ML100-55/95/103 Photoelectric Through-Beam Sensor - 100m Detection IP67

Product Specification

​1. Product Overview: PEPPERL+FUCHS ML100-55/95/103 Magnetic Level Sensor

​
The PEPPERL+FUCHS ML100-55/95/103 is a high-precision magnetic level sensor designed for continuous, non-contact liquid level measurement in industrial storage tanks and process vessels. Utilizing magnetostrictive technology, this sensor provides accurate and reliable detection of liquid levels, interfaces, and temperatures in harsh environments. The ML100 series features a robust stainless steel probe (length options: 55/95/103 cm) and a float-mounted permanent magnet, enabling compatibility with a wide range of liquids, including corrosive and high-temperature media. With an IP66/67 protection rating and explosion-proof certifications, it operates seamlessly in hazardous areas such as chemical plants, oil refineries, and pharmaceutical facilities. Its modular design allows easy integration with PLCs and SCADA systems for real-time monitoring and control.

​2. Key Technical Specifications​

• ​Measuring Range: Customizable probe lengths (550 mm, 950 mm, 1030 mm).
• ​Output Signals: Analog (4–20 mA, 0–10V) + switching outputs (SPDT relays).
• ​Accuracy: ±1 mm (dependent on probe length and media).
• ​Pressure Rating: Up to 40 bar (depending on model).
• ​Temperature Range: -40°C to +150°C (media), -40°C to +85°C (ambient).
• ​Housing Material: Stainless steel (1.4404/316L) or PTFE-coated for aggressive media.
• ​Protection Class: IP66/IP67, Ex d/IIC T6 (ATEX/IECEx certified).
• ​Power Supply: 24V DC (±10%).

​3. Industrial Applications and Use Cases

​
The ML100-55/95/103 is widely deployed in chemical processing plants for monitoring acid or solvent levels in storage tanks. In oil and gas, it ensures precise level control of crude oil, LNG, or hydraulic fluids in offshore platforms and refineries. The food and beverage industry uses it for hygienic liquid level measurement in CIP (Clean-in-Place) systems. Its explosion-proof design makes it ideal for hazardous environments like fuel depots and biogas facilities. Additional applications include wastewater treatment for sludge level detection and pharmaceutical production for bioreactor volume monitoring.

​4. Competitive Advantages and Unique Features​

• ​High Precision: Magnetostrictive technology ensures ±1 mm accuracy for critical processes.
• ​Durability: Stainless steel or PTFE-coated probes resist corrosion, abrasion, and aggressive chemicals.
• ​Multifunctional: Simultaneous measurement of level, temperature, and interface layers (oil/water).
• ​Safety Compliance: ATEX/IECEx certifications for Zone 0/1 hazardous areas.
• ​Low Maintenance: Non-contact design eliminates wear and reduces lifecycle costs.

​5. Functional Capabilities and Operational Benefits

​
The sensor’s analog output provides continuous level data for precise inventory management, while relay outputs trigger alarms or pump controls to prevent overfill or dry runs. Its temperature compensation ensures stable performance despite thermal fluctuations. The modular electronics allow field configurability via HART protocol or local interface. By integrating with IoT platforms, it supports predictive maintenance and reduces downtime. With a lifespan exceeding 10 years in harsh conditions, the ML100-55/95/103 optimizes operational safety and efficiency, making it a cost-effective solution for Industry 4.0-ready facilities.
