Temperature range:- -40 degree C to +180 degree C Mechanical &Electrical characteristics:- Main resonance frequency of Sensor head: > 30 kHz Up to 30kHz the sensitivity must not exceed 200 mV/g. Capacitance (of Sensor head): C = 1150 ± 200 pF Capacitance measured at frequency 1 kHz, parallel; Sensor mounted with torque 20 ± 5 Nm Due to parallel Circuit of both Sensor head and wirecapacitance only the total capacitance can bemeasured. Temperature dependence of capacitance, related to20°C room temperature for temperatures-40 °C ... + 20 °C ≤ 1,9 pF/K for temperatures +20 °C ... + 150 °C ≤ 3,3 pF/K Shunt resistor: 4,9 MΩ ± 20% after ageing: 4 – 10 MΩ( resistance between 2 signal leads) Resistor Pin for supporting sleeve > 1 MΩ Temperature-dependence of sensitivity at 9 kHz: ≤ -0,04 mV/(g*K)
