Web Tension
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 environments such as high temperature, vacuum, acids, and alkalis complement the standard product program.
Force Measurement
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.
Amplifiers and Controllers
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, etc., both for field mounting as well as for DIN rail mounting, ATEX versions for hazardous areas are also available.
Special Solutions in Force Measurement Technologies
Do you have a special requirement for force measurement technology that cannot be covered with a standard sensor?
HAEHNE has specialized in force sensors according to specifications and has developed a corresponding modular system. In addition to the design of “sensors according to drawings”, HAEHNE also offers an expanded option system that can be used on almost all standard sensors. For example: Adjustment of the nominal force or measuring range spread also with increased accuracy, SIL2 or PLd explanations for HAEHNE products, use at elevated temperatures up to 300 ° C or in aggressive environments with alkalis and acids, applications in high vacuum up to 10-7 millibars, replacement of a standard force sensor as an additive element of a machine construction by the formation of system parts to so-called "measuring machine elements".
New force measuring block as direct replacement for Philips PR 9951
The new pillow block bearing was developed as a 100% compatible sensor to the earlier Philips PR-9951 series.
The external dimensions and mounting holes of the BZHPR9951 are 100% compatible with the earlier Philips PR-9951 series. The quick and easy installation is carried out as usual using 4 screws.
Force measuring roller for stranding machines
The RMR3 series force measuring rollers have been specially developed for measuring wire tension in cage and tubular stranding machines. Applications in stranding systems require precise measurement and control of the individual wires. With the RMR3 series, HAEHNE comes into play and relies on a portfolio with outstanding features that can make the difference in the daily production process.
Precise web tension measurement in printing presses
Applications in flexo or gravure printing, for example, require precise control of the material to be printed, which often has very different properties. This is where HAEHNE comes into play. With the RCA series HAEHNE demonstrates outstanding features throughout the portfolio that can make all the differences in the daily production process.
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.
