Model 781 Benchtop Signal Conditioner

Model 781 Benchtop Signal Conditioner

The model 781 is a precision, two-channel bench-top signal conditioner for use with all Jewell miniature tilt sensors. Powerful electronics generate balanced AC sensor excitation for up to two tilt channels (X and Y), then amplify, rectify and filter sensor response to produce a high-level DC output signal. Output is ±8 VDC single-ended (±16 VDC differential).

Output is ±8 VDC single-ended (±16 VDC differential).

Units conveniently come with two switchable gain and filter settings (high/low; on/off) for added signal processing flexibility. The 781 also includes an amplifier for one LM35 temperature sensor and will drive tilt and temperature signals over 1000m cable lengths. All units include calibration when ordered with Jewell Instruments miniature tilt sensors. Rugged and reliable, the 781 is an ideal choice for any laboratory application.
