Description

The FSS Series Force Sensor provides precise, reliable force sensing performance in a compact, commercial-grade package at a cost effective price. The sensor features a proven sensing technology that uses a specialized piezoresistive, micromachined silicon sensing element. The low power, unamplified, uncompensated 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 ball, 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 change.

The sensor package design incorporates patented modular construction. The use of innovative elastomeric technology and engineered molded plastics results in overforce capacities of up to three times the rated force. The stainless steel ball provides excellent mechanical stability and is adaptable to a variety of applications.

The FSS Series Sensor delivered 20 million operations in Mean Cycles to Failure (MCTF) reliability testing at 50°C [122°F]. This test determines the number of possible sensor operations at full scale until failure.

Features

  • RoHS-compliant materials meet Directive 2002/95/EC allows use in industries requiring regulation compliance
  • Low deflection (approx. 30 µm typical at full scale) helps reduce measurement error
  • Direct mechanical coupling of the actuation ball to the sense element reduces coupling errors and keeps mechanical hysteresis to a minimum
  • Product rating of 20 million MCTF at 25 °C [77 °F], subject to application variation, provides for consistent output over time and reduces repairs or replacements
  • Small size minimizes space on the printed circuit board (PCB)
  • Provides enhanced sensitivity without compromising signal integrity, resulting in low system noise and reducing measurement errors
  • Electrically ratiometric output accommodates supply voltage variations, leading to low ratiometricity error
  • Low voltage supply allows for use in many battery powered applications
  • High resistance to electrostatic discharge (ESD) meets ESD Sensitivity Classification Level 3B (8 KV), reducing special handling during assembly
  • Sensor output has low sensitivity to many mounting stresses
