Using a Sonde Transmitter


One should never dig or drill into the ground without first checking for utility lines. Underground utility lines pose a threat to one’s safety. Thousands of emergencies are reported each year due to people hitting a utility line.

To prevent any issues, one should use a sonde transmitter. This device can be used to locate non-metal underground utilities. Using this device is a must.

Read on to learn more about the sonde transmitter, so you know how it works.

What Is a Sonde Transmitter?

A sonde is a radio transmitter that can be used to locate non-magnetic utilities that are underground. These types of utilities include gas and water pipes. A sonde transmitter can also help locate storm drains and conduits.

This device can come in handy in several situations. It’s perfect for projects that require digging or drilling a hole. When it comes to these projects, safety is key, so using a sonde can help prevent a major incident.

How Do Sondes Work?

If you plan to use a sonde, you must know it works. The transmitter emits an electromagnetic (EM) field. It’s emitted at around 512 Hz, which is the standard frequency in the United States.

The EM field will move along with the sonde transmitter. Both will travel through the pipeline. It then emits a signal.

The operator of the utility locator will be able to see the signal. The operator can use either an EM locator or receiver to detect the transmitter’s location. The operator will then mark its location.

The beauty of this utility locating device is that it allows the operator to remain above ground. It does have one drawback. The sonde’s signal is limited.

So, what does this mean for the user of the sonde? It means that the operator should have a general idea of where the underground utility location is before digging.

How to Operate the Sonde?

There’s a specific process an operator must follow to use this device. The operator must first insert the sonde into a non-metal pipe. This can be done through a cable.

After completing this step, the operator will use the locator to find the sonde’s signal. Doing this will then enable the operator to mark the position of the pipe.

The operator will then push the sonde further down the pipe. The receiver will then help the operator relocate the transmitter. Once again, the operator can mark where the pipe is.
