We translated a set of high-level market requirements into a suite of new products that would serve the certified and uncertified gas detection markets. The new product line utilised economies of scale, enabling many new products by taking advantage of modular elements, including in software, electronics and mechanical components.

A further requirement was to ensure that the products were developed in accordance with a product lifecycle management standard, specifically IEC61508.

Zellweger’s revamped product line-up offered many new and innovative features, including improved user interface, hot-swappable sensors, high-integrity field-bus communications, as well as certification to a range of internationally recognised standards.

TTP has since developed other products requiring hazardous area approval, including portable gas detectors and gas distribution equipment.
