SENSORS, TEST & CALIBRATION Series 7014Unifloat™ Level Sensors DESCRIPTION The BIW Unifloat level sensing system was developed especially to permit simple, low-cost installation and ease of adjustment in service for a broad range of applications requiring accurate multiple function/multiple level control of any type of liquid. FOUR BASIC COMPONENTS As illustrated at left, this advanced new system consists of just four basic components: (1) A single MAGNETIC FLOAT that is free to travel up and down with the rise and fall of liquid. Standard material is 316 S.S. (2) A GUIDE TUBE of any...

Because of its inherent simplicity, the BIW Unifloat™ Level Sensor concept provides many features and advantages not offered by other float type level sensing devices. Among them: Fewer Parts/Lower Costs—Use of one free-moving float to actuate up to 12 hermetically sealed and encapsulated reed switches eliminates expense and problems involved in mounting a separate float plus float stops at each operating level. Ease of Installation— Suspending all reed switches on a common circuit return line simplifies assembly and installation. Just slide switches up or down to desired control levels and...

SENSORS, TEST & CALIBRATION OTHER APPLICATIONS WITH TYPE C REED SWITCH Having Common Grounded Contact The line diagram below shows the wiring method recommended when operating conventional relays and devices rather than BIW relays. To meet UL requirements, the control power must be from an isolation transformer with the common side grounded. This means that the Unifloat switches are connected in the grounded side of the relay coils rather than the hot side. If this causes a circuit design problem, then the Type I isolated contact reed switches should be used in the Unifloat. AC Line Voltage...
