Considerations for selecting intrinsically safe position sensors
When choosing intrinsically safe position sensors for your application, several important factors should be considered to ensure optimal performance and compliance with safety regulations:
- Hazardous area classification: Identify the hazardous environment where the sensor will be used. Ensure the sensor is certified for the appropriate classification (e.g., ATEX, IECEx) to guarantee safe operation.
- Measurement range and type: Determine the required measurement range and type of displacement (linear, angular, etc.) for your application to ensure reliable performance.
- Output signal compatibility: Choose from various output types, such as analog voltage, current, or digital signals. Ensure compatibility with your control systems for effective integration.
- Environmental conditions: Consider environmental factors like temperature, humidity, and mechanical stress. Select a sensor designed to withstand these conditions while maintaining accuracy.
- Mounting and installation requirements: Assess the sensor's dimensions and mounting options to ensure easy installation without compromising safety or functionality.
- Response time and sensitivity: For applications requiring real-time feedback, select sensors with fast response times to ensure timely data collection.
By thoughtfully evaluating these factors, you can choose the ideal intrinsically safe position sensor to meet your specific requirements. This will ensure reliable operation, compliance with safety standards, and accurate measurements in hazardous environments.

Frequently asked questions about Intrinsically safe position sensors
Answers to the most important technical Questions
Which ATEX or Ex certifications are available for intrinsically safe inductive displacement transducers and probes?
Depending on the design, intrinsically safe inductive displacement transducers and probes are available with ATEX, IECEx or CSA approvals. Althen offers intrinsically safe position sensors for hazardous environments where flammable gases, vapors or dust may be present.
These sensors are available for hazardous area classifications such as Ex II 1G, Ex II 1GD and Ex i/II M1/1GD.
The required certification depends on the application, hazardous area classification and country of use. ATEX is generally relevant for European applications, IECEx is commonly used for international projects, and CSA or UL approvals may be required for North American markets.
We will be happy to help you select the right sensor and Ex certification for your application.
What should I consider when selecting an intrinsically safe inductive displacement transducer?
When selecting an intrinsically safe inductive displacement transducer, you should first determine the hazardous environment for which the sensor must be approved: gas, vapor, dust, Zone 0/20, or other hazardous areas. Althen offers models with ATEX, IECEx, UKEX, CSA, or other Ex approvals for demanding environments. The required measuring range, installation situation, and environmental conditions are also important. Depending on the model, customized strokes from a few millimeters up to 800 mm are possible; some versions are also available for longer measuring ranges. Pay attention to the protection rating and robustness: many sensors feature stainless-steel housings with IP65/IP67, while submersible versions achieve IP68/IP69K and, depending on the design, can also be used under high pressure. For precise and durable measurements, linearity, temperature stability, EMC immunity, vibration and shock resistance, and the appropriate output signal should also be considered. Many intrinsically safe inductive displacement transducers from Althen operate contactlessly, are wear-free, offer very high resolution, and typically provide a ratiometric analog output signal of 0.5–4.5 V. Depending on the sensor type, a suitable galvanic isolation amplifier such as the Althen X005 or G005 may be required for safe operation and reliable signal transmission. The decisive factors are Ex approval, measuring range, protection rating, mechanical integration, environmental conditions, output signal, and suitable evaluation electronics. If standard versions do not fit exactly, we can also support you with customized designs and complete measurement solutions.
