## 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. 

- Stable interface plunger 

- Internal diagnostic functions available 

- REACH and RoHS compliant 

## POTENTIAL APPLICATIONS 

Medical: 

- Ambulatory non-invasive pump pressure 

- Infusion pumps 

- Kidney dialysis machines 

- Occlusion detection 

Industrial: 

- Load and compression sensing 

## PORTFOLIO 

The FSA Series joins the FSG Series, FSS Series, FSS-SMT Series, TBF Series, and 1865 Series. 

## 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

1Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected. 

2Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage. 

3The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure. 

4Operating temperature range: The temperature range over which the sensor will produce an output proportional to force. 

5Compensated temperature range: The temperature range over which the sensor will produce an output proportional to force within the specified performance limits. 

6Accuracy: 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. 

7Full Scale Span (FSS): The algebraic difference between the output voltage at full scale force and the output at zero force. 

8Total 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. 

9Long-term stability after 1000 hr of operation at 25°C [77°F].
