0703-0703-99 Single Axis Narrow Angle Null Indicating Electrolytic Tilt Sensor DATA SHEET • Linear Range • Angle Range • Resolution • Null Repeat Description The 0703-0703-99 TrueTilt™ Sensor uses patented technology and construction to provide an accurate and robust narrow angle sensor at an attractive price. The precision-machined parts provide excellent sensor-to-sensor repeatability and reliability. Features include highly sensitive output, exceptional time and temperature stability, and superior roll axis properties. Unparalleled performance and features compared to any other commercially available product! +/-0.25° readability to ±2° 1 arc second < 5-arc seconds » Construction Laser Instruments and Transits » Aircraft Avionics » Geophysical and Structural Monitoring » Machine Tool/ Platform Leveling » Medical Positioning and Monitoring Operating Specifications Physical Dimensions Overall length...1.600" (40.6mm) Description of Test Values Tests were conducted by exciting the outer electrodes of the sensor in a single axis mode using the Fredericks Universal signal conditioner. Output curve and linearity specifications are shown above. Information on electrolytic tilt sensor signal conditioning is available on the Fredericks web site at www.frederickscom.com. Fredericks signal conditioner Signal in Excitation out (dual axis) Excitation out (single axis) Excitation out (dual axis) Excitation out (single axis) Caution!-Ensure that all test and operating circuits are entirely free of direct current. Direct current will cause level damage and/or instability. Note!-The housing (center pin) is the active output signal. The unit must be electrically isolated. Tests were conducted by exciting the left and right electrodes with an AC signal of 400 Hz and an rms voltage to produce the maximum current at null as per operating specifications. Output readings are taken between the center electrode and the center of the balanced resistors R1 and R2. Tests were conducted at a temperature of +25° C. See sensor test circuitry in figure 3. Output curve is shown in figure 1.
