Electromagnetic Transmitters

Electromagnetic Transmitters

OEL Electromagnetic transmitters will operate effectively in buried pipelines, pipelines carrying gas or liquids and in pipeline bundles where acoustic pingers are either less effective or ineffective. The transmitters have optimum signal range and the operator can select between continuous and pulsing modes. The continuous mode is required when the system is being used to signal the passage of a pig, in most other applications the pulsing mode is advantageous and provides greater operational battery life. The transmitter emits a 22Hz signal and the inherent EM null spot is detectable when the antenna is at 90 degrees to, and pointing at the centre of, the transmitter (allowing centimetre accurate positioning).
