The Thermo Electric Instrumentation laboratory is much more than yet another calibration facility. The entire staff is continuously striving to maximize its usefulness and support. For some customers this means a down time saver, because they can enter the instrument data and skip time consuming adjustment procedures. For others it’s a one-time shopping because it is possible to combine temperature, electrical and time based measurements.
For various reasons, such as:
– lead time;
– problem solving;
– customer specific methods;
– qualification procedures;
– clean room suitable calibration with corresponding packaging;
Thermo Electric offers an in-house portfolio that comprises:
– ISO-17025 (ILAC, COFRAC, etc.) calibration;
– Thermo Electric Instrumentation calibration;
– production line calibration;
– batch calibration;
– programming (which isn’t really calibration) including Callendar van Dusen;
– adjustment (not really calibration either).
It is imperative to clearly understand the customers’ definition and description of calibration. For example, batch calibrations sometimes are defined as merely the data of the MI-cable without any real measurements, sometimes customers desire specific parts of a batch to be calibrated as an instrument, and sometimes according to the ISO17025 procedures.
The desired accuracy and the related uncertainty often merit a week long training to reveal the magic of statistics.
Other information our experienced sales department needs to carefully distill out of specifications or inquire from customers, relate to things like insertion depth and the actual range the desired accuracy relates to. At first glance insertion depth may seem to be irrelevant, however, heating a type K thermocouple for annealing or calibration purposes causes a change. The part that sticks out of the equipment during calibration remains rather unchanged. Still, combined in one instrument, these two hold the promise of an inhomogeneity, causing errors when a temperature difference over that location occurs.
In order to achieve the impressive measurement capabilities as listed on https://www.rva.nl/scopes/details/K065 , and still be able to perform within an interesting price range and time frame, Thermo Electric offers :
- the people;
- the environment;
- the equipment.
The people: a senior calibration engineer with industry wide renowned knowledge, calibration engineers, experienced sales engineers and inspired management.
The environment: a “clean-room” laboratory, where temperature, humidity and stress levels are well managed.
– high end tube furnaces to reach 1500 °C within ISO17025;
– liquid salt bath to be able to offer a CMC of 0,092 °C at 600 °C;
– motion guide system to position multi level sensors as part of a fully automated cost saving system;
– liquid baths, triple point cells, other primary and work-standards;
– programming / communication equipment for HART®, bus systems and major transmitter
Apart from our own quality system and the ISO-17025 accreditation, our facility is very active in participation in inter laboratory comparisons worldwide. These comparisons show our customers, auditors and us that our measurements hold a high level of reliability.

The TEI type-approval for :
The approval is also valid for AUT-UMS, AUT-CCS, AUT-PORT and AUT-IMS meaning :
- UMS- Unattended Machinery Spaces
- CCS – Centralized Control Station
- PORT – Automated Operation in Port
- IMS – Integrated Machinery Spaces
Along with these temperature sensors which are manufactured in Waddinxveen, we also offer other sensors with Marine-approvals such as pressure sensors made by Gems and Besta level switches.
Recently Thermo Electric Instrumentation has expanded their vast range of certificates with the MID (European Measuring Instrument Directive) approval.
The goal is to set standards regarding measurement precision for the accurate billing of quantities of liquid or gas. At first glance flow, level, mass and volume seem to be the only parameters that play a role. If you realize however that all these liquids and gases that are being pumped around, stored and payed for, expand when they get hotter, and shrink when they get colder, you understand the extra liters or gallons you gain or lose from a few milligrades of temperature difference, count for quite a sum over the years.
Another application is the measurement of heat flow itself. In this case temperature difference between two or more sensors is used to calculate the amount of energy transferred. This applies for both heating and cooling equipment.
Thermo Electric Instrumentation has been manufacturing instruments for this purpose based on their ISO17025 approval. However, many of our customers manufacture flowmeters or metering equipment and need to comply with this MID.
As part of the approval procedure, our RTD-sensors were calibrated and witnessed in our own in-house laboratory at different temperatures, ranging from -196 °C to 550 °C, using liquid nitrogen, melting ice and liquid salt baths. Another part of the procedure was about the electrical immunity of our designs.
The main groups of our customers Thermo Electric Instrumentation intends to serve with this feature, are the main transmitter manufacturers or dcs-system suppliers and the manufacturers of flow metering equipment.
Below : a picture of some of the actual sensors used in the approval process.
Thermo Electric Instrumentation will attend ADIPEC 2016 (07-10 November) in Abu Dhabi, United Arab Emirates; the world’s most influential international exhibition and
conference for the Oil & Gas market. You can visit us at the IRO Dutch Pavilion, Hall 11, booth number 11234.
Thermo Electric Instrumentation strengthens its focus on furnace and boiler industry, revolutionary design meets customer design and performance criteria
In the field of tube skin or boiler temperature sensors Thermo Electric Instrumentation has much to offer. The way Thermo Electric Instrumentation knows how to combine knowledge, portfolio, research, welding and project management is a key factor to the success.
First and foremost Thermo Electric Instrumentation is able and willing to take a closer look into the exact needs and expectations of the end user. The extensive feedback and investigations have resulted in a number of special features with a proven track record.
Being able to avoid bending during elongation of the boiler tubes has provided us with the possibility to come up with an extremely resistant construction, with ceramic plasma coatings. This very same development gave us the opportunity to develop a truly online retractable skin thermocouple. Both have been tested and investigated thoroughly. After years of service, the online retractable skin thermocouple proved easy and useful. The resistance to the harsh combustion environments has been investigated through a number of destructive and non-destructive tests, and the mere fact that they have outlived their predecessors by far proves this.
When to use a shield, the location of the thermocouple within the shield and the dimensioning, positioning and welding are, as expected, of key importance to the reduced influence of the irradiation by the burners and heat flow from the gasses.
Nevertheless, the more classic and standard designs with expansion coils and regular weld pads or offline retractable designs show an ever increasing demand, especially when combined with the more resistant alloys and our project support during the exciting period of a shut down or revamp.
The revolutionary new “non-welding” design has been in service for over a year now. Measurement output is much closer to reality, due to an improved contact between tube and thermocouple sheath. Expect us to keep you informed over the years to come.
