Force Sensors
FSA Series, Compensated/Amplified
DESCRIPTION
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.
DIFFERENTIATION
• 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 non-
linearity, 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
