Piezoelectric Accelerometers

Description ： Accelerometers is a case-mounted seismic sensor in general purpose. It is a piezoelectric sensor fixed in hot molded body. This structure makes the accelerometers extremely durable, well-suited for harsh industrial environments. Two-pin screw-type connector on top of sensor allows easy disassembly of the sensor cable. Bottom of the sensor has a 1/4-28UNF threaded female connector, allowing a variety of installation methods. Technical Specifications:  Sensitivity：10.2mV/m/s2 (100mV / g) ± 12%, at 80Hz  Frequency response：10 to 1kHz ± 10%; reference to 80Hz  Acceleration range:：245m/s2 (25g) peak, at +25 ℃ when used in the entire temperature range of 176m/s2 (18g) peak  Amplitude Linearity:In 9.8m/s2 to 98m/s2 (1g to 10g) peak Within the range of 2%  Transverse sensitivity:At 80Hz is less than 5% of sensitivity  Mounted resonant frequency: Greater than 5kHz  Polarity: When the direction of movement from the mounting stud to the top connector, the output signal is positive  Broadband Electrical Noise：Less than 0.147m/s2 (0.015g) rms  Electrical Isolation (Pin to Case)：600Vrms  Housing Material：316 series stainless steel  Operating and Storage Temperature：-40 ℃ to +85 ℃  Relative humidity：100% relative humidity, non-flooding  Shock Survivability：When a fall from 3 feet to compete polyethylene based film covering on the floor, the sensitivity variation is less than 5%
