Model 84800 Single-Channel Signal Conditioning Card

The Model 84800 is a single-channel, compact, high-performance signal conditioner for use with all Jewell Instruments miniature tilt sensors. Each 84800 conditioning card will provide excitation and signal conditioning for any electrolytic tilt sensor and for one LM-35 temperature sensor. Output is a stable ±5 DC voltage (±10 VDC differential). Units also include a built-in 1.75 sec low-pass Butterworth filter for superior noise rejection (specify custom filter times on order), and the square form factor allows for easy packaging in OEM and end-user assemblies. The Model 84800 will drive signals over cable lengths of 300m. Distances between card and tilt sensor can be up to 100m. Use the 84800 signal conditioning card for peak performance with any of our 755 series, 756 Series, or Ceramic Miniature Tilt Sensors.
