Pig Detectors
pig detectors and pig detection systems
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.
Used by many of the world’s largest liquid processing companies, they’re suitable for hygienic, sanitary and other liquid processes.

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. It’s available in two versions:
- Mounted (AccuTect)
- Portable (AccuTect-P)
Featuring an ultra-reliable detection signal, clear visual indication, and easy calibration, the AccuTect is 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.

How the Pig Detection System Works
The AccuTect Pig Detector contains two highly reliable sensors that provide a precise, clear and colour-coded indication of the pig’s position. When the pig is within detection range, the LED illuminates red. As the pig moves out of range, the LED changes to green.
The AccuTect Pig Detector has a default two-second output signal, which can be customised to meet specific process control requirements.
Pig detectors are usually installed close to pig launch and receive stations. The control system can use the detection signal to initiate the next stage of operation, such as starting a CIP sequence, venting the pipeline, returning the pig or resuming normal processing.
Visual Indication and Output Signal for PLCs
HPS pigs contain specially magnetised silicone cores. The detector senses the pig’s magnetic field and provides a reliable signal as the pig passes. An LED also provides the system operator with a clear, colour-coded visual indication of the pig’s presence.
In addition to providing visual confirmation, the detector signal can trigger events programmed into a PLC or pigging automation system. This enables semi-automated or fully automated control of the product recovery and pigging process.
Key Features
HPS Pig Detectors
-
Continuous Pig Detection
The HPS pig detector provides continuous and reliable detection of the pig when it is in close proximity. This minimises the potential for errors due to faulty or failed logic, eliminating the necessity for deploying multiple pig detectors in a single location.
-
Customisable Signal Length
This ensures highly reliable detection.
-
Quick-Release Mounting and Cable Connection
This ensures simple set-up and removal.
-
Clear Visual Indication of Pig Presence
LEDs provide accurate, clear and colour-coded visual indications of pig presence.
-
IP67 Rated
Ideal for hygienic (sanitary) and industrial environments.
-
Easy Calibration
Calibration is simple, quick and easy. Here’s how to calibrate the HPS AccuTect Pig Detector.
Customisable Signal Length for Reliable Detection
The HPS AccuTect™ Pig Detector offers a customisable output signal for dependable communication with process control systems. The default two-second signal can be tailored to meet specific operational requirements.
Detects Moving Pigs
A key advantage of the HPS AccuTect Pig Detector is its ability to detect the pig while it is moving. This supports accurate pig control and efficient system operation. Detection systems that require the pig to stop can contribute to increased equipment wear and reduced operational efficiency.
Simple Set-Up and Removal
The HPS AccuTect Pig Detector features a quick-release mounting system and cable connection, making it quick and straightforward to install on both new and existing equipment.
The detector attaches securely to the outside of the pipeline, with no cutting, drilling or welding required. It is robust, easy to remove when needed and can be specified for installation in hazardous areas.
Non-Intrusive Pig Detection
HPS pig detectors are non-intrusive, meaning no part of the detector comes into contact with the product. Because the detector is mounted externally, no additional welds, screws or fittings are introduced into the product-contact area.
AccuTect Pig Detectors can also be repositioned when required. With no moving parts, they provide reliable performance and a long operational life.
