Occlusion threshold
Force is measured at the mechanism; pressure inference depends on syringe area, plunger friction and assembly tolerances. Validate each supported syringe or tube family.
MT-BLC-MED / SERIES
OEM Medical Infusion & Syringe Pump Force Sensor

Series options are not a full cross-product of every dimension and capacity. Button radius, tolerances, overload and model-specific performance are confirmed on the released drawing and quotation.
Build occlusion sensing around the real pump mechanism.
Power budget
Provide excitation, bridge resistance and measurement duty cycle. Resistive bridge power is approximately V²/R and must be included in a portable device budget.
Device qualification
Agree zero drift, temperature cycling, overload, lifetime, traceability and change-control criteria. Sensor supply does not establish approval of the finished medical device.

The load path mattersLoad the convex button.
Load the convex button.
Give the cable room to move.
A compact sensor only measures correctly when the surrounding fixture supports it correctly.
Support the intended base surface
Machine a rigid, flat seat from the exact outline. Locate the sensor without squeezing the case or bypassing the sensing load path.
Keep contact on the central button
Align compression with the sensing axis. Keep the tool clear of the cover and outer case; a spherical top helps accommodate small alignment differences.
Relieve the fine shielded cable
Provide a dedicated exit channel and jacket retention. Specify flexing, bend space and a strain-relief spring or sleeve with the configuration.
