Multi Level Temperature Sensors
Thermo Electric Instrumentation manufactures and supplies multi-level temperature sensors across a variety of industrial sectors. Multi-level or multipoint temperature sensors as sometimes referred to, are industrial devices that measure temperatures at different points along the length.
We manufacture a range of these sensors ranging from single probe tubular devices – housing a number of profiling points, right up to heavy duty Thermowell designs with guide tubes – allowing sensor removal without shutting down the reactor or vessel.
Our Multi-level sensors are frequently used in chemical, petrochemical and refining industries, providing an excellent temperature measurement solution for chemical reactors, catalytic crackers and fractionation towers.
APPROVAL BY LLOYDS QUALITY REGISTER
Our experienced staff are always on hand to assist you with your sensing requirements. We only select the highest grades of materials based on your applications. Our production procedures and quality control system are fully approved by Lloyds quality register and our reputation for consistent excellence in multi-level temperature sensor manufacturing speaks for itself. ￼
We can supply a variety of profiling options with or without explosion proof certificates. All of our multi-level temperature sensors can also be supplied with mechanical or electrical test certificates, conforming to International standards.
PILOT PLANT MULTI LEVEL SENSOR
This construction consists of a small diameter protection tube for measuring the temperature in a pilot plant. The thermocouples mount straight into the inner-tube. Small diameters from 1.5 mm with up to 10 thermocouples are available. Overall length and design is flexible, depending on requirements.
SPRING LOADED STRIP CONSTRUCTION
We offer this type of multi-level profile with either thermocouples and/or Pt100 elements. Mounted in a protection tube, each element is spring loaded to the inside wall of the tube to increase both response time and accuracy.
SPRING LOADED STRIP CONSTRUCTION B
For thermocouples and RTD’s. Complete with a spring-loaded construction for measuring the temperature at the inner-wall of the thermowell.
REPLACEABLE INSERTS CONSTRUCTION
For thermocouples and RTD’s. Consisting of replaceable inserts. Complete with support tubes which have an open end for connecting to the inner-wall.
REPLACEABLE INSERTS CONSTRUCTION B
For thermocouples and RTD’s. Consisting of replaceable inserts. Complete with support tubes which can be welded to the inner-wall.
Due to increased regulation requirements within the refining and petroleum industries, Thermo Electric Instrumentation have developed a Proflexi® “Radial” multipoint thermocouple assembly. This design provides a more accurate representation of vessel contents due to the unique radial design.
ACCURATE MEASUREMENT AND REPRESENTATION
Standard multi-level constructions can limit or mislead operators. This is due to the design or location at the point where the measurement is being taken. In order to address the need for a more accurate representation of a vessel contents, we have developed the Proflexi® assembly. This unique type of multipoint assembly is available in a range of material and construction options to match your process requirements.
Thermo Electric Instrumentation can help you with the design for your next multi-level temperature sensing project. We utilise our industry knowledge and extensive experience in order to match available products to your process conditions. This consultative approach to product design and manufacturing ensures that our customers receive the best possible service and the right product for their process.
We have dedicated manufacturing and testing facilities located in the Netherlands. Our Thermo Electric temperature sensing products are supplied directly from our headquarters to our customers, through sales and service centres across the globe.
HIGH STANDARDS AND EFFICIENT SUPPLY
Our dedicated central production and engineering facilities allow us to maintain our high standards and best practice in engineering and design. This expertise is reflected in the efficient supply of Thermo Electric temperature sensors and in our consistent achievement of quality in the field.
