Info

The instrument's tilt sensors are also electronic, with a resolution of 1 arcsecond. The outputs from the sensors are displayed on the instrument's frontpanel and also transmitted to the data acquisition system where they aredisplayed and stored. If the instrument is operated on an unstable base,real-time corrections for tilt errors can be automatically made over a range of±400 arc seconds.Protection from ambient temperature changes is provided by locating thequartz elastic system, the analog to digital converter, sensitive electroniccomponents and the tilt sensors inside a high-stability, two stage,thermostatically controlled environment. There is no mechanical temperaturecompensation. External temperature changes are reduced by a factor of over104 and small residual effects are corrected in software using the output of asensor located in close thermal contact with the main spring.The operating range of the thermostat in the standard instrument is -40°C to+45°C. However, since there is no critical operating point for the sensor, theupper operating temperature can be set at a lower or higher value (optional-45°C).The entire gravity sensing mechanism is enclosed in a vacuum chamber.Since there are no mechanical feed-throughs, excellent isolation fromvariations in atmospheric pressure is obtained. This extremely stableoperating environment for the quartz elastic system allows the long-term driftof the sensor to be accurately predicted, and real-time software correctionreduces it to less than 0.02 mGals/day.The sensor design is mechanically very simple. The fine balancing requiredto obtain astatisation is not needed, as the displacement transducer hassufficient resolution (0.02nm) to detect the beam position of a non-astatisedsystem, and electronic filtering reduces the effect of seismic noise.The mechanisms, micrometer screws, gearboxes and mechanicalfeed-throughs associated with mechanical feedback systems have beenreplaced by a voltage applied to the same plates which form the displacementtransducer. The temperature control is also accurate enough for the sensor tooperate without mechanical compensation.B-2CG-5 Manual - part # 867700 Revision 2
