Explosion Protection

The strip tension and web tension control is the core competence of HAEHNE. 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.

The HAEHNE Ex-Protection Sensors are supplied as complete measuring system consisting of the following components: sensor, J-Box, safety barriers and the associated measuring amplifier. Sensor and measuring amplifier receive the order option F.

Each measuring system consists of firmly assigned components. In the case of orders containing more than one measuring system, it is prohibited to exchange individual components among themselves.

The force measurement sensors for the use in potentially explosives atmospheres are developed and manufactured in accordance with the harmonized European standards for electrical apparatus for potentially explosive atmospheres: EN 60079-0:2012 + A11:2013 (General requirements) and EN 60079-11:2012 (Intrinsic safety "i").

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 their continuous implementation of knowledge and experience from many projects, they have developed into a leading solution provider for their customers.

Haehne is the first company in web tension measurement technology to offer field bus measuring amplifiers. Today literally hundreds of systems are installed worldwide with the majority in China.
