About us

Dent has a heritage of commitment to total quality assurance in everything it does for its customers.

We have total focus on yarn sensor design and manufacture. This has made us the world leader in a technology that is now indispensable to textile manufacture worldwide.

The patent for the world’s first contactless yarn sensor was granted to Company founder Geoffrey Dent in the 1960s.

Yarn sensors are integral to production processes. Dent’s technical team works closely with textile machinery manufacturers. This has resulted in a deep-rooted culture of innovation, improvement and partnership.

Our drive for total quality will never stop. Sensors are inspected and tested multiple times before shipping. This helps ensure that once fitted, a Dent sensor should perform faultlessly throughout a working life. In practice, this proves to be around ten years, depending on the operating conditions.

The legacy and the future

Dent’s range of sensors provided the company’s solid foundations. These ‘legacy’ sensors became the textile industry’s standardised products.

Today, the lion’s share of Dent’s R&D and manufacturing is producing custom sensors for OEM textile machinery manufactures.

The company continues to maintain high standards of design and manufacturing excellence.

Never shy to invest, the company holds a unique position at the fore of this technology. We continue to pursue improved advantages for our customers’ products. In turn, they can offer better efficiencies and benefits to their customers. Similarly, we continue to research emerging applications for our technologies and expertise, to the benefit of our customers.

The New Vision: 8 guiding principles

Dent Instrumentation has committed to a new Vision statement and has initiated a new, dynamic business culture referred to as ‘Delivering The Vision’, our Guiding Principles for the Future.

This is the aspiration to seek additional business opportunities beyond Dent’s core market, and adopting the mind-set to:

  • Relentlessly innovate
  • Use fewer resources
  • Minimise Dent’s environmental footprint
Our Vision

The Guiding Principles are the foundation for the new culture. They set a framework of standards and conduct that we all choose to operate within and to which we are all accountable.

These Guiding Principles are:
1. Integrity – have the courage to always act with integrity, it is the foundation for trust and mutually beneficial working relationships.
2. Stewardship & Compliance – put safety first: stop, think and ask; act with proper regard for the rights of others; drive environmental excellence and comply with all laws and regulations.
3. Principled Entrepreneurship™ – pursue opportunities, relationships and transactions in which Dent succeeds by benefitting others; make Dent the preferred partner of customers and suppliers.
4. Transformation– continually transform yourself and the company; deliver success at a greater rate than current and future competitors.
5. Knowledge – acquire and use the best knowledge from sources that will enable improved performance; share knowledge proactively; respectfully provide and solicit constructive challenge.
6. Humility – be humble, intellectually honest and deal with reality; understand yourself as you really are and accept others as they really are, not how we wish them to be.
7. Respect – treat everyone with honesty, dignity and sensitivity; embrace different perspectives, experiences, aptitudes, knowledge and skills; embrace diversity.
8. Self-Actualisation – be a lifelong learner and realise your potential, attain greater fulfilment, better deal with reality, freely face the unknown, creatively solve problems and help others succeed.

The diagram below illustrates the Guiding Principles and visually depicts their order, which is significant. The top 3 are the necessary, but of themselves, insufficient requirements for a business to survive into the medium term. Integrity always comes first. Transformation is the necessary additional requirement for a business to prosper into the long term. The remaining 4 are the necessary behavioural requirements within a successful, progressive organisation. These principles guide and empower colleagues to contribute as fully as they are able and to grow with the business.

Guiding Principles

Delivering The Vision strives to create and nurture an environment where people excel, individually and collectively, transforming themselves and the business. The vision is for Dent to be more dynamic and creative, more efficient and effective, more proactive in utilising skills, expertise and relationships to satisfy consumers’ unmet needs by continuously developing new products and capabilities that mutually benefit Dent Instrumentation and its business partners.
