WARNING
Improper device modifications
Risk to personnel, system and environment can result from modifications to the device,
particularly in hazardous areas.
• Only carry out modifications that are described in the instructions for the device. Failure
to observe this requirement cancels the manufacturer's warranty and the product
approvals.
Note
The device is to be used only in the manner outlined in this manual, otherwise protection
provided by the equipment may be impaired.
The device is an ultrasonic based process level switch providing high or low switch action on
liquids or solids. The sensor is ETFE or PVDF, allowing it to be used in a wide variety of
industries. The device is used to measure liquids, slurries, and fluid materials, as well as
chemicals and plugged chute detection.
The device contains an ultrasonic transducer and temperature sensing element. The
transducer emits a series of ultrasonic pulses. Each pulse is reflected as an echo from the
material and sensed by the transducer. The device processes the echo using Siemens'
proven Sonic Intelligence techniques. Filtering is applied to help discriminate between the
true echo from the material and the false echoes from acoustical and electrical noises and
agitator blades in motion. The time for the pulse to travel to the material and back is
temperature compensated and then converted into distance for display and relay actuation.
The device is an excellent primary detection device, but should not be used as a backup
device. For backup devices use a contacting technology such as the Pointek CLS200.
