bosche H07A miniature load cell for tight installation spaces

Weidou Intelligent Technology (Shanghai) Co., Ltd. is a professional agent selling German Bosche load cells and bosche miniature load cells. Stock is available for some commonly used Bosche load cells. Customers are welcome to inquire and place orders. H07A is a flat miniature platform load cell with an aluminum measuring body. These very small bending beam designs are suitable for small, low-cost scales with platform dimensions up to 200 x 200 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 sensor provides extremely precise and reliable measurement results. As standard, the H07A load cell (double bending beam) is tested and optimized to improve corner load sensitivity. This means that no measurement errors occur even if the platform is loaded at only one corner. In terms of design, the platform load cell is essentially a double bending beam. The measuring body is made of aluminum, and the strain gauges are encapsulated, meeting the requirements of protection class IP65.

Scope of application

Small platform scales, postal scales, counting scales, filling machines (coffee machines, beverage filling machines) and batching scales, checkweighers, medical scales and other medical applications (level control of infusion bottles).

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

Structure

These load cells operate on the double bending beam principle, ensuring accurate measurement. This type of structure 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 of the load cell

Single-point measurement unit based on the double bending beam principle

Material: Aluminum

Rated load: 1 - 5 kg

Construction: Measuring element encapsulated, Protection class: IP65

Compensation of corner load errors

Maximum platform size: 200 x 200 mm

Low construction height

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.
