XgardIQ (Please call for price)
Overview
XgardIQ is an intelligent and versatile fixed detector and transmitter compatible with Crowcon’s full range of sensor technologies. Available fitted with a variety of sensors for fixed flammable, toxic, oxygen or H2S gas detection.
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.
(SIL-2) Safety integrity level 2 certified fixed detector.
Easy and safe to use
- OLED Display – Bright, clear display indicates gas level and detector status even in dark locations
- Non-Intrusive Calibration – Zero 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 Indicator – Confirms the detector is operating safely at a glance
- Event Log Function – Stores all alarm, fault and maintenance events to provide a history of detector use
- Remote Sensor – Improves probability of detection
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.
