About LEICA DD

Leica DD is a line of underground utility locators and accessories developed by Leica Geosystems, a company with a long history in precision measurement and geospatial technology. The DD series is designed to detect and trace buried metallic pipes and cables, supporting applications in construction, utility maintenance, and underground infrastructure mapping. The product family includes receivers, transmitters, and kits that operate at various frequencies and offer different depth capabilities. 3G Electric supplies the Leica DD line globally, providing access to these instruments and related accessories for plant engineers, maintenance managers, and procurement specialists.

The Leica DD portfolio includes several models, such as the DD120, DD130, and DD300, each with distinct specifications. For example, the DD120 operates at 50 Hz or 60 Hz with a maximum locating depth of 10 ft and an IP54 rating, while the DD130 supports multiple frequencies (33 kHz, 8 kHz, 512 Hz, and 640 Hz) and offers a depth of up to 9.99 m. The DD300 series extends the depth to 32.8 ft and carries an IP65 rating, suitable for more challenging environments. Transmitters like the DA175 apply a 640 Hz signal to buried lines, and accessories such as carrying cases and trace rods complement the locators. These instruments feature digital displays, audible alerts, and testing modes including Active with Transmitter, Passive Power, and Passive Radio (RF). The IP ratings indicate resistance to dust and water, with IP54, IP65, and IP67 variants available across the range.

3G Electric supports the Leica DD line by stocking a selection of locators, transmitters, and kits, and by providing specification details and quotation services. The product range covers common locating frequencies and depth capabilities, allowing users to select equipment based on site conditions and target utilities. For technical buyers, the availability of multiple models with varying IP ratings and testing modes facilitates matching the instrument to the application. 3G Electric's role is to supply these products with accurate part numbers and specifications, ensuring that procurement aligns with operational requirements. The company serves a global customer base, shipping Leica DD equipment to various regions without geographic restrictions.

Frequently asked questions

Common questions about LEICA DD from 3G Electric.

What is the maximum locating depth of the Leica DD300?

The Leica DD300 has a maximum locating depth of 32.8 ft (10 m). This depth is achievable under optimal conditions and may vary based on soil properties, target material, and signal strength. The DD300 operates in Passive Radio (RF) mode at 33 kHz and is IP65 rated for dust and water resistance. It is part of the DD300 series, which includes packages such as the DD300 Depth Package and DD300 Plumbers Package, offering different configurations for specific locating tasks.

What frequencies does the Leica DD130 support?

The Leica DD130 supports multiple frequencies in active mode with a transmitter: 33 kHz, 8 kHz, 512 Hz, and 640 Hz. It also operates in Auto Mode at 33 kHz and supports Passive Radio (RF) testing. This range allows the DD130 to trace a variety of buried metallic utilities, including pipes and cables. The receiver has a maximum locating depth of 9.99 m and an IP54 rating. It is available as a standalone unit or as part of kits such as the DD130 Plumbers Kit.

What is the difference between the Leica DD120 and Leica DD130?

The Leica DD120 and DD130 differ in frequency support, depth capability, and testing modes. The DD120 operates at 50 Hz or 60 Hz with a maximum depth of 10 ft and an IP54 rating. It features Auto testing modes and is available as the DD120 DEPTH KIT. The DD130 supports active transmitter frequencies of 33 kHz, 8 kHz, 512 Hz, and 640 Hz, with a maximum depth of 9.99 m. It also offers Auto Mode at 33 kHz and Passive Radio (RF) testing. Both have digital displays and audible alerts, but the DD130 provides more frequency options for complex locating tasks.

What is the purpose of the Leica DD DA175 transmitter?

The Leica DD DA175 is a utility line signal transmitter that applies a 640 Hz signal to buried pipes or cables. This signal is then detected by a compatible receiver, such as those in the Leica DD series, to trace the line. The DA175 has a maximum locating depth of 10 ft and an IP67 rating, making it resistant to dust and water. It includes a carrying case and receiver, and features audible and digital display alerts. The transmitter is used in active locating modes to enhance signal detection on metallic utilities.

What IP ratings are available across the Leica DD range?

The Leica DD range includes instruments with IP54, IP65, and IP67 ratings. For example, the DD120 and DD130 have IP54 ratings, the DD300 has an IP65 rating, and the DA175 transmitter has an IP67 rating. These ratings indicate the level of protection against dust and water ingress. IP54 offers limited dust protection and resistance to water splashes, IP65 provides dust-tight protection and resistance to water jets, and IP67 offers dust-tight protection and resistance to temporary immersion. The appropriate rating depends on the environmental conditions of the locating task.

What testing modes are available on Leica DD locators?

Leica DD locators support various testing modes, including Active with Transmitter, Passive Power, Passive Radio (RF), and Auto. Active with Transmitter mode uses a transmitter to apply a signal to a target line, while Passive Power mode detects electromagnetic fields from energized power cables. Passive Radio (RF) mode detects radio signals that may be induced on buried conductors. Auto mode automatically selects the optimal frequency or mode. Specific models offer different combinations: for instance, the DD120 has Auto and Power modes, the DD130 supports Active with Transmitter and Passive Radio (RF), and the DD300 operates in Passive Radio (RF) or Active with Transmitter.
