The Pointek ULS200 is an ultrasonic non-contacting switch with
two switch points for level detection of bulk solids, liquids and
slurries in a wide variety of industries; ideal for sticky materials
The noncontacting Pointek ULS200 is virtually immune to the problems
inherent to most contacting level detection devices and is unaffected by
the presence of suspended solids in a liquid application.
The ULS200 system combines the sensor and the electronics in a
single, lightweight body. The ultrasonic sensor continuously emits sonic
pulses that are reflected as echoes from the target surface. By measuring
the time delay between transmitted and reflected pulses, the levels at
• 2 switch outputs for high-high, high, low and low-low level
alarms or pump up/pump down control

• Threaded and 3A approved sanitary fitting clamp process connections
• Polycarbonate enclosure, Type 6/NEMA 6/IP67
• Easy, two-button programming
• Noncontacting point level detection on bulk solids (0.8 to 9.8 ft.),
liquids and slurries (0.8 to 16.4 ft.)
• Two-button setup, simple cable-entry
wiring, and a self-cleaning sensor
• Power 100 – 230 V ac power supply
• This is the Sanitary version with an industry standard flange
To meet the need for configurations that are effective in standard
processes as well as class/zone approved applications, a chemically-resistant sensor. This extends the unit’susage to chemical, petrochemical and water, and wastewater industries,
where more rigorous approval levels are required.
When compared to other point level detection products, the Pointek
ULS200, with its unique and powerful features, delivers a cost-effective
The measuring range for bulk solids is max. 3 m (9.8 ft) and 5 m
(16.4 ft) for liquids and slurries. Unlike invasive contacting devices,
there is no material buildup on the sensor.
The level switch has a rugged design, combining the transducer
and electronics in one durable device. It has no moving parts
and is virtually maintenance-free.
The transducer, is inert to most chemicals. This means the device can be used in the
chemical, petrochemical, water and wastewater industries. This
sanitary version of the ULS200, with an industry standard flange
is easy to remove from the application for cleaning. It
thus satisfies the prerequisites for use in the food, beverage and
pharmaceutical industries. The Pointek ULS200 delivers superior
performance while reducing maintenance, downtime and
• Key Applications: liquids, slurries, fluid materials, plugged
chute detection, chemical industry
This low-cost ultrasonic point level switch permits non-contacting
detection of two distinct levels of liquids, slurries and bulk
solids. The measuring range for bulk solids is max. 3 m, and 5 m
for liquids and slurries without ever touching the product. Unlike
invasive contacting devices (bubblers, floats), there is no material
The level switch has a rugged design, combining the sensor and
electronics in one compact device. It has no moving parts, and
is virtually maintenance-free.
The transducer is inert to most chemicals. The Pointek ULS 200 delivers superior
performance while reducing maintenance, downtime and

or current runs, contactors and SCR control drives.
Locate the Pointek ULS200 so that it has a clear sound path perpendicular
to the material surface. The sound path should not intersect
the fill path, rough walls, seams, rungs etc.

Installation Couldn’t be Simpler
Just mount the compact Pointek ULS200 unit on the top of the vessel
with a standard 2†fitting, connect it to the appropriate AC power
supply, set detection levels using the two built-in programming keys.
That’s it! No need to shut down the process or fill/empty the vessel. The
sanitary model is easy to remove and clean — a key requirement for
food and beverage processes.The Pointek ULS 200 should be mounted in an area that is within
the temperature range specified and that is suitable to the hous-
ing rating and materials of construction. The cover should be
