  • Page 6: Converting Voltage Readings To Tilt Angles And Temperatures

    Converting Voltage Readings to Tilt Angles and Temperatures The tiltmeter voltage outputs are quickly converted to tilt angles as follows: Multiply the voltage reading by the scale factor in Appendix A. For example, if the scale factor is 0.600 degree/Volt and the voltage reading is +2.000 Volts, then the tilt angle is +1.200 degrees from sensor null.
