Low cost capacitive sensors

Low cost capacitive sensors

High accuracy measurement of inclination or acceleration is available at low cost, thanks to the Seika range of capacitive sensors from Sensors UK. The NG and NB series offer inclination measurement from ±1° to 360° to a resolution of 0.001°, or acceleration measurement from DC to ±1000g.

The NG2, NG3 and NG4 are capacitive, liquid-based inclinometers with integrated sensor electronics. They provide a non-amplified, non-conditioned analogue DC output. Typical areas of application include construction, mining, vehicles, surveying equipment, aircraft, transportation and conveyor systems as well as ships.

The NB3 is a static accelerometer offered with either an analogue DC output or pulse width modulated output. Typical application areas include measuring instruments and inspection systems, vehicles, automation and safety engineering, scientific devices, medical and communications equipment as well as levelling systems.

The measurement technique employed within both ranges enables a linear relationship between the angle to be measured. They offer hysteresis-free output signals and minimal zero point drift. The sensor electronics require only minimal power and are characterised by high accuracy and long-term stability.
