Leica Signal Clamp

The Leica Signal Clamp is a 100mm (4-inch) transmitter accessory that allows you to induce a tracing signal onto metallic pipes and live cables safely. Compatible with Leica DA transmitters, it enables precise utility identification and depth estimation. Its robust, spring-loaded design ensures a constant signal connection even on larger utilities.

Inductive Line Energizing: Applies a dedicated tracking signature to steel utility pipes safely without stopping standard building services.
Corrosion Proof Pivot: Designed with a resilient hinge mechanism that opens wide to snap easily around dirty excavation lines.
Shielded Structural Cord: Features a thick polyurethane jacket to protect internal copper wires from sharp trench stones.
Consistent Signal Induction: Delivers uniform magnetic induction across the full diameter of the targeted service pipe.

Full Description

The Leica Signal Transmitter Clamp is an indispensable tool for professional utility tracing. When direct connection to a cable's core is either impossible or unsafe, the clamp provides a reliable alternative by inducing a signal through the outer sheath. This is the preferred method for tracing live electrical cables or telecom lines where service interruption is not an option. The 100mm jaw capacity is designed to accommodate the majority of standard utility pipes and cable bundles found on construction sites. By "clamping" around the utility, the signal from your DA230 or DA300 transmitter is concentrated directly onto that specific line, minimizing signal "bleed" onto nearby services. This results in a cleaner, more accurate trace for your DD series locator. Built for the field, it features a heavy-duty spring mechanism for a secure grip and a durable lead that withstands the rigors of daily site use.

FAQs

Can we hire this unit for short-term projects?

Yes, the Leica Signal Clamp is available for flexible short-term or long-term hire, allowing you to easily add active tracing capabilities to your current equipment kit.

What is the primary function of the Leica Signal Clamp?

The clamp connects to a DA signal generator to safely apply an active tracing frequency onto insulated live cables or metallic pipes without disconnecting the utility or interrupting the supply.

Does the clamp require a direct electrical connection to the internal conductor?

No, it utilizes an internal toroidal winding that creates an electromagnetic field, inductively inducing the tracing signal onto the internal metal conductor through the cable insulation.

What size options are available for this accessory?

The standard Leica signal clamp features a 100mm internal diameter, which accommodates the vast majority of standard utility pipes and high-voltage electrical cable bundles.

Can it be used to trace non-conductive plastic utility lines?

No, the clamp induces an electromagnetic signal that requires a continuous metallic path to travel; it cannot transmit a signal along a plain plastic or clay pipe.

Must the clamp jaws be completely closed to work?

Yes, for correct signal transfer, the jaws must snap fully closed around the utility; any gap in the clamp’s circular loop will significantly reduce the tracking signal strength.

How does it connect to the transmitter unit?

The clamp is equipped with a heavy-duty cable and a dedicated plug that inserts directly into the accessory output socket of a Leica DA220 or DA300 signal generator.

Is this accessory safe to use on live high-voltage power cables?

Yes, the clamp body is fully insulated and explicitly engineered to safely wrap around live electricity cables, providing a secure
