Hydrostatic Sensing for Constrained Installations
Pressure EX is a hydrostatic pressure-based level sensor for installations where radar or ultrasonic sensing is not viable — and where safety regulations require ATEX/IECEx certified hardware. It measures tank levels using a submersible probe, independent of tank geometry, line-of-sight, or internal obstructions. Certified for use in Zone 0 explosive atmospheres (SGS22ATEX0060X / IECEx BAS 22.0034X / II 1 G Ex ia IIC T4 Ga), it enables monitoring in environments where standard sensors are not permitted.
Core Capabilities
- ATEX Zone 0 and IECEx certified — approved for the most hazardous liquid storage environments where standard sensors cannot be deployed
- Dual-certified system: logger and probe both carry Zone 0 / Ex ia IIC approval for fully compliant installations
- Hydrostatic probe measurement independent of tank geometry, obstructions, or line-of-sight
- 5 m probe cable reaches deep tanks with constrained or angled openings
- Integrated data logger protects data continuity on signal loss
Where Pressure EX Fits
- Tanks with long or angled openings
- Tanks with internal cross bracing
- Geometry obstructing line-of-sight measurement
- Installations requiring probe-based sensing
- Zone 0 explosive atmosphere installations requiring ATEX/IECEx certified hardware (SGS22ATEX0060X / IECEx BAS 22.0034X / II 1 G Ex ia IIC T4 Ga)
Industry applications: Heating Oil · Diesel
Ideal Use Cases
- Heating oil and diesel tanks in Zone 0 explosive atmospheres
- Tanks with constrained geometry, angled openings, or no viable radar line-of-sight
- Installations requiring full ATEX/IECEx dual-certification for both logger and probe
- Operations requiring complete tank coverage regardless of geometry or hazard classification
Deployment Requirements
- Requires a G1″ or G2″ threaded connection for probe insertion
- Connectivity: LTE NB-IoT and LTE CAT-M1 only
When to Use a Different Sensor
Pressure EX is a specialised device for certified and constrained environments. Consider an alternative when:
- The installation does not require ATEX/IECEx certified hardware (→ use FoxPressure Gen 4)
- Radar measurement is stable and feasible for the tank geometry (→ use FoxRadar Gen 4)
- Simpler installation is preferred and the environment is not hazardous
Role Within the FoxInsights System
Pressure EX provides level time-series input to the platform layer for forecasting. Monitoring is sensing; forecasting remains platform-layer.
Integrated with FoxPortal
- Level data from Zone 0 installations transmitted to FoxPortal for full portfolio coverage
- Consumption-based forecasting without monitoring gaps in the most demanding environments
- Structured refill planning across all tank types including hazardous installations
