The FS Series Force Sensor provides precise, reliable force sensing
performance in a compact commercial grade package. The sensor
features a proven sensing technology that utilizes a specialized
piezoresistive micro-machined silicon sensing element. The low power,
unamplified, non-compensated Wheatstone bridge circuit design
provides inherently stable mV outputs over the 1,500 gram force range.
The force sensor operates on the principle that the resistance of
silicon implanted piezoresistors will increase when the resistors flex
under an 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.
The sensor package design incorporates a patented modular
construction. The use of innovative elastomeric technology and
engineered molded plastics results in load capacities of 5.5 Kg over-
force. The stainless steel plunger provides excellent mechanical stability
and is adaptable to a variety of applications. Various electrical
interconnects can accept pre-wired 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.
