2 General description

2.1 Intended use

The sondes described in this document are intended for locating, calibrating, and identifying ducts, pipes, cavities, and their blockages. These sondes are short range battery-operated inductive transmitters which can be located with a receiver operating on the same frequency. Most professional cable locators can be used to locate the sondes. The 33 kHz (32768 Hz) sondes are intended to be used inside non-conductive ducts, cavities, and structures. 512 Hz sondes can also be used inside some conductive objects, such as cast-iron or nonmagnetic stainless-steel pipes with slightly reduced range. Other metals reduce the range of 512 Hz sondes even further. Sondes are intended for professional use only. Refer to specifications for details about your sonde model.

2.2 Sonde PL18-33 and MegaSonde PL42-05

ATTENTION: These sondes generate magnetic field that is considered safe in professional use. To avoid inconvenience, it is advisable to keep implanted cardiac devices, metallic implants, and magnetic media at a minimum distance of 5 cm from operating device.

3 Operating sondes

3.1 Installing battery in NanoSonde MPL4-33

DANGER: Contains small objects and small batteries. Risk of death or personal injury. Keep out of reach of children.

3.2 Installing battery in MPL6-33, VMS6-33, MPL7-33, MPL9-33, PL18-33,

or PL18-05

Follow this procedure to install a battery:

1. Screw the battery compartment open.
2. Insert battery. Observe polarity.
3. Close the battery compartment. Tighten VMS6-33, MPL7-33, PL18-33 and PL18-05 until the O-ring is fully covered.

3.3 Installing batteries in MegaSonde PL42-05

Three different types of batteries may be used with MegaSonde PL42-05: IEC LR6 alkaline, IEC HR6 NiMH or IEC FR6 Li-FeS2. Ambient temperature, required operating time, environment and economy should be considered when selecting batteries. Disposable FR6 Li-FeS2 batteries are the lightest and have the longest battery life but are rather expensive. Rechargeable HR6 NiMH batteries are an all-round good choice. Low cost LR6 alkaline batteries should only be used at ambient temperatures above +5°C.

Follow this procedure to install batteries into MegaSonde PL42-05:

1. To open, hold battery compartment and rotate sonde anticlockwise.
2. Pull out battery holder.
3. Insert eight batteries of the same type into the battery holder according to the markings.
4. Connect the battery holder to the device. To avoid connector damage, hold the sonde vertically when connecting or disconnecting the battery holder with batteries.
5. Close the battery compartment. Tighten until the O-ring is fully covered.

3.4 Testing correct operation

When the battery is inserted, the sonde will start emitting a signal. The location of the sonde can now be detected with a receiver that operates at the same frequency. Before use, ensure both your sonde and your receiver are fully functional by locating the sonde with a receiver at the desired operating distance. Refer to section 2.4: Electrical specifications for information about operating frequency and operating range of your specific sonde model. For information about pinpointing sondes, refer to the receiver information for use.

3.5 Selecting a delivery method

All Vesala sondes have a mounting thread for connecting accessories. There are several methods to send sondes to their intended location. Refer to section 2.3: Mechanical specifications for more information on what limiting values and what mounting thread size your sonde has. Blowing a sonde along a duct with compressed air is called jetting. It is the only option when calibrating long micro ducts with sondes. Only light weight sondes may be jetted. Please note that PL18-05 and PL42-05 should not be jetted due to their weight and PL18-33 may only be jetted at lower speeds. Pushing or pulling a sonde with a cable rod is called rodding. It is a suitable method to deliver heavier sondes for relatively short distances. Please note that MPL4-33 cannot be rodded due to its delicate construction. MPL6-33, VMS6-33 and MPL7-33 may only be rodded with limited rodding force. Other methods include floating or flushing a sonde thru a pipe with water or hanging it from a string. PL42-05 has an integrated string attachment point for that purpose. Please note that pressurised water may not be used to flush MPL4-33.

3.6 Jetting

WARNING: Compressed air is used to propel sondes when jetting. Risk of personal injury or property damage. Do not stress equipment beyond their maximum values. Wear a face shield. Wear head protection. Refer to section 2.3: Mechanical specifications for more information on the maximum values of your sonde model. Refer to jetting machine or air compressor information for use for more information on their proper use.
Follow this procedure to safely jet sondes thru ducts:

1. Attach a suitable sonde catcher to the end of the duct. A sonde may exit the duct at a dangerous speed. A proper sonde catcher reduces both the risk of damaging the sonde and the risk of damage inflicted by the sonde.
2. To reduce wear, dispense a suitable amount of jetting lubricant into the duct and blow a cleaning sponge thru to the sonde catcher.
3. Attach a shock absorber to the sonde. A shock absorber reduces the acceleration caused by a collision with a blockage. It also enables jetting small sondes at a higher speed compared to jetting without a shock absorber.
4. Attach a calibrator to the shock absorber if not already attached. A calibrator allows sondes to stop at damaged duct sections so that they can be located and repaired.
5. Install battery and test correct operation.
6. Feed the sonde into the duct shock absorber first.
7. Feed a sponge behind the sonde. This allows the use of lower air pressure.
8. Connect air supply to the duct. Limit air pressure to a safe level that all the connected equipment can tolerate. Gradually increase the air flow to a level that reliably propels the sonde forward at a moderate speed. Track the approximate location of the sonde as it travels along the duct and adjust air flow as needed.
9. When the sonde reaches the catcher, immediately cut air flow. Then remove the sonde from the catcher.
10. If the sonde jams, cut air flow. Locate the sonde and expose the duct. Take care not to cut the duct exactly at the sonde. Instead, remove a duct section containing the sonde and carefully remove the sonde using minimal force preferably to the direction it came from. If the sonde cannot be located and you attempt to jet it backwards, move the catcher to the other end of the duct. Do not attempt to dislodge any sonde with a pressure exceeding 10 bar.

3.7 Rodding

Rodding may wear sondes quickly especially when sondes are used inside concrete, ceramic, or metallic pipes. To reduce wear, do at least one of the following:

• Use a protective non-conductive cover over the sonde.
• Use a flexible mount between the sonde and the rod.
• Wash the pipe.
• Lubricate the pipe.

Use the following procedure when rodding:

1. If the pipe has tight corners or obstacles, install a flexible mount between the sonde and the rod.
2. Install battery and test correct operation.
3. Attach the sonde to the rod.
4. Push the sonde forward using a force that does not exceed the maximum rodding force of your sonde. Refer to section 2.3: Mechanical specifications for more information on the maximum values of your sonde model.
5. Track the approximate location of the sonde as it travels along the pipe.
6. When the sonde reaches the desired location, pinpoint its location precisely.
7. Remove the sonde before attempting to perform operations to the pipe.
8. If the sonde jams and cannot be dislodged, locate the sonde, and expose the pipe. Take care not to cut the pipe exactly at the sonde. Instead, remove a pipe section containing the sonde and carefully remove the jammed sonde using minimal force preferably to the direction it came from. Do not attempt to dislodge a sonde with force exceeding its specified maximum rodding force.

3.8 Cleaning

If the device is dirty or wet, clean and dry the outer surface of the device with a soft cloth before opening the battery compartment. Avoid getting dirt or water inside the device. Isopropanol may be used to remove stains and disinfect the surface. Battery contacts should only be cleaned with isopropanol and a soft, lint free cloth.

3.9 Storing

Remove batteries or disconnect battery holder immediately after each use. It is highly recommended to store the device, batteries, and accessories inside their original packaging in a dry, warm place.

4 Taking care of your equipment
