AMETEK BW CONTROLS . 1500-A-L3-S4-OC-X

B/W 1500 series relays provide versatile and reliable liquid level control without the use of floats. The 1500-A relay has one normally open contact, and is commonly used for high level signal control. It can also be used as a low level cutoff when wired in series with a stop button in a 3-wire pushbutton station. 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. Users should consult Ametek B/W Controls documentation for detailed application information prior to purchasing or installing this item.
