Alarm contacts with electronic contact

Service intended Electronic alarm sensor contacts are switches for tensions out a range of 10 - 30 V DC used for direct drive of a stored program system or other electronics. The signal output is instantaneous and analog to the movement of the instrument pointer. Liquid filling in the instrument is possible.
