Non-Invasive Thickness & Corrosion Monitoring
We are the extreme environment experts. We enable plant digitalisation and the realisation of Industrial IOT solutions. We combine our market leading HotSense™ sensors with the best-fit data collection system to provide a complete monitoring solution to deliver key asset integrity data, meeting cost, HSE, and operational targets across refining, oil & gas, energy, nuclear and process sectors
Start monitoring your assets with HotSense™ to increase plant productivity:
- Remove variables caused by periodic inspection process.
- Provide more frequent data, with no increase in costs to improve RBI data / deliverable.
- Get more actuate data to feed your FFS studies.
- Remove conservatism from your asset retirement planning.
- Enable use of lower cost feedstock options
- Confirm effectiveness of corrosion inhibitors.
- Enable better data to make informed decisions around change management:
- Production increases
- Shutdown planning
ADVANTAGES

OPTIMISED
- Increase what can be monitored – HotSense™ transducers allow for deployment directly to hot assets for measurements from -55 to + 550˚C (-67 to 1022 ˚F).
- Increase Safety – Intrinsically safe and certified for deployment across your business (FM Cl 1 Dv 1-2, ATEX & IECEx Zone 0-1)
- Reduced maintenance – Transducers and node may be positioned independently to allow for ease of access for battery change – no need for scaffolding or rope access. Service packages available.
- Cost efficient – Multiple transducers per measurement node to minimise batteries.
- Improved network stability – Nodes positioned to maximise wireless signal.
- Maximise flexibility – Flexible and robust deployment and data management options
AUTOMATED
- Automated – thickness measurements, temperature measurements and corrosion rates transmitted directly to your control room.
- Security – Advanced data management software on local server or data direct to you DCS and PIMS – data never leaves your site.
- Configurable alarms – Robust and reliable measurements for determination of wall loss rates & absolute thickness.
- Inhouse data access – Make data available to both maintenance and operations teams to better optimise plant productivity.
- Built-in calibration – Measurements may be validated using HotSenseTM transducer integrated calibration block.
WIRELESS
- Fully WirelessHART certified and compliant for integration into your operations.
- Remote measurement configuration and maintenance.
- Battery life is transmitted allowing maintenance and data collection scheduling.
CASE STUDIES

Online Wall Thickness Monitoring
Refinery wide HotSense™deployment to reduce risk, increase safety and maximise data availability.

Realtime, Remote Erosion Monitoring of Shell Wellheads
Upstream HotSense™
deployment with cellular data transfer to:
• Maximise production, based on known erosion rates
• Increase safety, reduced site activity & personnel exposure
to X-ray
• Reduced costs by automating data collection remotely
