SensorLab can assist in the whole range from design and engineering to production and assembly of anything from parts to turn-key applications thanks to their in-house designer, advanced test and qualification facilities (measuring equipment, autoclaves, furnaces, assembly test loop, etc.).

The SensorLab runs highly advanced workshop facilities, such as Computer Numerical Control (CNC) lathes, 5-axis milling machines, Wire Electrical Discharge Machine, Cavity Electrical Discharge Machine, laser welding equipment etc. To operate all of this SensorLab have an excellent staff and multi-disciplinary, highly skilled and experienced people.

SensorLab is the continuation of a strong legacy from the time it was known as the Instrument Workshop in connection with the Halden Boiling Water Reactor (HBWR); this reactor was permanently shut down until June 2018. All of this gives SensorLab a great advantage working with design, development and production of custom applications.

SensorLab manufactures nuclear grade instruments and have a portfolio of very robust Linear Variable Differential Transformers (LVDTs) capable of coping under the most demanding conditions. The current LVDT line-up is designed for applications from cryogenic (-200°C) to high temperature (700°C) and have a pressure rating of 250 bar (at 20°C).

The Halden Boiling Water Reactor (HBWR) started operation in 1958, being originally built to demonstrate the usefulness of nuclear power as an energy source for the process heat  industry. During its first years of operation for the internationally funded Halden Reactor Project (HRP), the reactor was predominantly used for investigation of fuel properties and flow instabilities (the HBWR is operated relying upon natural circulation).

In order to carry out broader research programmes on fuel in the Halden Boiling Water Reactor, reliable in-core instrumentation was needed for measuring key parameters for fuel and material performance such as fuel temperature, rod internal pressure, fuel pellet volume changes and cladding dimensional changes. Thus, different instruments were designed and manufactured in-house. One of the most important instruments developed is the Linear Variable Differential Transformer (LVDT).

We have manufactured nuclear grade instruments snice the beginning of the 1960s. The LVDTs have been continuously improved over the years and we now have a portfolio of very robust LVDTs capable of coping with the most demanding conditions.

The current LVDT line-up are designed for use from cryogenic applications (-200°C) to 700°C and with a pressure rating of 250 bar (at 20°C).


SensorLab capabilities

The SensorLab have in-house advanced workshop facilities, design capabilities (Autodesk Inventor) , instrument manufacturing, electronics lab,  and numerous testing facilities.

The machine park consists of computerized lathes, 5-axis milling machine, Wire Electrical Discharge Machine, Cavity Electrical Discharge Machine,  laser & TIG welding equipment etc.

Highly skilled and experienced staff operating the machines

The 5-axis milling machine, often in conjunction with the wire EDM, can make complex parts impossible to make in less sophisticated machines.

To be able to use the machines at its full potential, highly skilled and experiences staff is needed to be able to program the CNC machines.

3D models received from our designers are used as input when programming the 5-axis milling machine.

The picture to the right show an example of a part being made using  the 5-axis milling machine in combination with the wire EDM.

Originally, this was made up of 12 small  pieces welded together; thanks to the afore mentioned machines, it is possible to make the part in one piece.


Another example of parts being made in the machines.

The 17 mm long cannon is made in the 5-axis machine.

The wire EDM can make complex pieces with different shapes on top and bottom as the upper and lower wire guides can be moved independently of each other.



Cable-nipple laser weld

The laser welder makes it possible to weld very small and thin walled pieces together. This picture show a mineral insulated  cable with Inconel 600 sheath. The outer diameter of the cable is 1.0 mm and the wall thickness is 0.1 mm. This cable is welded to a nipple (the weld is to the right side of the nipple). The nipple can then be welded to a larger body without destroying the thin and fragile sheath of the cable. Wires and thin plates/membranes <0.1 mm thick can also be welded together in the laser welder.
