Product Overview

The 111-402-000-013 is a proximity measuring system from Meggitt Vibro-Meter. This device uses the eddy-current principle for non-contact measurement. It conforms to API 670 recommendations for machinery protection. The system works perfectly with VM600 and VibroSmart monitoring systems. This model has a standard environment rating with no explosion protection.

Technical Specifications

The 111-402-000-013 has a standard environment rating (A1). The body thread is M10 × 1 for easy installation. The body length is 72 mm (C072). The unthreaded length is 0 mm minimum (D000). The integral cable length is 5.0 meters with ±500 mm tolerance. This model has no flexible stainless steel hose protection. There is no flexible hose on this version. The total system length is 1 meter (H01). The total weight is only 0.22 kg.

This proximity transducer requires a high-frequency power source. You must use an IQS900 signal conditioner for proper operation. The device measures shaft relative vibration accurately. It also measures gap and position for machinery protection.

Body Configuration Details

The 111-402-000-013 features a 72 mm body length. This longer body suits deeper mounting applications. The unthreaded length is 0 mm minimum. This means the threads run almost to the transducer tip. The M10 × 1 thread provides secure and precise mounting. The stainless steel AISI 316L body resists corrosion effectively.

Performance Characteristics

The 111-402-000-013 offers a frequency response from DC to 20 kHz at -3 dB. The measurement range is either 2 mm or 4 mm depending on configuration. The design is temperature-compensated for stable readings. The output can be voltage or current with short circuit protection. This ensures reliable operation in industrial environments.

Temperature Ranges

The transducer operates from -40 to +180°C. Drift stays below 5% within this operating range. Short-term survival extends from +180 to +220°C. Drift exceeds 5% in this survival range. The cable and connector handle -40 to +200°C. For Ex zone use, the transducer and cable work from -40 to +195°C. Note that this model has a standard environment rating only.

Environmental Protection and Durability

The transducer tip and integral cable have an IP68 rating per IEC 60529. This means complete dust protection and continuous water immersion resistance. Vibration tolerance is 5 g peak between 10 and 500 Hz per IEC 60068-2-26. Shock acceleration tolerance is 15 g peak per IEC 60068-2-27. This uses a half sine wave with 11 ms duration.

The 111-402-000-013 uses an FEP sheath for chemical resistance. FEP stands for extruded fluorinated ethylene propylene. This sheath resists almost all chemicals. It offers low permeability to liquids, gases, and moisture. The material remains flexible, low friction, and mechanically tough.

Physical Construction

The transducer uses an 8 mm wire coil. The tip is made of Torlon (polyamide-imide) material. The body is encapsulated in stainless steel AISI 316L. High-temperature epoxy glue secures all internal components. The integral and extension cables are FEP covered 70 Ω coaxial cables. Each cable measures 3.6 mm in diameter. Connectors are self-locking miniature coaxial types. Always hand-tighten these connectors until they lock.

Applications for 111-402-000-013

The 111-402-000-013 is ideal for shaft relative vibration measurement. It also measures gap and position accurately. Common applications include turbines, compressors, and pumps. The system works for machinery protection and condition monitoring. It is specifically designed for API 670 applications. Use it with VM600Mk2, VM600, or VibroSmart monitoring systems.

Installation Guidelines

Mount the 111-402-000-013 using the M10 × 1 body thread. The 72 mm body length allows deeper insertion than standard models. Ensure the unthreaded 0 mm section positions correctly at the mounting surface. Tighten the mounting nut to the specified torque only. Do not overtighten or you may damage the threads. Hand-tighten all coaxial connectors until they lock securely. Protect the 5.0 meter FEP cable from sharp edges and excessive bending. Keep the cable away from extreme heat sources above 200°C. Verify the total system length of 1 meter matches your extension cable. Maintain proper gap distance as specified by your IQS900 conditioner.

Frequently Asked Questions (FAQ)

Q1: What is the advantage of the 72mm body length?
The longer body allows mounting in deeper threaded holes. The 111-402-000-013 reaches further into machinery casings.

Q2: Can I use this sensor in explosive atmospheres?
No, this model has a standard environment rating (A1). You need an Ex i version for hazardous areas.

Q3: What does 0 mm unthreaded length mean?
The threads extend almost to the transducer tip. The 111-402-000-013 has minimal smooth section before the sensing face.

Q4: Is the 5.0 meter cable field-replaceable?
No, the 5.0m integral cable is factory-attached. Do not attempt to cut or splice the coaxial cable on the 111-402-000-013.

Q5: How does the 1m total system length work with a 5m integral cable?
The 111-402-000-013 has a 5m cable from the transducer. The remaining length comes from extension cables to reach the signal conditioner.
