Tilt Switch FAQs

 

This information is applicable to the following products:

  • Hummingbird 2 Axis Tilt Switch (HMTS2CFG10B)
  • Hummingbird USB Configurable Tilt-Switch (HMTS2CFG0)

 

How do I reduce the effects of vibration on my Tilt Switch?

Imagine for a moment that your tilt switch is a glass tube with a ball-bearing in it. As you roll the tube left and right, the ball-bearing rolls left and right. Shake the tube and the ball-bearing rattles all over the place. Now add some water to the tube. The rate at which the ball rolls slow down and it's response to vibration improves. Now add syrup; the balls rolls really slowly but is much less prone to vibration. This is known as damping the tilt switch.

With electronics tilt switches, we have maximum control and can change the damping factor to reach an optimal response where the sensor is quick enough to respond but slow enough not to respond to the effects of vibration. Hummingbird Electronics' USB tilt switch is a good example of a tilt switch with configurable damping levels.

How do I install drivers for the USB configurable Tilt Switch?

Please download the tilt-switch configuration software from the manufacturer or distributor website. The download will be in the form of a zip file, which needs to be extracted before installation. Once extracted, double click on setup.exe and the software will install. Please note that the software will not be fully functional until a tilt-switch is connected to the computer via a USB port.

When the tilt-switch is first connected to a computer via USB, the Windows operating system will require a driver to be installed. The driver is included in the installation and can be found in a directory called \Drivers. Specify this directory when asked by the Windows operating system. Once installed, run the tilt-switch configuration software and press the connect button to connect with the sensor. The pitch and roll graphs should now start to operate indicating that a connection has been achieved.

 

Inclinometer FAQs

 

This information is applicable to the following products:

  • Dual Axis Inclinometer - Active, Incl. 1° Sensor (HMDS2000)
  • Dual Axis Inclinometer - Elite, Incl. 1° Sensor (HMDS8000)
  • Dual Axis Inclinometer, Elite 0.1° Sensor (HMDS8100)
  • Integrated Compact Inclinometer (HMDS0400)
  • Dual-Axis Inclinometer - Compact (HMDS0500)

 

Why is my inclinometer alarming at level?

Hummingbird Electronics' inclinometers can differentiate between left and right roll and forward and back pitch. Please make sure that limits to the front and right are setup as positive angles and that limits to the left and back are set up as negative angles. For an example, if your pitch settings are 40 degrees up and 60 degrees down, set the limits to +40 and -60.
