Description
EMT Own Welding Pig Signaler works in giving signals to operators when pigs pass the point. The connection way of it is welding. We provide a weld base for the pig signaller. It takes less than 20 minutes to set up for use, is water resistant, and is easy to use.
A Welding Pig Signaler works in detecting and signal the passage of pipeline pigs at specific points. It is connected by welding a base directly onto the pipeline, ensuring a secure and stable attachment. This setup is good for its durability and reliability in various environmental conditions. The signaler is water-resistant and designed for easy installation, typically taking less than 20 minutes to set up. Its user-friendly design allows operators to quickly receive alerts, ensuring efficient monitoring and maintenance of pipeline systems. This makes it an essential tool in industries like oil and gas, where timely pig detection is crucial for pipeline integrity and performance.

Introduction of EMT Own Welding Pig Signaler
The EMT Own Welding Pig Signaler is a mechanical contact indicator mount on the pipe. When any kind of pig passes through, it can trigger the mechanical ram. And then it will transmit the passage of the pig through the mechanical structure. The signaler indicates signals when passing through the pig in both positive and negative directions.
Main use
The signaler usually sits at the end and the beginning of the cylinder to indicate completion of the serve;
It is installed at the front end of the receiving barrel to indicate whether the pig enters the receiving barrel;
Installed on the long haul line to monitor pig passage in stages.
Peculiarity
Suitable for electrical explosion-proof occasions.
Install and disassemble with pressure.
