Industry 01

Oil & Gas Sensor Applications — Level, Pressure & Flow Solutions

Sensor Challenges in Oil & Gas Operations

Oil and gas facilities demand sensors that perform reliably in explosive atmospheres, extreme temperatures, and highly corrosive media. Tank farms, separator vessels, pipelines, and wellheads all require continuous, certified measurement — where sensor failure directly affects safety and production.

SEGMENsensor ATEX & IECEx Solutions

SEGMENsensor offers ATEX/IECEx explosion-protected versions as an option on selected models for Zone 1 and Zone 2 hazardous area classifications. For hazardous tank farms, the SE-LX10 / SE-LX20 / SE-LX30 magnetostrictive level transmitters have a flameproof housing, with a high-temperature rod version rated -40 to +250 °C. Clamp-on ultrasonic flow meters enable non-invasive flow measurement on existing pipelines without process shutdown; they are not explosion-protected, so they are installed outside hazardous zones.

Food & Beverage Sensor Applications — Hygienic 316L Options

Hygienic Sensor Requirements for Food Production

Food and beverage production demands sensors that withstand CIP (clean-in-place) and SIP (sterilize-in-place) cycles, resist aggressive cleaning agents, and use only food-grade wetted materials. Level measurement in ingredient tanks, flow monitoring for filling lines, and proximity detection for conveyor control are the three highest-volume applications.

CIP-Compatible Sensors from SEGMENsensor

SEGMENsensor float-type level sensors are available with 316L stainless steel and PVDF-coated components for food-compatible media.

Chemical & Petrochemical Sensor Applications — Corrosion-Resistant Sensors

Corrosive Media & Hazardous Area Requirements

Chemical plants present some of the most demanding sensor environments: highly corrosive acids and alkalis, elevated operating temperatures, pressurized vessels, and in many cases hazardous area classifications. Sensors must survive continuous exposure to aggressive media without material degradation or signal drift.

PVDF, Hastelloy & ATEX-Rated Sensor Options

SEGMENsensor magnetostrictive level sensors with PVDF or Hastelloy wetted components are the preferred solution for chemical tanks — delivering high repeatability (±0.005 mm, SGM-LS10; PP / PFA on SGM-LC10) with no electronics in the medium. Pressure transmitters with ceramic or PTFE diaphragms handle aggressive process media at up to 400 bar. ATEX/IECEx versions are available as an option for Zone 1 and Zone 2 areas.

Energy Storage & Battery (BESS) Sensor Applications — Coolant Level, Leak & Temperature

Liquid-Cooled Battery & Thermal Management Sensing

Battery energy storage systems (BESS) and grid-scale storage increasingly use liquid cooling — cold plates, coolant distribution units (CDUs), and immersion tanks — to keep cells within a safe temperature window. These loops need accurate coolant level, coolant temperature, leak detection, and pump-loop pressure monitoring to protect high-value battery racks and satisfy fire-safety requirements.

Level, Temperature & Pressure for Storage Systems

Common Questions

Frequently Asked Questions About Industrial Sensor Applications

What sensors are used in oil and gas pipelines?

Oil and gas pipelines typically require explosion-protected level sensors for storage tanks, pressure transmitters for line pressure monitoring, ultrasonic flow meters for non-invasive flow measurement, and magnetostrictive position sensors for valve and actuator feedback. SEGMENsensor offers ATEX/IECEx explosion-protected versions of its level, pressure and position sensors as an option on selected models for Zone 1 and Zone 2 hazardous areas; its clamp-on flow meters are not explosion-protected.

Which level sensor works best for corrosive chemical tanks?

For corrosive chemical tanks, magnetostrictive level sensors with PVDF or Hastelloy wetted parts are the most reliable choice — providing continuous level measurement with no moving parts. Float-type sensors with PTFE-coated floats are a cost-effective alternative for less aggressive media. SEGMENsensor offers both types with PP, PVDF, and 316L stainless steel wetted materials.

Do you offer ATEX/IECEx sensors for hazardous areas?

Yes. ATEX/IECEx explosion-protected versions for Zone 1 and Zone 2 hazardous areas are available as an option on selected models — for example the flameproof SE-LX magnetostrictive level transmitters and the intrinsically safe SE-PR30 position sensor. The Ex marking is as stated on the certificate of the specified model, which is provided with the quotation.

What is the lead time for OEM sensor orders?

Standard catalog samples ship in 5–7 business days from our Shenzhen factory. Production lead time depends on model and quantity and is confirmed with the quotation. Custom OEM designs with new housing tooling are quoted on request, with first-batch lead time confirmed at order.

Can I get custom cable lengths or process connections?

Yes — all SEGMENsensor sensors are configurable for OEM projects. Cable length, jacket material (PVC, PUR, FEP), connector type (M12, M8, DIN, flying lead), and process connection thread (G, NPT, BSP, flange) are all available as custom options. Qualification samples for custom configurations are 1–5 pcs, shipped in 5–7 working days; MOQ and lead time are confirmed with the quotation.

What is the difference between a magnetostrictive and ultrasonic level sensor?

Magnetostrictive level sensors measure the position of a float magnet on a stainless steel stem using a torsional wave — highly accurate (repeatability ±0.005 mm on SGM-LS10), suitable for pressurized vessels. Ultrasonic level sensors emit sound waves from above the tank — non-contact, suitable for open tanks and aggressive media, but less accurate (±0.1–0.5%) and affected by foam or vapor. SEGMENsensor supplies both types.

Which flow meter works for high-viscosity food liquids?

Clamp-on ultrasonic flow meters suit food and beverage liquids such as juices, syrups and dairy when the pipe runs full with a single, sound-conducting liquid. The sensors attach to the outside of the pipe with no contact with the product and no process shutdown for installation. Depending on the model, SEGMENsensor clamp-on meters cover pipes from DN15 to 5000 mm (U11); very viscous products should be checked with us before ordering.

Are your sensors compatible with 4-20mA, HART, or Modbus output?

Yes. SEGMENsensor sensors are available with 4–20 mA (2-wire and 3-wire), 0–5 V, 0–10 V, NPN/PNP switching, RS485, Modbus RTU, SSI and IO-Link outputs. HART is standard on magnetostrictive sensors (2-wire 4–20 mA + HART, configurable with a HART handheld communicator) and available on selected pressure transmitter models. Custom signal conditioning is available for OEM projects.
