The ToughSonic 12 is a rugged ultrasonic level AND distance sensor with a PVDF transducer. The ToughSonic 12 has built-in 0-10VDC, 4-20mA, and choice of RS-232 or RS-485 serial communications. The ToughSonic 12 also has built-in sourcing or sinking switches to control relays, alarms, motors, sirens, and more. All ToughSonic sensors are IP68 rated, and the ToughSonic 12 is built in a 316 stainless steel housing, with potted in and protected PUR cable and electronics. Available with 30mm or 1 inch NPT threads, and also available as Serial Only (no analog outputs or switches)
