Dent Instrumentation Ltd

Contactless yarn sensors

Dent contactless yarn sensors are standard equipment for many textile machinery manufacturers worldwide and cover a wide range of textile processes – in fact wherever there is moving yarn, whether staple or spun and whatever the colour, and from 5 dtex through to heavy duty carpet yarns.

The highly accurate sensors are effective at speeds as low as 3m/min and right up to 8,000m/min, and their detection response can be adapted to each individual unit according to customer requirements.

The ‘fit and forget’ sensors are extremely durable in all operating environments, partially as a result of being encapsulated in epoxy resin. This provides protection from spin finish, oil, wax, water and any other potential contaminants, and in addition, a unique optical compensation system also contributes to ensuring very little cleaning is required.

The textile processes Dent sensors are employed in extend to filament yarns on machines for the high speed winding of POY and FDY, at speeds of 8000m/minute from 5 dtex upwards, as well as elastomeric yarns etc.

For DTY yarns, Dent provides a sensor capable of operating over the full range of speeds and yarn counts, with wrap detection on take up rollers providing early warning of dangerous wraps.

For staple fibre operations the company’s sensor range covers ring, Open End and friction spinning machines, as well as carpet yarn machines, all of which are usually low cost and very reliable.

There are an increasing number of applications for Dent sensors on winding machines too, all of which improve machine efficiency at low cost with high reliability.

A wide range of sensors is supplied for assembly winding, while specially-designed multi position sensors are are suitable for many creel applications. Sensors are also supplied for twisting machines, particularly for glass fibre operations.

The Dent Yarn Cutter, meanwhile, is suitable for cutting and clamping yarns of up to 3,000 dTex. Reliable and cost effective, it is characterised by very low consumption and a rapid reaction time, with each unit having an average lifetime of 100,000 operations.

Independence

As a company, Dent’s independence means it is able to offer impartial design advice, with a high priority placed on development by personnel who are not only highly skilled in electronics, but also experienced in textile processes.

The company’s commitment to quality is recognised by ISO9001 accreditation and every element of production is treated with care and accuracy to stringent standards.

Dent’s modern production facility has the capacity to deal with high volume orders which are increasingly being built to customer specifications. During the production process, a high level of inspection takes place at every key stage. This keeps failure rates to an extremely low level at all times.

The key reasons for the success of Dent sensors can be summarised as:

  • Proven designs
  • Co-operation with customers
  • First class production
  • Encapsulation in epoxy resin
  • Detailed inspection and testing
  • High quality at competitive prices
  • Compensation system
