The WL750 Ultrasonic Level Transmitter is perfect for short range, non-contact tank level measurements for a variety of liquids and solids
With its narrow 8 degree beam angle and slim 1.38 in (35mm) chemical-resistant process end, the WL750 is designed for accurate level measurements even in relatively small tanks. Purchase of the WL750 includes a 3-bolt 2-3/4 inch flange for use in secure mounting.
Capable Data Display and Transmitter
The WL750 includes an integrated LCD display, user interface, and transmitter unit that provides a local level readout and the ability to send a scalable, 4-20 mA signal to another device. The display/ transmitter also features user-programmable settings and an LED alarm light. TheWL750’s optional power and signal cable assemblies connect to the display unit with a molded on, locking 5-pin plug.
Flexible Signal Cable and Power Options
You can select an optional signal cable assembly that will connect to the WL750 display’s 5-pin plug. Choose from 6-foot (2m) (Option WL750-CBL-2) or 16-foot (5m) (Option WL750-CBL-5) cable assemblies. If you would like to create your own longer cable runs, you can simply purchase the unit with just the 5-pin plug. The WL750 will work with up to 3,000 feet of the appropriate signal cable. Please note, either a cable assembly or 5- pin plug is required. Flexible power options are also available for the WL750, such as the IDEC 24 volt power supply (see Ordering & Options).
