Choosing RD Locator Transmitters, Clamps and Accessories
Choosing the receiver first? Compare RD7200 and RD8200 family receivers before building the rest of the system.
Build a locating kit around the task, the receiver and the signal method. A transmitter clamp applies a signal; a receiver clamp helps identify one. An A-Frame investigates faults, while a sonde provides a signal inside a pipe or duct. These accessories do different jobs and are not interchangeable.
Start with the full receiver model, transmitter version and accessory part number. RD7000, RD7100, RD7200, RD8000, RD8100 and RD8200 span different generations and configurations. A familiar connector or similar product name is not enough to establish every function.
Tx5, Tx10 or Tx10B?
| Transmitter | Documented distinction | Buying check |
|---|---|---|
| Tx5 | 5 W maximum output in the current specification, with supported active locating and 8 kHz fault-find signals. | Match the available signal to the receiver and task; do not infer iLOC from a generic Tx5 name. |
| Tx10 | 10 W maximum output and documented Current Direction signal support. | A CD signal still needs a CD-capable receiving system. |
| Tx10B | The current specification identifies the Tx10B iLOC variant separately. | Choose a compatible iLOC receiver and transmitter pairing when remote control is required. |
Maximum output power is not a guaranteed tracing distance or detection depth. The usable signal depends on the connection, service, frequency, ground and interference. Legacy Tx variants can differ: compare the instrument's exact version with the applicable specification rather than transferring a current feature to every older unit.
Transmitter clamp or locator clamp?
A transmitter signal clamp connects to the transmitter and applies its signal to a suitable cable or pipe. A locator clamp connects to the receiver and helps investigate the response on an accessible utility. Select the correct role, compatible frequency, connector and aperture for the job.
Current Direction accessories need the appropriate CD signal and CD-capable receiver. A standard receiving accessory does not gain CD information merely because a Tx10 is nearby. Follow the equipment's safe-use instructions; a clamp is not protective equipment for handling exposed conductors.
When is an A-Frame useful?
The A-Frame is a ground-contact accessory for investigating cable sheath faults or pipeline coating defects. Both the receiver and transmitter must support the required fault-find method. Match the mode on both devices; having a receiver that traces the line does not by itself establish a complete fault-finding system.
Sondes and traceable rods serve a different task
A sonde supplies a signal from a point inside a suitable pipe or duct. The receiver needs the exact sonde frequency and a supported sonde mode. A traceable rod system may let you trace a route or locate its tip, depending on the system and connections. Follow its power limits and connection instructions rather than applying a transmitter's maximum output by default.
Use the existing sonde selection and compatibility guide for that choice. A sonde is not needed to replace every standard line-tracing task.
Power and carrying accessories
Receiver and transmitter battery packs and chargers are separate systems. Match the exact pack, charger, connector and supported generation. A battery tray, rechargeable pack, mains charger and complete charging kit are different purchases; the contents list determines what is supplied.
Choose bags and cases by the equipment they accommodate, including fitted batteries and planned accessories. A case protects equipment during storage and transport; it does not change the instrument's locating performance or make an unsupported accessory compatible.
What belongs in the order?
- Exact receiver and transmitter versions, with the required shared frequencies.
- The right connection or clamp accessories for the intended method.
- Any separately required fault-find or sonde equipment.
- Compatible batteries, chargers and carrying equipment.
- Clearly itemised supplied contents, with optional additions priced separately on the offer.
