Description
The Crowcon XgardIQ is an intelligent, versatile fixed gas detector and transmitter in a 316 stainless steel enclosure, with a bright OLED display and a +Ve Safety indicator that shows at a glance — and from a distance — that the detector is operating soundly. It is a universal transmitter: plug in the XgardIQ sensor module for the gas you need, and the auto-configure function uploads the correct gas type, range, units and alarm levels, while auto-sense detects whether your control system is a 4-20mA current sink or source.
The transmitters listed here are supplied with NO sensor module fitted (the ZZ in the part number) — choose the module for your gas from the Crowcon XgardIQ Sensor Modules product, linked below. Modules hot-swap in seconds with the tool provided, with no hot-work permit, so a pre-calibrated spare keeps the point protected while the removed module is calibrated in a safe area. Configurations listed here are English-display builds with ATEX/IECEx, INMETRO or no hazardous-area certification, exactly as stated in each configuration — Crowcon does not offer this transmitter in a UL/CSA configuration in the current range.
How to read the configuration code: XIQ-ZZ = transmitter with no sensor module fitted; S1 = M20 cable entry, S2 = 1/2" NPT (316 stainless steel either way); 000 = no hazardous-area certification, 011 = ATEX/IECEx, 012 = INMETRO; H = HART fitted, R = alarm & fault relay outputs fitted; final A = English display. Every configuration in the dropdown also spells out its entry, certification and options in full.
You also need a sensor module: this transmitter is supplied with no module fitted. Order the module for your gas from the Crowcon XgardIQ Sensor Modules — pellistor, electrochemical and infrared modules cover flammable gases, toxic gases and oxygen.
Common Applications:
Oil & Gas • Petrochemical • Chemical Plants • Water & Wastewater • Steel • Power Generation • Marine & Offshore
