Unirectional Flange Pig Signaler
- EMT
- Shenyang, China
- 15 days
- 200 sets/month
The unirectional flange pig signaler is divided into mechanical explosion-proof pig signaler, plug-in pig signaler and non-intrusive pig signaler.
Unirectional Flange Pig Signaler Technical Parameters:
Applicable temperature is -40 to 100 °C.
for all materials of the pipeline
the pig must have a magnetic source
Applicable to explosive gas and flammable medium
explosion-proof mark ExdIIBT6
control contact capacity: 24VDC, 3A
remote transmission wiring hole thread: 1/2NPT
Installed on the pipeline, it is mainly used to display the time after the pig is sent out and to indicate the alarm. You can check the pass of the pig at any time.

EMT Pig Signaler（Pig Passage Indicator）
EMT Pig Signaler is used to provide confirmation of the movement of pipeline pig through a pipeline. Pig Signaler is normally positioned at both the pig launching and pig receiving stations and at key points along a pipeline.
The EMT Pig Signaler offers several benefits for various applications. Here is an outline of the benefits based on the trigger types, indicator types, and mounting types:
I. Trigger Types:
Bi-directional:
Allows signaling in both directions, providing flexibility for different scenarios.
Useful for applications where the pig needs to be detected and triggered in either direction of travel.
Bi-directional Feather:
Offers a more sensitive triggering mechanism, requiring a lighter force to activate.
Ideal for situations where the pig may have low pressure or velocity but still needs to be detected.
Uni-directional:
Designed for signaling in only one direction, ensuring accurate detection in specific applications.
Suitable for situations where the pig is expected to move in a single direction, such as pipeline cleaning operations.
II. Indicator Types:
B_Manual reset flag:
Provides a visual indication when the pig triggers the signaler.
Requires manual resetting after the pig passes through, ensuring clear visibility of pig movement.
C_Manual reset flag combined with electrical switch output:
Offers both a visual flag indicator and an electrical switch output.
Allows integration with other systems or devices, enabling automated processes based on pig detection.
D_Digital display combined with electrical switch output:
Provides a digital display for real-time pig movement tracking.
Offers an electrical switch output for integration with other systems or devices.
Features of EMT Pig Signaller
l Suitable for pipe sizes from 2” upwards
l A range of design pressure from ANSI 150 # to ANSI 2500 # are available for 2 "flange connection,
The highest design pressure is 10000Psi(69MPa) for boss connection.
l The working temperature range is -20ºC to +120ºC. Special seals can be provided for operating temperatures outside this range
l Trigger mechanism does not use dynamic seals therefore both prevent leakage and ensure trigger flexibility(The boss connection, with pop-up indicator or the digital display is excluded). The flag is interactivity with the trigger mechanism, therefore, the flexibility of trigger mechanism can be checked online.
l The requirement about adjusting Insert depth can also be met.
l Easy to operate, Proven durability, minimal maintenance required.
Suitable for all types of pipeline pigs such as Foam Pig, metal Bodied Pigs, Spheres, Intelligent Detection Pig
