Two major force (load) detecting sensors are the strain gauge (mainly used for static loads) and the piezoelectric sensor (mainly used for dynamic loads). Fuji Ceramics force sensors are piezoelectric sensors. They have prior characteristics that are not available in strain gauges. |

  Compact and high sensitivity: 4mm in thickness; measuring range up to 22.24 kN (= 2000 kgf) Wide effective range: linear output from low to high loads Mechanical strength: amount of strain less than 6.4 µm (calculated value for C1K20 under 20 kN); resonant frequency higher than 20 kHz High durability: simple and reliable structure using a piezoelectric element Preamplifier incorporated: expensive charge amplifier unnecessary |

·Sensitivity Output per N(newton). Linear outputs are obtained for up to the maximum usable load. ·Maximum usable load (Measurement range ) Maximum load that can be measured by a force sensor in normal operating conditions. ·Allowable load Should a load exceeding the maximum usable load be applied to a sensor, this sensor does not deteriorate in characteristics. Sensors may not be used continuously under the allowable load. ·Discharge Time Constant (DTC ) A piezoelectric force sensor is characterized by self-discharge. The output voltage presents an exponential curve that changes at a proportional rate for a given length of time. The discharge time constant is the period of time during which the output voltage drops to 36% of the initial value. |
