Who are we?

Ferry Toth

Dr. Ir. Ferry Toth became interested in capacitive sensors during an apprenticeship at Enraf-Nonius (now Enraf BV) in 1990. He was then involved in a  cost re-engineering of the STIC, which a a capacitive level gauge for underground storage tanks at petrol stations. Of this highly successful product Enraf has sold over 26000 worldwide.

 

After several projects at the Delft University of Technology involving capacitive personnel detection and a capacitive force sensor, he was employed by the university as PhD student on the STW project "DEL22.2777, Capacitive transducers for industrial use". Promoters were   prof. dr. ir. A.H.M. van Roermund, and dr. ir. G.C.M Meijer. Participant in the project were Enraf BV, RET Rotterdam, Smartec BV. and Philips Drachten. You can find a bibliography here. He became a specialist in the field of capacitive sensors and sensor interfaces with frequency output, like the Smartec SMT160-30 and UTI (see also IFSA).

 

Just before receiving his PhD degree in 1997 he joined Enraf again as a systems engineer to develop the successor of the STIC. During his time at Enraf he completed several projects (including 829 DataDIP, 762 VITO and 696 Marine Radar) and acquired much experience in the area of intrinsically safe electronic design (Ex i according to ATEX en FM).

 

With the start of  Exalon Delft and old wish has come true for him to share the risk and responsibility and at the same time to reap the benefits of his views and efforts

 

Erik Schnitger

Ir. Erik J. Schnitger graduated in 1986 at the Delft University of Technology at the Electronic Instrumentation Laboratory. After his studies he joined  Enraf-Nonius (now Enraf B.V.) in Delft, at the R&D department as electronics designer. 
During the over 17 years at his stay at Enraf, he has contributed greatly to the conception of the many successful instruments in Enraf's portfolio.

Examples include, the industry standard 854 Servo Level Gauge and the  862 MIR/MIT Temperature Transmitter with the unique Enraf 864 MTT Multi Temperature Sensor, the 873 Smart Radar and the 973 Smart Radar LT” and several other instruments.

Over the years he has gained a great expertise in the field of innovation, specification and design of industrial, explosion safe Weights and Measures approved instrumentation.  
His specializations include: extensive knowledge in the field of explosion safety, Ex (ATEX and FM), EMC, low voltage directive, analog electronics and sensor interfacing, low-power electronics, switched power supplies and design for production minimizing after care.


With the foundation of Exalon Delft he has taken a new challenge in the field of product development and innovation, and the opportunity to apply his knowledge and experience in wider application areas the the petrochemical industry. 

 

Xiujun Li

Xiujun Li was born in Tianjin, China on February 19, 1963. He received his B.Sc. in physics and M.Sc. in electrical engineering from Nankai University, Tianjin, China in 1983 and 1986, respectively. In 1997, he received his Ph.D. degree from Department of Electrical Engineering, Delft University of Technology, The Netherlands.


Since September 1996, he has been employed as assistance researcher at the Faculty of Electrical Engineering, Mathematics and Computer Science, Delft University of Technology, where he was involved in research and the development of smart capacitive sensors and low-cost interfaces for smart sensors.


Since 1997 he worked in part time for SMARTEC B.V. on smart temperature sensors and smart sensor interfaces. In 2002 he joined Bradford engineering B.V., Heerle, The Netherlands, where is performs research and development of instruments for the Space Industry.


In 2009 he joined Exalon Delft.

 

 

 

 

 

 

Willem-Jan de Hoog

Mr. de Hoog has been active in information technology and automation since 1989 when he joined the Delft University of Technology as Application Programmer. He continued his carrier at the The Social and Cultural Planning Office and  V2_Organisation. Following he worked as Software Engineer and International Project Manager at Lunatech Research and Morphon Technologies.

 

During this time most he was mostly involved with projects using databases, complex modeling, simulations and XML technology. At Exalon he has quickly taken the lead in setting up a low cost development platform for HART transmitters

 

Besides having a thorough knowledge of software engineering and ample experience in leading software projects that are executed by teams distributed across several countries he also has a good hand in configuring and administrating (internet) servers based on Windows, Unix and Linux.
