The Ultrasonic Point Level Control produces an 8mA or l6mA current to indicate liquid

presence/absence within a sensor cavity. Two piezoelectric crystals face each other across

the sensor cavity. One crystal transmits an ultrasonic signal; the other crystal receives

the signal.

When the sensor cavity is empty, the receiver detects a weak signal because air is a poor

conductor of ultrasonic waves.

When process liquid fills the sensor cavity, the receiver detects a strong signal because

liquids are good conductors of ultrasonic waves.

The wet probe switch inside the electronics housing switches between 8mA and 16mA

output in the wet probe condition. Internal LEDs indicate the current output over the loop.

A red LED indicates 16mA current output, and a yellow LED indicates 8mA current output.

An optional timer is available to delay the current change from 0 seconds to 10 minutes.

The delay timer provides added process control, valuable for use in turbulent

conditions.
