Honeywell FSA Series Force Sensors, Compensated / Amplified

Logo.jpg

FSA Series

The FSA Series are piezoresistive-based force sensors offering a ratiometric analog or digital output for reading force over the specified full scale force span and temperature range. They are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and nonlinearity using an on-board Application Specific Integrated Circuit (ASIC).  Direct mechanical coupling allows for easy interface with the sensor, coupling with tubing, membrane or a plunger, providing repeatable performance and a reliable mechanical interface to the application. The package also provides excellent corrosion resistance and isolation to external package stress. All products are designed and manufactured according to ISO 9001 standards.

VALUE TO CUSTOMERS
The FSA Series are designed to meet the customers’ need for a compensated, amplified force sensor that provides analog and digital outputs, a variety of force sensing ranges, and enhanced durability and accuracy. Their flexible design provides multiple standard configurations over a wide operating temperature range.  Potential applications include:

Medical
Ambulatory non-invasive pump pressure
Infusion pumps
Kidney dialysis machines
Occlusion detection

Industrial
Load and compression sensing
Variable tension control

CUSTOMER BENEFITS
Multiple force ranges allow the customer to choose the force range to maximize sensitivity and improve system resolution / performance
Overforce provides enhanced durability in applications where overforce may exist
Enhanced accuracy includes all errors due to force nonlinearity, force hysteresis, and non-repeatability
Total Error Band enhances system performance
Digital output enhances performance through reduced conversion requirements and the convenience of direct interface to microprocessors
Diagnostics functions allow the user to determine if the sensor is working correctly by detecting if the electrical paths are broken or shorted inside the sensor
Supply voltage provides customers flexibility of design within the application
