pig detectors and pig detection systems
For Hygienic (Sanitary) and Other Liquid Processes
The HPS AccuTect pig detector (or pig detection system) is an advanced, intelligent pig detection device that determines the presence of an HPS pig when it’s in close proximity.

reliable and accurate pig detection
An essential component of pigging systems, pig detectors are usually located close to launch and receive stations, enabling highly efficient, safe and reliable operation – whether automated, semi-automated or manual.
HPS have designed the AccuTect pig detector with system integration and control in mind. Featuring an ultra-reliable detection signal, clear visual indication, and easy calibration, it’s ideal for hygienic (sanitary) and industrial environments.
Offering high levels of efficiency, reliability and performance, the AccuTect pig detector is used by some of the world’s largest liquid processing companies.

The AccuTect pig detectors are a big improvement! We are very happy with them (and so is our partner who does the programming for the automation).
How the pig detection system works
The AccuTect pig detector comprises of two ultra-reliable sensors which provide accurate, clear and colour-coded visual indication of pig position. When the pig is in close range, the LED lights on the pig detector will illuminate red to indicate the position of the pig. When the pig goes out of range, the LED lights will change to green. Note: The AccuTect Pig Detector has a two-second output signal by default, however, this can be customised to the required output length.
Pig detectors are usually fitted close to the pig launchers and pig receivers, and the control system will use the signal to initiate the next phase of the operation (for example, starting a CIP sequence, venting the line, using the receiver to return the pig, returning to normal processing and so on).
Visual Indication with Output Signal for PLC
HPS pigs have special magnetized silicone cores. The pig detectors sense the pigs magnetic field, which provides an ultra-reliable signal as the pig passes. When the device detects the presence of a pig, it also lights an LED. This provides an accurate, clear and colour-coded visual indication to the system operator of the pig’s presence.
One of the key benefits of HPS systems is that, as well as a visual indication, the signal can also be used to determine events programmed into a PLC or pigging automation software. This enables semi or full automation of the product recovery and pigging process.
Customisable Signal Length Provides Highly Reliable Detection
With customisable signal length, the HPS AccuTect pig detector is extremely reliable. Please note, the Pig Detector has a two-second output signal by default, but this can be customised to the required output length.
Detects Moving Pigs
A major technological advantage of the HPS pig detector over other pig detection systems is that it detects the pig when it is moving. This enables extremely accurate and precise control of the pig. Other systems need to have the pig at a stationary position (i.e. stopped) to sense it, which causes excessive wear on the equipment and low-efficiency operation.
SIMPLE SET-UP AND REMOVAL
The HPS AccuTect pig detector has a quick-release mounting and cable connection. This makes them quick and easy to install on both existing and new equipment.
They conveniently yet firmly attach onto the outside of the pipe. There’s no cutting, drilling, welding or so on required which ensures simple set-up and removal. They are also extremely safe and robust and can be installed in hazardous areas.
Non-Intrusive Pig Detectors
Because HPS pig detectors are non-intrusive, no part of the pig detector comes in to contact with the product, so there’s no risk of contamination. In addition, because they are clamped externally, there’s also no danger of contamination from poor welds, poorly fitting screws, fittings and so on. As well as being easy to install, they are also easy to move if required. Because they have no moving parts, they have a long life expectancy and are extremely reliable.
