Condition Monitoring for Oil & Gas – Refineries, Petrochemicals and Hazardous Areas

Solutions for Every Hazardous-Area Zone

Hard-wired sensor loops with a Zener barrier or galvanic isolator per channel, and IRD7200 transmitters in CIMFR/PESO certified Ex-d enclosures, selected to suit the zone and gas group of each site.

Zone definitions as per IEC 60079-10-1.

ATEX, IECEx & PESO Certified Contact Sensors

Intrinsically safe accelerometers and transmitters for refinery machinery. Each sensor is chosen to suit the zone and gas group of the site.

• Loop-powered sensors for Zone 0, 1 and 2: ATEX certified, Ex ia IIC T6, 4-20 mA output.
• Intrinsically safe accelerometers for Zone 1: ATEX & IECEx Group II.
• PESO certified accelerometers for Zone 2: 100 mV/g, SS316L body, IP68; gas groups IIA/IIB.
• Intrinsically safe mini accelerometers: 100 mV/g.

For general-purpose (non-hazardous) areas: IRD521 industrial vibration sensor. See all vibration sensors.

Shaft Vibration and Gap Monitoring – IRD401

Non-contact eddy current probes for relative shaft vibration and differential expansion. We provide sensors and monitoring systems suitable for use in hazardous areas for gap monitoring: air gap, radial gap and axial gap, on DIN-rail, wall-mounted or rack-mounted monitors.

• IRD401 Non-Contact Eddy Current Proximity Sensor
• Gap monitoring via IRD8800
• Gap monitoring via IRD7100

IRD7200 in Explosion-Proof Enclosures

IRD7200 MST DIN-rail mounted within explosion-proof enclosures rated for Zone 0, 1 or 2.

Ex-d flameproof enclosures, CIMFR/PESO certified to IS/IEC 60079-1, for gas groups IIA, IIB and IIC:

• 375 × 375 × 225 mm, 2 channels: one IRD7200 with display on the lid, pre-wired for power, input and output.
• 590 × 480 × 275 mm, 12 channels: six IRD7200 and 12 displays, BNC buffered outputs, double-compression glands.

Safety Barriers and Isolators

PESO-rated sensors connect to IRD8800 M88200 modules through Zener barriers or galvanic isolators.

1. Hazardous area: PESO-rated intrinsically safe sensor.
2. Barrier: Zener safety barrier (one per channel) or galvanic isolator.
3. Safe area: IRD8800 M88200 module or IRD7200 MST.
