AMETEK BW CONTROLS . 1500-D-L3-S8-OC-X

B/W 1500 series relays provide versatile and reliable liquid level control without the use of floats. The 1500-D relay can be used as a pump up control on supply pumps to fill elevated tanks. It can also be used as a high level or low level signal control. The 1500-D relay has one normally open contact and one normally closed contact. B/W 1500 series control relays can only be used to sense conductive liquids. They are not suitable for oil, gasoline, animal fats, and other similar materials. B/W 1500 relays should not be used with flammable liquids. Liquid levels are established by mounting or suspending electrodes in the tank or vessel. Electrodes are sold separately.
