OnlinE Magsig - Model 4001D -Non-Intrusive Pipeline Pig Signallers
The OnlinE 4001D MAGSIG® is a fully ATEX and IECEx certified, 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 signalled as they occur via a 2.7” graphical display and high brightness LEDs positioned around the perimeter of the display.
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.
Product Options
- Can be used as:Non-Intrusive Pig Signallers, Pig Signallers
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 40mm. Detection speed ranges from 0.01 to 20 metres per second. Window of detection is typically 0.5m 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 magnets fitted. It is recommended that pigs are fitted with rare earth magnets (neodymium iron boron) to maximise magnetic signal.
REMOTE SENSOR OPTION:
The magnetic sensor can be supplied on a cable up to 10m 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 from 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 (DURACELL ID1300) OR Lithium (SAFT LS33600) OR NiMH rechargeable (ANSMANN MaxE D) 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 which can be made available during manufacture. There is 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, 1⁄2” NPT, and 3⁄4” NPT.
MATERIAL OPTIONS:
The unit can be supplied with an epoxy coated Aluminium Alloy 6082-T6, uncoated 316L Stainless Steel or uncoated 2205 Duplex Stainless Steel housing. Alternative coatings can be catered for.
TEMPERATURE RANGE OPTIONS:
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. Ambient temperatures of -50°C can be accommodated by installing a heater within the electronics housing. Higher pipeline temperatures can be accommodated using a thermally insulated remote sensor.
