Model 84828 Slimline Signal Conditioning Card

The Model 84828 Slimline Signal Conditioning Card is a compact, analog signal conditioner for use with all Jewell Instruments miniature tilt sensors. Each 84828 card operates one 5-pin biaxial tilt sensor or one uniaxial sensor, plus one LM-35 temperature sensor, which may be installed on the circuit board. Model 84828 has one fixed gain and one RC low-pass filter, both of which can be factory-tuned to meet your requirements. This versatile and inexpensive signal conditioner has single-ended voltage output. Tilt output is measured as a ±4 VDC signal (calibrated range is ±2.5VDC). Units are also available with 0-5VDC output. The slim, low-profile design facilitates use in custom instrument packages, robotics, ROV pitch/roll control, and more.

Jewell provides factory calibration for all 84828 signal conditioning electronics when ordered with our 84053 and 84064 Ceramic, or Model 755- and 756- miniature tilt sensors.
