XgardIQ

Intelligent and versatile gas detector and transmitter.

Overview

Overview

XgardIQ is an intelligent and versatile gas detector and transmitter compatible with Crowcon's full range of sensor technologies. Available fitted with a variety of flammable, toxic or oxygen gas sensors.

Providing analogue 4-20mA and RS-485 Modbus signals as standard, XgardIQ is optionally available with Alarm and Fault relays and HART communications. The 316 stainless steel are available with three M20 or 1/2"NPT cable entries.

Easy and safe to use

  • OLED displayBright, clear display indicates gas level and detector status even in dark locations
  • Non-intrusive calibrationZero and calibration functions are performed via the display and keypad, without the need for a hot-work permit or any special tools (e.g. no magnetic wand required)
  • +ve Safety indicatorConfirms the detector is operating safely at a glance
  • Event log functionStores all alarm, fault and maintenance events to provide a history of detector use

Simple installation and maintenance

  • Universal transmitter - Common transmitter for Crowcon's full range of sensor technologies
  • Hot-swap sensor modules - Sensors can easily be replaced using one hand without requiring tools or a hot-work permit
  • Auto-sense function - Automatically detects whether the control system is 4-20mA current sink or source and sets itself appropriately, eliminating the risk of being incorrectly set
  • Auto-configure function - Detects when a sensor module is plugged-in and uploads the appropriate gas type, range, units and alarm levels

Reliability

  • Smart Bump and Speedy Bump test functions - Enable sensor health and response to be verified quickly and easily using test gas. Process is automated and provides a reminder when a bump test is due
  • Calibration due warning - Reminds the user when calibration is due to ensure that sensors remain operational and accurate at all times
  • Sensor range selection - User can set the full-scale range of the sensor via the display menu according to site or specific location requirements
