Product Line
Micro Load Cells & Force Sensors
Full range of advanced thin film load cells — compression and tension, beam and button styles. Autoclavable options available. Capacities from sub-gram to 5,000 kg. SMD's proprietary thin-film process gives unsurpassed long-term stability in medical, semiconductor, and industrial OEM environments.
Featured Model
Model S251
Beam Load Cell — High Range Platform
The S251 uses SMD's proprietary thin-film strain gauge process — metal resistors sputtered directly onto a stainless steel flexure with no adhesive layer. The result is outstanding long-term zero stability, low hysteresis, and low power consumption. Available in 30 kg and 50 kg platform configurations with built-in overload protection.
