Modular sensors are designed to meet a wide range of application needs for infusion pump manufacturers. When selecting force and pressure sensors for these devices, reliability, sensitivity, and miniaturization are key considerations. As infusion pumps evolve from large, stationary units to compact, portable, and even implantable systems, designers need flexible sensor platforms that support diverse design concepts.
To reduce overall costs, enhance reliability, and speed up time to market, it’s essential to choose pressure sensors with full compensation, amplification, and calibration features. These capabilities ensure accurate performance across different operating conditions.

The platform supports custom calibration and provides multiple output, power, stress, mounting, and packaging options, offering maximum flexibility in system design.
Force and pressure sensors must be highly reliable and sensitive to ensure precise medication delivery. A pump-mounted pressure sensor helps monitor and control fluid flow, while an external force sensor measures the force in the drug delivery line, detects blockages, and triggers alarms when no medication is available. These sensors are designed to be modular, allowing one model to address multiple application requirements.
The force sensor platform also shares the same sensing element as the pressure sensor, enabling manufacturers to verify both sensors’ performance and quickly adjust measurements. This ensures faster response to rising demand and sample requests.
These force sensors come in various package types, allowing for different connections between the sensor and the infusion pump tubing. They use piezoresistive technology in a compact form factor, delivering accurate and reliable force detection. Their high sensitivity allows early detection of blockages, improving patient safety.
For infusion pumps and dialysis applications, different package types are necessary to maximize flexibility. For example, wing-shaped pins on force sensors allow medical device manufacturers to switch from through-hole to surface-mount designs, supporting high-volume production. Surface mount technology also eliminates manual soldering, making the manufacturing process more efficient.
Smaller sensor sizes enable integration into compact infusion pumps, enhancing patient comfort and safety. Additionally, low power consumption further improves usability and reliability in clinical settings.
