Hottinger Brüel & Kjær A/S Submersible Triaxial Accelerometer 3623A1T-03

The 3623A1T-XX series is a triaxial IEPE accelerometer designed for submersible applications, featuring hermetic sealing and IP68 rating for full submersibility. It uses a 10-32 stud mount and has a titanium housing with isolated case and single crystal shear sensing element. The unit has a sensitivity of 10 mV/g, an acceleration range of ±500 Gpeak, and a frequency range of ±5% from 1.4 to 3000 Hz. It operates over a temperature range of -67 to +212 °F, with an output bias voltage of 7 to 12 VDC and supply current from 2 to 20 mA. Compliance voltage is +18 to +30 VDC, output impedance is 100 Ω, and discharge time constant is 0.4 to 1.5 seconds. Electrical isolation exceeds 100 MΩ, and transverse sensitivity is maximum 6%. It includes an accredited calibration certificate and a mounting stud.
