Some questions are more frequent than others. Here is a short summary of questions often asked regarding our sensors from DIS. Take this opportunity also to learn more about the possibilities we have for customized solutions!

I see that inclination sensors, acceleration sensors and tilt switches have the same family name (QG) in the product code. Why is that?

Technically, all these sensors are made with acceleration chips that measure g-forces (gravitational forces), hence the 'G’ in the name. The gravitational force of the earth is a special form of g-force.

An inclination sensor measures the angle with respect to the horizon in which the imaginary line from the center of the earth serves as a reference. The tilt switch uses this line to switch when a certain angle is reached and the acceleration sensor measures g-forces such as the gravitational force in the direction in which the sensor is sensitive (1, 2, or 3 axes). 

Can I buy sensors with a different cable type, cable length and connector?

Yes, you can. On our website you will find the standard versions of the DIS sensors. These sensors are mostly suitable for doing tests. If you need a (small) series of sensors,  custom-made sensors can be supplied. Basically we can supply all cables, cable lengths, connectors, gains etc. Please contact us for more information about this.

Can I buy sensors with a different range?

Yes, that's no problem at all. On our website you will find the standard versions of the DIS sensors. These sensors are mostly suitable for doing tests. If you need a (small) series of sensors,  custom-made sensors can be supplied. Basically we can provide all desired ranges. Please contact us for more information about this.

Can I buy different sensors with analogue output signal?

Sure you can. On our website you will find the standard versions of the DIS sensors. These sensors are mostly suitable for doing tests. If you need a (small) series of sensors,  custom-made sensors can be supplied. Basically we can supply all required analogue output signals such as 0 - 20mA, 0 - 5V , 1 - 9V, 0 - 10V etc. Please contact us for further information.

Can I buy sensors with a custom case?

Yes, you can. On our website you will find the standard versions of the DIS sensors. These sensors are mostly suitable for doing tests. If you need a (small) series of sensors we can develop a custom-made housing, for example a die-cast housing or turning and milling. Please contact us for a dialogue if you have such a request.

Can I use a sensor mounted horizontally or vertically?

Sometimes you can, but usually this is not possible. The correct mounting method is listed on the datasheet in the box left of the product photo.

Default:
1 - axis sensor from QG30- series: horizontal or vertical
1 - axis sensor from QG65/76- series: vertical
2 - axis sensor: horizontal

Should this be a problem in your application, please contact us. Sometimes it is possible to adjust the sensor to make a different method possible.

The centering of a sensor fails. What could be wrong?

For safety reasons the centering feature is only available during the 1st minute after power-up and for another 1 minute after a successful centering action. Centering is done by connecting the sensor to the centering wire (not connected/ loose). Then you have to hold the centering wire for at least 0.5 seconds to 'ground'. The sensor has to see the transition from 'loose' to 'ground'.

In addition, some sensors (usually the ones that are mounted horizontally) has a centering – range which is limited to ± 5° pertaining to horizontal to prevent the sensor is centered at eg. 30° tilt and not functioning properly. Vertically mounted sensors have no range limitation and can be centered over the full 360°. A possible limitation of the centering function is always specified in the datasheet.
