In each installation requirements of power, insulation to motion and temperature, and air intake and instrument operation needed specific consideration. Power was usually supplied by a 60-cycle, 110-V gasoline generator except in the aircraft where the 24-V aircraft battery was used. Venturi effects while sampling in motion were controlled by attaching an air baffle at the intake. Temperature stability was achieved by the use of insulation material, and the equipment was carefully mounted on an independent spring suspension to protect it from vibrations. 

By flexible bolts or rubber springs on foundation. By guiding leaf springs on counter-vibrating frame. Suspension mounting possible. 

Modem short-period seismometers and geophones are passive inertial sensors which consist of a pendulum with a velocity transducer with sensitivity G in V-s/m mounted so as to measure the relative velocity xt of a proof mass M and frame of the sensor, as shown in Fig. 3. The spring constant of the mainspring and suspension combined K and the viscous damping B determine the transfer function of the pendulum, required to relate the output voltage Vg to the input motion of the frame, x .
