Glass Mid-Range 0737-0101-99 - 1

DATA SHEET Operating Specifications Description The 0737-0101-99 Sensor has been used successfully in applications that demand ultra high accuracy, excellent null repeatability, mid-range angle measurement and a linear output. Long term stability over its angle and temperature range is a distinctive characteristic of this sensor. The hermetic glass to metal construction and platinum electrodes guarantee a long operating life and stable operating characteristics. Angle Range Resolution Null Repeat Applications Include » » » » » Geophysical Monitoring Construction Laser Instruments and Transits Aircraft Avionics Machine Tool Leveling Medical Positioning and Monitoring Measured left to right electrode, Impedance of the electrode may be changed to limit null current. 2 Viscosity of the electrolyte may be modified to meet individual requirements for time constant or vibration. OUTPUT SENSITIVITY Figure 1 Physical Dimensions 1.13” max (28.70mm) 0.320”max (8.13mm) 15.0” max (381mm) custom lead length available Sensor Test Circuitry 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.
