TLV PT3 Pocket TrapMan® is a pocket-size diagnostic instrument designed for the rapid and accurate inspection of steam traps, valves, and bearings. By measuring high-frequency ultrasonic sound and surface temperature simultaneously, it detects leaks, blockages, and mechanical wear that are otherwise imperceptible to human senses. The instrument features a rugged IP54 housing, explosion-proof certification for hazardous areas, and Bluetooth connectivity for seamless data management via the CMRecorder mobile application.

Principles of Operation

Generation of Ultrasonic Sound (Steam Traps and Valves) When fluid leaks through the seat of a steam trap or valve, it emits high-frequency ultrasonic sound. Because this sound is generated by leak volumes too small to be noticed by human perception, ultrasonic monitoring enables the early detection of deteriorated equipment.

Ultrasonic Shock Pulse Generation (Bearings) Shock pulses are generated when metals collide, such as race contact in bearings due to insufficient lubrication or wear. The PT3 measures the intensity of these shock pulses to determine the operational condition of the bearing.

Surface Temperature Measurement The device measures surface temperature and ultrasonic sound simultaneously. Temperature data is essential for detecting blockages in steam traps and assessing bearing conditions.

Temperature Restrictions

The allowable surface temperature range is -40 to 350 °C. Exceeding 350 °C may damage the probe tip or internal components. The device will flash rapidly and display "OVER" if this limit is exceeded.

Functions and Features

• Trap Inspection: Automatically inspects steam traps and provides a judgment estimate (Good, Caution, Leak, Leak/L, Leak/S, Blocked, Low Temp., Fail adj.-H, Fail adj.-L).
• Valve Seal Inspection: Simultaneously measures vibration and surface temperature to evaluate the valve's seal condition (Good, Caution, Leak).
• Bearing Deterioration Inspection: Collects operational characteristic data, calculating Average values, Peak values, and Crest Factor (CF) to identify lubrication failure or mechanical damage.
• User-Defined Inspection: Collects vibration and temperature data for custom equipment points.
• Audio Monitoring: Allows the user to listen to equipment sound via Bluetooth earphones while monitoring average temperature and acceleration levels.
• RFID Tag Reader: Scans RFID tags to quickly link measurement records to specific plant locations in CMRecorder.

Safety in Hazardous Areas

DO NOT replace or charge the battery in hazardous areas. Use only explosion-proof certified Bluetooth earphones when operating in hazardous locations. Failure to observe these precautions may result in explosion, fire, or injury.

Measurement Limitations

Certain steam traps cannot be accurately evaluated due to their operational conditions. The device is not recommended for:

1. Traps affected by high velocity steam flow noise (e.g., TLV-COSPECT, TLV-DC3S, drip legs at pressure reducing stations/turbines).
2. Very high-pressure applications (greater than 8.0 MPaG / 80.0 kg/cm²).
3. High capacity traps discharging more than 3,000 kg/h of condensate.
4. Traps operating below 0.05 MPaG (0.5 kg/cm²G) or with a differential pressure less than 0.05 MPa, due to low ultrasonic wave frequencies.
