Product Description

subsite-250-pipe-cable-locator-receiver

The Subsite 250 pipe and cable locator / Cable Avoidance Tool (CAT) offers a simple and safe solution to finding and tracing buried services up to a depth of 4.6 metresGet a grip on what’s beneath your feet with the 250R/T system, one of the most efficient and cost-effective methods for locating and avoiding buried telephone, CATV, power, gas, and water lines. Consisting of a 250T transmitter and a 250R receiver with passive or active capabilities, this simple, safe, light-weight system features intuitive controls, an easy-to-read display, and depth estimation up to 4.6 m. Whether you use it passively or actively, the 250R/T will help you get a handle on any situation.

The Subsite 250 R/T pipe and cable locator operates on the principle of detecting electromagnetic emissions from metallic services

  • Audible and visual display for use in noisy conditions with operator friendly controls and high visibility instruction labels.
  • Power mode is used to locate all live cables with sufficient current flow.
  • Radio mode is used to locate any metallic service carrying a (VLF) very low frequency signal.
  • Active mode is used in conjunction with the Transmitter to locate and trace a specific service which is an Optional Accessory

The Subsite 250 pipe and cable locator / Cable Avoidance Tool (CAT) was designed and built after consultation with engineers who used this type of equipment everyday.

Features

  • Simplified digital controls are arranged for easy operation.
  • Display is backlit & reinforced with a scratch-resistant coating for optimal visibility day, night, & well into the future.
  • Best-in-class dynamic range means the 250R/T can locate even when signals are extremely weak or strong.
  • Rugged design and moisture resistant cases stand up to long term use and tough weather conditions; housings are up to 2.5 times thicker in wearable areas than similar models.
  • Tones are derived from the actual signals radiating from pipes or cables, so even novice users can distinguish the signal from background noise.
  • Manufactured with 2/3 fewer components than similar models; fewer mechanical and electrical connections mean greater reliability.
  • With 1 Watt of power, the 250T is ten times more powerful than other transmitters in its class. It can apply 33-kHz signals via direct connect, induction clamp, or other optional accessories.

Note :
1 Power mode is used to locate all live cables with sufficient current flow
2 Radio mode is used to locate any metallic service carrying a (VLF) very low frequency signal
The 250 has a specifically strong radio mode signal which makes it a very popular model
3 If the Metallic Pipe has a Current then the 150 can detect it in Power Passive mode
4 Active mode is used in conjunction with the Transmitter to locate and trace a specific service.
The Transmitter is an Optional Accessory
5 The 950 has a large range of Transmitter frequencies which is used when cables are congested and there is a chance of “bleeding” i.e. current jumping from one cable to another
6 Beacon Mode is used for Non Metallic pipes where you create a signal by inserting the beacon / sonde into the non-metallic pipe e.g asbestos, PVC or plastic The beacon is an optional accessory and needs to be purchased separately
