bosche H08A load cell for confined installation spaces

Weidou Intelligent Technology (Shanghai) Co., Ltd. is a professional agent and distributor of German Bosche load cells and bosche miniature load cells. Some commonly used Bosche load cells are kept in stock. Customers are welcome to inquire and place orders. H08A is an ultra-compact load cell made of aluminum. It is suitable for small and very inexpensive scales with platform dimensions up to 120 x 120 mm. Due to its compact, flat design, it is particularly suitable for applications with limited installation space, such as in equipment technology. Even with long-term use, the miniature load cell provides extremely precise and reliable measurement results. As standard, H07A load cells are tested and optimized for corner load sensitivity. This means that even if the platform is loaded on only one corner, no measurement errors occur. The measuring body is made of aluminum, with encapsulated strain gauges, meeting the requirements of protection class IP65.

Scope of application

Kitchen scales, postal scales, filling machines (coffee machines, beverage filling machines), checkweighers, medical application scales.

When used as a force sensor, it can measure wire tension in the textile industry or paper web tension in the paper industry.

Construction

These load cells operate on the double bending beam principle, ensuring accurate measurement. This type of construction is insensitive to eccentrically applied forces and can withstand both compression and tension. Threaded holes for connecting the sensor or for defined force introduction facilitate assembly.

Features

Material: Aluminum

Rated load: 3 - 5 kg

Construction: Encapsulated measuring element, Protection class: IP65

Compensation for corner load error

Maximum platform size: 120 x 120 mm

Extremely low profile

Compatible with other manufacturers

Construction

The load cell is screwed into two steel or aluminum plates (max. 200 x 200 mm) via two threaded mounting surfaces on the top, front, rear, and bottom.

Only balanced outputs (nominal value and output resistance) allow multiple platform load cells to be connected in parallel.
