Report on Test of "Agastat" Time Delay Relay
Abstract
Recommendations-In view of the facts determined from this test it is recommended that the Bureau approve of the "Agastat" relay for use in Naval radio transmitting equipment providing the following modifications are made: (a) That the coil supports be secured by means of brass screws and lock nuts or lock washers so that the coil may readily be removed for replacement, (b) That the parts used in the fabrication of the relay be made of non-corrosive materials or that the materials used be so treated as to prevent corrosion or rust. Results-The tests conducted with the two "Agastat" relays submitted indicate that extreme care must be exercised in the manufacture of the units to prevent too great an amount of gas from being introduced into the control chamber. In order that no danger be incurred from the use of this type of relay in the Naval Service, it is believed that all relays should be capable of successful operation at temperatures up to 70 degrees Celsius.
