Welcome to KaiTuo Precise Instrument Co., Ltd
KT produces the JB4 for industrial grade applications including: automotive test instrumentation, braking system deceleration, bridge and building sway and tilt monitoring, industrial and robotic control, land vehicle navigation, subway and high-speed train ride comfort control, and offshore drilling platform motion monitoring.
The integral electronics develops an acceleration-proportional output current providing both static and dynamic acceleration measurement. By use of customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage. Especial JB4-03, it s’ operating Temperature Range is -55~180oC.
Features:
1. Tactical navigation grade performance
2. Analog output
3. Field-adjusting range
4. Widely operating Temperature Range
