Product Details
M2428 is a low-cost load cell (balance, scale, weighing device) to measure weights or forces in the range of 100kg (~1’000N) to 100’000kg (~1’000’000N).
Mostec specializes in developing and producing customer specific cells for vessels and a variety of other, more general industrial use; as well as various standard load cells. All Mostec cells are manufactured in-house. Our way of construction allows production of small batches.
A load cell consists of a hydraulic cylinder, a ceramic strain gage sensor or a strain gage bonded to a spring element with integrated electronics to convert the force or weight to a 4…20mA signal. There is no need to use external, sensitive strain gage amplifiers or signal conditioning devices. A cell connects directly to any 2-wire sensor input of process control computers or other control equipment and displays.
All cells are available in various, customer specified materials, they are waterproof and need an ordinary 3-pole, 16mm valve plug or open cable ends.

Shear beam load cells or other spring elements equipped with metallic strain gages are used in high accuracy and long term stability applications. Assembling strain gages to the spring element is manual work. Hydraulic systems, basically a cylinder with piston and sensing element, are used when good stability, low price and high quantities are required. Friction on surfaces and O-rings limit the accuracy. However, it’s not possible to achieve the same, good data as with spring elements and strain gages. |

Load cell type M2428-14
Code: Product Details The M2428-14 is a low-cost load cell to measure weights or forces in the range of 25kg (~250N) to 30'000kg (~300'000N). The bending beam consists of a strain gage sensor with integrated electronics to convert the force or weight to a 4…20mA signal. There is no need to use external, sensitive strain gage amplifiers or signal conditioning devices. A cell connects directly to any 2-wire sensor input of process control computers or other control equipment and displays. The bending beam confirms the protected class IP67 an delivered with open cable ends. Any range within the measuring range can be programmed. E.g. 45kg to 420kg = 4 to 20mA within a calibrated range of 0 to 500kg.
