoride, and there is also a high-temperature H2S sensor. The full scale can be set to the requirements of a specific point, and where FM approval is needed, the modules for methane, propane or H2S HT are used. For hydrocarbons in zones 1 and 2 with IR measurement, the IRmax with consumption below 1 W is suitable.

FAQ
What outputs does XgardIQ have for connection to the process control system?
A 4–20 mA current output with sink/source auto-detection and warning and fault signals per NAMUR NE 43, digital RS-485 Modbus RTU, and optionally HART 7 over the current loop with intrinsically safe test points.
What are the parameters of the optional XgardIQ relays?
The Alarm 1, Alarm 2 and Fault relays have 5 A 230 V AC contacts. They are configured as normally energised or de-energised, latching or non-latching, on rising or falling concentration.
Does XgardIQ have SIL certification?
Yes, the detector is certified to SIL2 and for its measurement performance, so it can be included in emergency shutdown loops.
What are the power supply and consumption of XgardIQ?
The detector is powered by 14–30 V DC and consumes less than 4 W.
