Intrinsically safe submersible sensors are specialized measurement devices designed for safe operation in hazardous areas classified as Zone 0, Zone 1, or Zone 2. These zones are characterized by the potential presence of flammable gases, vapors, or dust, making standard electrical equipment a potential ignition source. Intrinsically safe sensors, on the other hand, are designed to limit the electrical energy and thermal effects to a level that prevents them from causing ignition, even under fault conditions.

Applications

Oil & Gas

• Tank Level Monitoring: Accurately measure the level of crude oil, refined products, liquefied natural gas (LNG), and other hydrocarbons in storage tanks, ensuring efficient inventory management and preventing overfills or spills. These sensors can withstand harsh conditions, including extreme temperatures, high pressures, and corrosive materials.
• Offshore Platform Monitoring: Monitor levels in ballast tanks, drilling mud tanks, and other critical systems on offshore platforms, ensuring stability and preventing accidents in challenging marine environments.

Chemical Processing

• Reactor Monitoring: Measure levels, pressures, and temperatures inside reactors where volatile or flammable chemicals are being processed, ensuring safe operating conditions and preventing runaway reactions. These sensors can withstand aggressive chemicals and high temperatures, providing reliable data for process control.
• Storage Tank Monitoring: Monitor levels and temperatures of hazardous chemicals in storage tanks, preventing overfills, leaks, and potential explosions. Sensors with specialized coatings or materials can be used for highly corrosive or reactive chemicals.
• Wastewater Treatment: Monitor levels of wastewater in treatment plants, ensuring optimal conditions for biological treatment processes and preventing environmental pollution. Submersible sensors can withstand harsh conditions and provide reliable data for process optimization.

Pharmaceutical Manufacturing

• Solvent Level Monitoring: Accurately measure the level of flammable solvents used in pharmaceutical production, ensuring process control and preventing spills or leaks. These sensors must be compatible with a wide range of solvents and meet stringent hygiene standards.
• Fermentation Tank Monitoring: Monitor levels and temperatures in fermentation tanks used for biopharmaceutical production, ensuring optimal conditions for cell growth and product quality.

Landfill Monitoring

• Leachate Level Monitoring: Monitor the level of leachate (contaminated water) in collection sumps and wells, preventing overfills and ensuring proper management of this hazardous liquid. Submersible sensors can withstand the harsh environment and provide reliable data for environmental monitoring.

Selection Considerations

• Hazardous Area Classification: Determine the specific zone classification (Zone 0, 1, or 2) of your application to select the appropriate sensor.
• Measurement Parameter: Choose the sensor type that matches the parameter you need to measure (level, pressure, temperature, etc.).
• Media Compatibility: Ensure the sensor materials are compatible with the liquids or chemicals being monitored.
• Output Signal: Select a sensor with an output signal (e.g., 4-20mA, HART, Modbus) that is compatible with your control system.
• Cable Length and Material: Choose the appropriate cable length and material (e.g., PUR, PTFE) for your installation.

Intrinsically safe submersible sensors and instruments are essential for ensuring safety and efficiency in hazardous area applications. By carefully selecting and installing these devices, you can monitor critical process parameters while minimizing the risk of ignition and accidents.
