PT3
Automatic Judgement of Inspection Results
Automatically performs a simple judgement of steam trap operating conditions and whether there is internal seat leakage in valves installed on fluid piping. Also effective for confirming valve closure.
Steam Trap Operation Inspection Results
| Steam Trap Operation Inspection | |
|---|---|
| Good | The surface temperature is sufficient and almost no ultrasonic sound is detected, indicating normal operation. The LED flashes green and turns off when any button is pressed. |
| Caution (only when selecting Model Name [Other]) | Not blocked, but it is difficult to judge whether the condition is normal or leaking; continued observation is recommended. The LED flashes yellow and turns off when any button is pressed. |
| Leak (only when selecting Model Name [Other]) | Strong ultrasonic sound is detected, indicating a high possibility of leakage. The LED flashes red and turns off when any button is pressed. |
| Leak/L (applicable for a selection of TLV models) | There is a high possibility of leakage with a relatively large leakage rate. The LED flashes red and turns off when any button is pressed. |
| Leak/S (applicable for a selection of TLV models) | There is a high possibility of leakage with a relatively small leakage rate. The LED flashes yellow and turns off when any button is pressed. |
| Blocked | The measured surface temperature is below 40 °C, indicating a high possibility of blockage. The LED flashes red and turns off when any button is pressed. |
| Low temp. (excluding temperature control type) | The trap surface temperature has dropped due to condensate accumulation, inlet pressure drop, a closed inlet valve, or blockage in the inlet piping, etc. The LED flashes red and turns off when any button is pressed. |
| Fail adj.-H (temperature control type only) | The surface temperature is excessively high relative to the set temperature. The LED flashes red and turns off when any button is pressed. |
| Fail adj.-L (temperature control type only) | The surface temperature is excessively low relative to the set temperature. The LED flashes red and turns off when any button is pressed. |
Valve Internal Leak Inspection Results
| Valve Internal Leak Inspection | |
|---|---|
| Good | No ultrasonic sound is detected, or ultrasonic sound is detected but is external (ambient) ultrasound; there is a high possibility that valve leakage is not occurring. The LED flashes green and turns off when the screen transitions to Valve Inspection mode. |
| Caution | It is difficult to judge between normal and leaking conditions; continued observation is recommended. The LED flashes yellow and turns off when the screen transitions to Valve Inspection mode. |
| Leak | Strong ultrasonic sound is generated at the valve body, indicating a high possibility of leakage. The LED flashes red and turns off when the screen transitions to Valve Inspection mode. |
Bearing Inspection
By measuring shock pulses generated when bearing damage has occurred or when the rotating machinery is not sufficiently lubricated, you can understand the deterioration condition. Use this for collecting data for daily trend monitoring.
Reading RFID Tags
To read an RFID tag with the PT3, link with the CMRecorder mobile app, then position the RFID reader (located near the LED on the bottom of PT3) close to the RFID tag.
* RFID tags cannot be read from the Digital Stethoscope located on the top of the unit.
User-Defined Fields
Integration with the CMRecorder mobile app allows users to set custom measurement types with user-defined fields. This is useful when you want to measure and log vibration acceleration levels or surface temperature at inspection points other than steam traps, valves, and bearings, or record other specific information to match site requirements.
Digital Stethoscope (Audio Monitoring)
PT3 allows users to listen to sounds from the inspection target by connecting Bluetooth earphones. Surface temperature and average vibration acceleration level can also be checked simultaneously.
* Make sure to use a safe volume level when listening via Bluetooth earphones.
PT3 Features
Measures Vibration and Surface Temperature Simultaneously
Both an ultrasonic sensor and a temperature sensor are built into the probe tip. Vibration acceleration and surface temperature are measured at the same time.
Automatic Start, Automatic Stop
Simply press the sensor against the measurement target to start measuring automatically. Measurement ends automatically after a set period of time.
* The power must be ON.
* In Bearing measurement mode, measurement ends when the sensor is removed from the measurement target.
Recharge via USB Cable
Rechargeable via a USB Type-C cable.
Up to 3 days of continuous use on a single charge, and can also be used for firmware downloads.
