Description
We are the Pig Signaller Manufacturer, Shenyang Emt Piping Technology Co., ltd. The product is a robust, non-intrusive magnetic pig signaller which detects, signals, and logs the passage of magnetic pigs at critical points along a pipeline both on land and offshore. Events are signaled as they occur via a 2.7” graphical display and high brightness LEDs positioned around the perimeter of the display.
EMT make pig detection simpler and more effective:
EMT’s range of intrusive pig signallers is detector instruments mounted on pig launchers and receiver stations to confirm the launch or arrival of a pig. They can also be mounted at any location on a pipeline and will detect the passage of all types of pipeline pigs. Our intrusive Pig Signaller uses a unique magnetic system to prevent fluid exchange blocked, therefore, it eliminates the risk of leakage from the action seal, also the trigger of the instrument is enhanced flexibility, reduces maintenance costs, and is easy to install to pipelines.

Non Insertion Electromagnetic pig ball passing indicator
The unit logs the time and date of up to 99 events. Logged events can be viewed locally on the graphical display, transmitted remotely over several optional interfaces, or downloaded using a laptop. The user can turn the unit ON and OFF as well as modify several settings using the single control button and intuitive menu system.
The unit can be quickly and easily attached to a pipeline using ratchet straps or steel banding. The unit is suitable for use on pipelines with wall thickness in excess of 40 mm. Detection speed ranges from 0.1 to greater than 10 meters per second. The window of detection is typically 0.5 m on either side of the unit. The detection capabilities vary depending on the background magnetic noise, pig speed, pipeline diameter, wall thickness, and the quality of the magnets fitted. It is recommended that pigs are fitted with rare earth magnets (neodymium iron boron) to maximize magnetic signals.
REMOTE SENSOR OPTION: The magnetic sensor can be supplied on a cable up to 10 m long for use with buried pipelines or when access is limited. The protection concept for the remote sensor is intrinsically safe ‘ia’.
POWER OPTIONS:
The unit can be powered by internal batteries or from an external +24VDC supply. Batteries can be fitted to provide backup power should the external supply fail. The unit uses 7x individual ‘D’sized cells and can be configured during manufacture for use with Alkaline cells. The unit can only be configured for use with one cell type, to change the specified cell type, the unit must be returned to Online Electronics.
ENTRY OPTIONS:
The standard unit comes with 2xM20 entries with blanking elements installed. There are an additional 4x entry positions that can be made available during manufacture. There is a generous room inside the unit to make electrical connections without the need for additional junction boxes or enclosures. Thread options are M20x1.5, M25x1.5, M32x1.5, ½” NPT, and ¾” NPT.
MATERIAL OPTIONS:
The unit can be supplied with an epoxy coated Aluminum Alloy 6082-T6, uncoated 316L Stainless Steel or uncoated 2205Duplex Stainless Steel housing. Alternative coatings can be catered for.
TEMPERATURE RANGEOPTIONS:
The ambient temperature range of the main electronics housing should not exceed -40°C to+80°C. The sensor ambient temperature should not exceed -40°C to +85°C. Higherpipeline temperatures can be accommodated using a thermally insulated remote sensor.
