WAND TM Sensors
Thin, battery-free ultrasonic sensors which are permanently installed at thickness monitoring locations on pipework and vessels
WAND TM Sensors are permanently installed, embeddable, wireless, and ATEX Zone 0 rated. These corrosion and erosion monitoring sensors provide accurate, repeatable wall thickness measurements with RFID-enabled data traceability.
Features & Benefits
Features
Battery-Free: The WAND TM Sensors are designed to operate without the need for batteries, low-maintenance monitoring.
Intrinsically Safe: ATEX Zone 0 rated for use in hazardous environments.
Permanently Installed: Once attached to pipework or vessels, sensors deliver continuous, reliable wall thickness data over time.
Accurate and Repeatable: Measures wall thickness with high accuracy, delivering consistent results from the same location each time.
Wirelessly Activated: Simply activate the sensors wirelessly using a WAND data collector for easy, on-site data retrieval
RFID Traceability: Each sensor includes an RFID for automatic data traceability.
Applications
Embedded Monitoring: Easily installed underneath coatings and insulation, our corrosion and erosion monitoring sensors enable continuous, accurate wall thickness measurements without the need for removal or disruption of protective coatings.
Upgradable & Scalable: Designed for seamless integration with other WAND products, such as the WAND Remote Data Collector (RDC) and WAND Handheld Data Collector (HDC), allowing for scalable, networked monitoring across multiple assets or locations.
Remote Monitoring: Operators can wirelessly capture accurate, repeatable wall thickness data from fixed sensor locations, supporting continuous internal corrosion and erosion monitoring without the need for on-site inspections.
Hazardous Environments: Designed for reliability in challenging conditions such as risers, flare lines, or tank roofs, WAND TM Sensors offer a safe, non-intrusive solution for monitoring in areas with limited accessibility or increased risk.
Specifications
*Specifications are based on flat plate measurements at room temperature, may vary under operating conditions.
**For a straight pipe. The geometry affects the minimum diameter.
***Above 90˚C / 194°F, the minimum thickness that can be characterised by the sensor will increase. Please contact us for more details.
A sensor with the following specification is available on request: Minimum thickness of 2mm | Maximum thickness of up to 20mm | Maximum operating temperature of up to 110°C / 230°F
