Visual barometric indicator and pressure sensor with opening and closing alarm relay switches for use in conjunction with safety shut down circuits for wind power installations.
Barometric pressure is one of the parameters used to determine air density which is a contributing factor in monitoring the amount of wind power to ensure a wind turbine generator does not exceed operational limits.
This barometric monitor combine a SRP-N1186 6 digital resolution digital monitor with alarm relay switches, which can be mounted on a wall, and a DMP 331i high accuracy barometric pressure scaled sensor which has been scaled to 800 to 1200 millibar absolute to optimise signal output resolution.
