Pointek ULS200
Pointek ULS200 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. Pointek ULS200 is used to measure liquids, slurries, and fluid materials, as well as
chemicals and plugged chute detection.
Pointek ULS200 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. Pointek ULS200 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 Pointek ULS200 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 CLS 200.
WARNING: Changes or modifications not expressly approved by Siemens
Milltronics could void the user’s authority to operate the equipment.
Notes:
• Pointek ULS200 is to be used only in the manner outlined in this manual, otherwise
protection provided by the equipment may be impaired.
• This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency based
communications.

Installation
Mounting Location
Recommendations:
• Ambient temperature within -40 to +60 °C (-40 to +140 °F), -20 °C (-4 °F) if metal mounting.
• Easy access for viewing the display and programming via two push buttons.
• An environment suitable to the housing rating and materials of construction.
• Keep the sound path perpendicular to the material surface.
Precautions:
• Avoid proximity to high voltage or current wiring, high voltage or current contacts, and to
variable frequency motor speed controllers.
• Avoid interference to the sound path from obstructions or from the fill path.
Mounting Instructions
Pointek ULS200 is available in three thread types: 2" NPT, 2" BSPT, or 2" G.
Before inserting Pointek ULS200 into its mounting connection, ensure that the threads are of
the same type to avoid damaging them. Simply screw Pointek ULS200 into the process
connection, and hand tighten.
WARNINGS:
• Materials of construction are chosen based on their chemical compatibility (or
inertness) for general purposes. For exposure to specific environments, check with
chemical compatibility charts before installing.
• Explosion hazard. Substitution of components may impair suitability for Class I,
Division 2 applications.
• This product can only function properly and safely if it is correctly transported,
stored, installed, set up, operated, and maintained.
• The user is responsible for the selection of bolting and gasket materials which will
fall within the limits of the flange and its intended use, and which are suitable for
the service conditions.
Note: Installation shall only be performed by qualified personnel and in accordance with
local governing regulations.
Note: Ideally, mount Pointek ULS200 so that the face of the transducer is at least
250 mm (9.84") above the highest anticipated level.
