-====== Inclinometer ====== 
  
-===== Summary ===== 
-==== Introduction ==== 
-**Inclinometers**,​ alternatively known as **gravitational** or **tilt sensors**, measure an angle from the direction of Earth'​s center of gravity. ​ 
-The words "tilt sensor"​ are often used to describe a tranducer of tilt specifically using gravity as a reference (Puccio 2004). 
- 
-==== Examples ==== 
- 
-Mercury switches, used for instance in Michel Waisvisz'​s [[http://​www.youtube.com/​watch?​v=RJ4zliNA7eI|"​The Hands"​]] (Waisvisz, 1985), are examples of //on-off// tilt sensors. One commercial example is the [[http://​infusionsystems.com/​catalog/​product_info.php/​cPath/​24/​products_id/​75|TiltOn]],​ a mercury switch-based single axis inclination sensor supplied by [[http://​www.infusionsystems.com/​|Infusion Systems]]. 
- 
-Examples of sensors measuring continuous inclination include //​electrolytic tilt sensors//. These sensors typically consist of an electrolytic fluid ([[http://​en.wikipedia.org/​wiki/​Electrolyte|electrolyte]]) partially filling a tube with three electrodes (one-axis sensors) or five electrodes (two-axis sensors) at its base. When tilting the [[http://​www.mybetinfo.com/​|online bet]] sensor, the electrical resistance between the center electrode and the electrodes at the periphery will vary proportionally to the tilt angle. 
- 
-Examples of commercial continuous inclination sensors exist with ranges between ± 1º to ± 80º (The Fredericks Company). 
- 
-Other implementations of continuous inclination sensors may use an LED and arrays of photodetectors (Fraden 2004, pp. 258).  
- 
-Finally, [[Accelerometer|accelerometers]],​ with sensitivities around a few //g// (1 g = 9.8m/​s<​sup>​2</​sup>​),​ can also be used to measure inclination. ​ One example is the ADXL 105 (one axis, ±5 g) or the ADXL 202 (two axes, ± 2 g) or the Memsic 2125GL 2-axes thermal accelerometer (also with a ±2 g acceleration measurement range). ​
