FSA Series, Compensated/Amplified
Datasheet
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 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

Storage temperature range
Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.
Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating
voltage.
3
The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical
failure.
4
Operating temperature range: The temperature range over which the sensor will produce an output proportional to force.
5
Compensated temperature range: The temperature range over which the sensor will produce an output proportional to force within
the specified performance limits.
6
Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the force range
at 25°C [77°F]. Includes all errors due to force non-linearity, force hysteresis, and non-repeatability.
7
Full Scale Span (FSS): The algebraic difference between the output voltage at full scale force and the output at zero force.
8
Total Error Band (TEB): Combined error from calibration, accuracy and temperature effects over the compensated temperature
range at 5.0 V from 15 %FSS to 95 %FSS.
9
Long-term stability after 1000 hr of operation at 25°C [77°F].
