Measuring range spreading increases sensor accuracy
The strip tension and web tension control is the core competence of HAEHNE Kraftmesstechnik Company. The program includes all common types of load cells: Pillow Block Sensors for minimum and maximum forces, radial force sensors, measuring bearings and load pins, complete measurement rolls, and one-sided measuring rolls. Years of experience in providing special solutions in environnements such as high temperature, vacuum, acids, and alkalis complement the standard product program.
HAEHNE Kraftmesstechnik covers the broad field of force transducers such as force measurement bolts, load pins and load cells in the manifold forms as tension sensors in the lifting equipment as well as precise pressure force sensors for joining in the assembly. Ring force sensors, for example, in Roll Coaters allow precise control of the contact pressure rollers. Portable force gauges are designed for the measurement of nip forces in calenders.
HAEHNE provides complete measurement solutions consisting of force sensor, strain gauge amplifiers and PID Controller in particular for drives in winding applications. The new 8-channel multifunctional strain gauge amplifier module DCX was developed in close cooperation with our customers and results in particularly cost-effective solutions. Amplifiers interfaces are available in the common field bus standards: Profibus, Profinet, DeviceNet, EtherNet, EtherCAT, etc., both for field mounting as well as for DIN rail mounting, ATEX versions for hazardous areas are also available.
HAEHNE has many years of experience in the force measurement technology and in use of the Finite Element Method (FEM). Therefore, it is often possible to find lower cost-effective solutions than can be achieved with standard load cells. Examples include: adjusting the nominal force range or extending the measuring range beyond standard specification also with increased accuracy. Giving support for the risk assessment for the classification of force sensors according to the Machinery Directive, SIL3 or PLd. Preparing sensors for the use at elevated temperature to 300°C or in aggressive environments with acids and alkalis, or in high vacuum applications up 10E-7 Millibar, replacement of a standard load cell as an additive element of a machine structure by transforming your regular machine components into so-called "measurement machines elements".
Wherever tension forces must be measured and controlled in webs HAEHNE products are in use. This includes winding installations in sectors such as metal, paper, plastic, and textile. HAEHNE force measurement technology provides reliable product quality by relying on its competence and know-how of product development, manufacturing, and sales. Through our continuous implementation of knowledge and experience from many projects, we have developed into a leading solution provider for their customers. However, the benefit of the customer is our guideline. HAEHNE force sensors and the appropriate strain gauge amplifiers can be adapted by different options the specific customer situations.
