OEM Force Sensors for Pump Occlusion Detection

In a syringe pump, a first-order relationship is pressure = axial force / piston area. Plunger friction, drive friction, compliance and transient motion also contribute to the measured force. The alarm threshold must be validated with each supported syringe and operating condition.

• OEM range requests: 5, 10, 15, 20, 50 or 100 N.
• Provide mechanism preload and maximum drive force.
• For tube pumps, characterise the actual tube interface rather than applying a syringe-area formula.

Share available stack height, retention details, PCB keep-outs, bridge excitation, resistance and measurement duty cycle. A low-profile plastic or PCB force package and a machined metal load button can have very different load paths and electrical interfaces.

• Honeywell FSS 15 N is an original-product reference, not proof of a mechanically equivalent MT-BLC-MED.
• Ask for the OEM package drawing and connector/pin definition before design freeze.
• Bridge power during excitation is approximately V²/R.

Define zero stability, lot variation, thermal cycles, overtravel, lifetime and the system alarm response. Identify the serial or lot record needed for your own device quality system. No finished-device approval or medical certification is implied by a sensor enquiry.

• Review cleaning and fluid exposure separately.
• Keep revision control for package, cable and calibration settings.
• Use the calibration-record guide to define the requested deliverable.
