Damping affects settling time and overshoot. Standard damping will fit most applications. Double damping eliminates oscillation but settles to the final position more slowly. Some applications may require double damping to average out cyclic motion such as found in moving vehicles. Damping options can be specified when ordering.

Product Description

The T6 incremental inclinometer is a single axis, digital tilt sensor that can measure the angle of an object with respect to gravity. It uses a weight placed on one side of a wheel assembly to keep the wheel stationary with respect to gravity. An optical encoder connected to the wheel provides unlimited range and virtually no linearity errors. There is no external contact to the encoder disk. Internal magnetic damping minimizes overshoot and oscillations as the inclinometer rotates. As the housing moves relative to the encoder disk the motion is converted to TTL quadrature outputs. The quadrature outputs can be used to measure angle, speed and direction. This second generation design virtually eliminates stiction (or hysteresis) which was the primary accuracy limitation of first generation inclinometers.

The T6 inclinometer utilizes an unbreakable mylar disk, LED light source, metal shaft, and high quality ball bearings.

The T6 inclinometer is our high resolution tilt sensor and is available in several different resolutions. It is available with or without an index. The connector is polarized and has either 5 pins for single ended signals or 10 pins for differential signals. The connector is also latched providing a secure connection. The T6 operates from a single +5VDC supply.

The differential version uses a line driver (26C31) that can source and sink 20mA at TTL levels. The recommended receiver is industry standard 26C32. Maximum noise immunity is achieved when the differential signal is terminated with a 110 ohm resistor. Adding a .0047 uF capacitor in series with the termination resistor reduces power consumption by effectively removing the termination while the signal is static.

Typical applications include heavy construction equipment, dredging machinery, mining equipment, solar tracking and warehouse automation.
