Torsion pole spring tiltmeter is a mini-tiltmeter that is used to measure very small floor tilt and it can be widely applied to not only engineer construction in the fields of railroad

water and electricity

traffic

architecture and city planning etc

but also the background measurement of floor tilt in some scientific experiments.The capacitance gaps on both sides of mechanical oscillator in the torsion pole spring tiltmeter are difficult to be the wholly same because of the machining error

so the variation of ambience temperature and its grads will lead to the inconsistent variation of capacitances on both sides and the output of capacitance transducer circuit will also change.The effect of the ambience temperature and its grads to torsion pole spring tiltmeter is studied theoretically and experimentally.The experimental result shows that the ambience temperature and its grads can influence rather obviously the measurement precision of the floor tilt with torsion pole spring tiltmeter.And therefore

it is significant for precise measurement of the floor tilt to study response to the ambience temperature and its grads.
