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, available in ETFE or PVDF copolymer, is inert to most chemicals.
This means the device can be used in the chemical, petrochemical, water, and wastewater industries.
A sanitary version of the ULS200, with an industry standard flange option, 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 equipment replacement costs.
Key Applications: liquids, slurries, fluid materials, plugged chute detection, chemical industry
The Pointek ULS200 should be mounted in an area that is within the temperature range specified and that is
suitable to the enclosure rating and materials of construction.
The cover should be accessible to allow programming, wiring and display viewing.
It is advisable to keep the Pointek ULS200 away from high voltage 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.
Mounting and Interconnection
The Pointek ULS200 is available in three thread types: 2" NPT, R 2" (BSPT), EN 10226 or PF2 and can
be fitted with the optional 75 mm (3 inch) flange adapter for mating to 3" ASME, DN 65, PN 10, and JIS 10K 3B sized flanges.
Separate cables and conduit may be required to conform to standard instrumentation wiring or electrical codes.
