The sensor features a proven sensing technology that utilizes a specialized piezoresistive micro-machined silicon sensing element. The low power, unamplified, noncompensated Wheatstone bridge circuit design provides inherently stable mV outputs over the force range. Force sensors operate on the principle that the resistance of silicon implanted piezoresistors will increase when the resistors flex under any applied force. The sensor concentrates force from the application, through the stainless steel plunger, directly to the silicon sensing element. The amount of resistance changes in proportion to the amount of force being applied. This change in circuit resistance results in a corresponding mV output level. APPLYING FORCE Evaluation of the sensor is to be performed using deadweight or compliant force. Application of a rigid, immobile force will result in output drift (decrease) as elastomeric seals relax. Off-center plunger loading has minimal effect on sensor performance and maintains operation within design specifications. ELECTRICAL CONNECTIONS The sensor package design incorporates a patented modular construction. The use of innovative elastomeric technology and engineered molded plastics results in load capacities of 4.5 Kg over-force. The stainless steel plunger provides excellent mechanical stability and is adaptable to a variety of applications. Various electrical interconnects can accept prewired connectors, printed circuit board mounting, and surface mounting. The unique sensor design also provides a variety of mounting options including mounting brackets, as well as application specific mounting requirements. TYPICAL APPLICATIONS 1. Medical infusion pumps 2. Kidney dialysis machines 3. Load and compression sensing 4. Variable tension control 5. Robotic end-effectors 6. Wire bonder equipment FS SERIES CIRCUIT NOTES 1. Circled numbers refer to Sensor Terminals (interface pins). Pin 1 J Vs (+) Pin 2 J Output, (+) Pin 3 J Ground, (−) Pin 4 J Output, (−) 2. The force sensor may be powered by voltage or current. Maximum supply voltage is not to exceed 12 volts. Maximum supply current is not to exceed 1.6 mA. Power is applied across Pin 1 and Pin 3. 3. The sensor output should be measured as a differential voltage across Pin 2 and Pin 4 (Vo J V2 − V4). The output is ratiometric to the supply voltage. Shifts in supply voltage will cause shifts in output. Neither Pin 2 nor Pin 4 should be tied to ground or voltage supply.

Care should be taken not to obstruct the vent hole in the bottom of the housing. Improper venting may result in unstable output. 1 High ESD resistance 10 KV 1 Available signal conditioning 1 Optional terminal configurations Force Sensors FSG and FSL Series FS Series MOUNTING DIMENSIONS (for reference only) FSG15N1A ACCESSORY (FSG Sensor only) PC-15132 Plastic Mounting Bracket PERFORMANCE CHARACTERISTICS @ 10.0 ±0.01 VDC, 25°C Parameter Min.

Application Note #1 briefly discusses current excitation. Constant current excitation has an additional benefit of temperature measurement. When driven by a constant current source, a silicon pressure sensor’s terminal voltage will rise with increased temperature. The rise in voltage not only compensates the Span, but is also an indication of die temperature. **B.F.S.L.—Best Fit Straight Line Note: All force related specifications established using dead weight or compliant force.
