What makes the INSIGHT PH metal detector the leader in its class?

Posted November 24, 2011 in Industrial Metal Detectors, Metal Detection
The INSIGHT PH Metal Detector

The INSIGHT PH is the class leading metal detector for the pharmaceutical industry, excelling in all areas. Highly resistant to vibration, the Integrated Digital Search Head and sophisticated OPTIX detector management software enable the INSIGHT PH to clearly display the detailed product profile needed to achieve perfect product setups, using Lock’s unique DDS (Direct Digital Signal) vector diagram. This guarantees detection and rejection of minute metal fragments, whilst still maintaining high productivity and market leading sensitivity to all metals. These core technologies are complemented by an array of innovative features that deliver tangible benefits to the manufacturer at key stages in their manufacturing process.

What makes the INSIGHT PH so efficient?

Materials Screening

The quality of a finished product can only be guaranteed if incoming and in-process materials are
effectively screened to remove all unwanted metallic particles.

Cost Savings

Early detection of metal contamination leads to significant cost savings, as lower value contaminated materials are rejected, rather than finished products. In addition, early removal of contaminants protects downstream machinery from damage.

Vertical Fall Metal Detectors

Recommended to inspect incoming raw materials in free-falling powder form and to inspect formulations prior to the tablet press or encapsulation machine.

Superior Performance

Mounted on a new stainless steel frame, incorporating Lock’s signature gas strut stand, the ultra-
compact Integrated Digital Search Head takes care of metal detection and signal processing, resulting in extreme sensitivity to magnetic and non-magnetic metals.

Reject Options

Selections of high speed rejects are available. Each system rejects minimal product when contamination is detected and can be easily removed for cleaning without the use of tools. To accommodate high potency preparations, Wash-In-Place and Dust Tight metal detectors are fitted with dust-tight and water-tight product chutes and reject systems.

Product Quality

High speed tablet presses and encapsulating machines are designated critical control points according to HACCP principles. Contamination from broken sieves or damaged press tooling should be detected at this stage.

High Sensitivity

Extremely resistant to vibration, Lock’s Integrated Digital Search Head and sophisticated OPTIX detector management software are capable of filtering out even the most complex product
signals in order to detect and reject minute fragments of metal – particularly stainless steels.


Product integrity is protected if power fluctuates or is interrupted. “Test Prompt” software ensures adherence to quality systems.

System Design

 Lock’s signature gas strut stand is incorporated in a new stainless steel frame that offers exceptional manoeuvrability within the most compact footprint in class, making it convenient for use with all leading tablet presses and encapsulation machines.


A complete validation document is available with each metal detector, incorporating IQ, OQ, PQ, calibration and certification.

Good Manufacturing Practice (GMP)

Design and construction of the INSIGHT PH complies with FDA requirements Part 210 – Current Good Manufacturing Practice in Manufacturing, Processing, Packing or Holding of Drugs; General – and Part 211 – Current Good Manufacturing Practice for finished Pharmaceuticals – of Title 21 of the Code of Federal Regulations (CFR).


Finished in mirror-polished stainless steel, each detector is sealed to Nema 4X/IP66 to facilitate easy wash down. All parts in contact with product are fabricated from FDA approved plastic and
Stainless Steel  316.



 Every INSIGHT PH metal detector is available with SCADA capability as well as wired or wireless Ethernet connectivity. The external USB port allows all events and product presets to be downloaded onto a standard memory stick or PC to enable secure storage and distribution of quality records in PDF or other formats.

21 CFR Part 11

 Each INSIGHT PH provides data security, integrity and traceability to enable operation within a 21 CFR, Part 11 compliant environment – making full compliance with Part 11 a reality for the first time. The software implements all security access controls, electronic records and signatures as required by the FDA. Using the advanced comms options offered, the INSIGHT PH can be operated remotely or networked with other systems. Diagnostics, set-up and interrogation routines are performed by
the on-board processor and reported instantly via OPTIX.

Data Management Systems

INSIGHT PH is designed to be fully compatible with Lock’s DataChek software, thereby enabling data
monitoring and collection from all networked metal detection equipment. This provides a comprehensive and traceable central record for product, batch and validation data.
