ASC P311A15 Industrial Piezoelectric Accelerometer
Uniaxial, analog voltage output acceleration sensor for condition monitoring and structural health monitoring applications
About the ASC P311A15 Industrial Piezoelectric Accelerometer
ASC’s Industrial accelerometers are made of piezoelectric ceramics and are usable over a wide frequency range from 0.8Hz to 15kHz. The accelerometers are IEPE (Integrated Electronics PiezoElectric) sensors that produce an output voltage proportional to the input acceleration. The sensors feature a built-in preamplifier and a charge to voltage converter that transforms the high-impedance charge output from the piezoelectric ceramic (Lead Zirconate Titanate, PZT) into a low-impedance voltage output able to drive long cables. ASC’s IEPE sensors operate on a constant-current supply and use a simple two-wire coaxial cable for power input and signal output.
Description
ASC’s IEPE Industrial accelerometers, P311A15 and P311A25, are analog voltage output sensors. These piezoelectric vibration sensors are used typically in condition monitoring and structural health monitoring applications. The sensors are based on a piezoelectric compression design, which provides high rigidity and excellent shock resistance.
ASC’s Industrial accelerometers, P311A15 and P311A25, feature a rugged stainless steel housing that is corrosion proof and chemical resistant. Types P311A15 and P311A25 operate over a wide temperature range from -55°C to +140°C. The sensors are environmentally sealed to IP68 grade and can withstand shocks up to 5000g’s. The industry standard 2-pin MIL-C-5015 type top and side exit connectors provide flexible mounting options. The sensors can be optionally fitted with an integral cable.
ASC Type P311A15 has a side exit connector and Type P311A25 has a top exit connector. The standard versions have a measuring range of ±80g (Sensitivity: 100mV/g) and a ¼“-28 UNF mounting thread. For flexibility in mounting, metric mounting studs and threads (M6/M8/M10) are available as options.
