Measurement value: The effective value (rms) of the vibration velocity (mm/s).
Approvals: CE, ATEX, EAC, EAC EX, IEC, IEC Ex, SIL2 / PL-d (TÜV-Süd), C UL.

High Sensitivity for Critical Vibration Detection

The HE250 Series provides accurate, real-time vibration level measurements critical for preventive maintenance. Its 10% accuracy ensures reliable detection of mechanical issues in rotating equipment, reducing downtime and supporting overall operational safety within hazardous environments.

Rugged Construction for Demanding Conditions

Built with corrosion-resistant 316L stainless steel and rated to IP68, this sensor performs exceptionally in both humid and harsh industrial environments. Its design ensures reliable operation across a wide temperature range from -40C to +85C, making it an optimal choice for challenging applications.

ATEX Certification for Intrinsic Safety

The HE250 Series meets ATEX standards, making it inherently safe for deployment in explosive or hazardous areas. This feature is essential for industries requiring strict adherence to safety and compliance regulations.

FAQ's of ATEX vibration sensor HE250 series:

Q: How is the HE250 Series vibration sensor installed in industrial setups?

A: The sensor can be mounted using either a fixed base or a stud, depending on specific equipment requirements. Custom and standard mounting sizes (M8, M12, M16) are available, and installation should be done in accordance with ATEX safety guidelines for hazardous locations.

Q: What makes the HE250 Series suitable for hazardous and humid environments?

A: It features a 316L stainless steel enclosure and is rated IP68, offering exceptional resistance to corrosion, water ingress, and harsh environmental conditions. This robustness ensures long-term reliability in facilities with exposure to moisture, chemicals, or dust.

Q: When should the HE250 Series be used for vibration monitoring?

A: This sensor is ideal for continuous vibration detection in pumps, motors, and compressors located in ATEX-rated hazardous zones. It is best utilized for predictive maintenance applications to anticipate and address issues before they lead to equipment failure.

Q: Where can the HE250 Series vibration sensor be applied?

A: The sensor is designed for use in industries such as oil and gas, chemicals, manufacturing, and power generation-anywhere vibration monitoring within explosive or intrinsically safe environments is required. It is available throughout India via authorized distributors and suppliers.

Q: What process does the HE250 Series use to measure vibration?

A: It employs a piezoelectric accelerometer that detects vibrations and outputs a proportional 4-20 mA analog signal. This signal can be easily integrated with monitoring and control systems for real-time data analysis and maintenance planning.

Q: How does electrical isolation benefit the sensor's operation?

A: The sensor is fully electrically isolated, which helps to prevent ground loops and electrical interference, ensuring accurate measurement outputs and protecting both the sensor and connected monitoring equipment.

Q: What are the key benefits of using the HE250 Series vibration sensor?

A: Key benefits include robust ATEX-certified safety, versatile mounting and connectivity options, high measurement accuracy, and adaptability to harsh environments. These features help prevent unscheduled downtime and extend the lifespan of critical industrial machinery.
