300Pa Switch Pres Air
Cause
In some applications the hysteresis of the sensor is important
Resolution
There are 2 types which can switch the 300 Pa: - SPD910-300Pa and SPD910-500Pa.
The hysteresis or switching differs from type to type because of range and the clip feather.
In general they are as follows:
SPD910-300Pa 0,1mbar +/-15%
SPD910-500Pa 0,2mbar +/-15%
SPD910-1000Pa 0,4mbar +/-15%
SPD910-2000Pa 1,0mbar +/-15%
