Electrical Information
The 122 transducer requires an external power source capable of supplying ±15 VDC, ±5%, at
35 mA minimum. Noise and ripple should be less than 20 mV p-p. Any readout device may be
used which has input capabilities of 0 to 10 VDC and impedance greater than 10k ohms.
Grounding
Note
The ground of any external power supply and readout should be the same
as the sensor ground (chassis ground), to minimize any possible ground
loops which can affect the performance and stability of the system.
