Product type, what can we do for you?





PCH Engineering A/S

PCH Engineering A/S is an ISO 9001 certified Danish production company focusing on equipment for monitoring of vibrations. Our focus on vibration monitoring and analysis have resulted in a unique set of competencies. We were the first to develop a digital vibration monitor for structural wind turbine surveillance and today we are first-movers within the field of real-time vibration safety monitoring and control.

With over 20 years of experience, we offer a wide range of monitoring solutions for traditional rotating machines, like decanters, blowers, fans, compressors, gearboxes and wind turbines.

Wind turbine protection

Our monitoring portfolio includes advanced vibration monitors, accelerometers, transmitters, proximity probes and sensors with the aim of providing customers with millisecond feedback and alarms based on current running conditions. We focus on fast-reacting vibration measurements, making it possible to prevent or limit the impact of unexpected breakdowns of rotating machinery.

As part of our quality assurance, we perform quality control where all products are 100% tested before shipping.​


About us

Life time of experience

We have a high degree of experience in product development and customer support. With an average seniority of 8 years the engineering and support team have been able to provide customers with high level of comfort through reliable and to the point support resulting in a high level of customer loyalty.

Our philosophy

Our company operates in the security field. Our products are intended for protecting of rotating machines and structures against unplanned crashes and prevent people from getting into danger and avoid total collapses. We operate primarily as an OEM manufacturer and sell permanent solutions installed in our customers' machines. One or more vibration monitors are typically incorporated directly in one machine. Our main customers are therefore manufacturers of rotating machines and wind turbines. Our products are therefore a part of our customers’ value chain with the aim of increasing their competitiveness, and security levels.

Reliable partner for protection

Whether you are the final user, an OEM or a distributor we strive to be the best partner for you in machine protection matters.

We work fast, are flexible and are financially strong and follow all the necessary international production standards, regulatory standards and quality standards.

Policies and Certificates

Our clients are active in the global market with high demand for standardization in products.
We carry a range of relevant certificates for our company and products, both CE, ISO, ATEX, GL and UL.

For SIL-rated vibration monitors we can present the SIL Declaration of Conformity according to EN 13849-1 documenting all safety calculation like The Safe Failure Fraction (SFF), Diagnostic Coverage (DC and Mean Time To Dangerous Failure (MTDFD).

As a responsible and international company PCH has defined various policies:

We supply customized monitors to a large number of machine manufacturers in the wind, cement, energy, food and chemical industry on a regular basis. Our typical customers are both end-users, who are supported through our worldwide distributor network, as well as OEMs, who design and deliver critical rotating machinery as part of turn-key solutions.

We are widely recognized for manufacturing products of high quality with high safety and functionality, which has been an instrumental reason to why our customers include some of the largest wind turbine OEMs.

For many years, PCH Engineering has developed and manufactured specialized equipment for large companies such as the Danish sound and vibration specialists Brüel & Kjær A/S.

Our history

For several years, Carsten Holm worked as an electrical engineer at Brüel & Kjær A/S. In 1989, he started his business of service and repair of electrical devices including B&K devices. Accompanied by other former employees of Brüel & Kjær, the company expanded within service, engineering, and manufacturing of analog vibration monitors, in 1992. The focus was to develop a DSP-based vibration monitoring concept to improve the monitoring of critical frequencies in pumps, blowers, decanters and even wind turbines.

The company started development of a full digital 2 channel vibration monitor, the PCH 1008, in 1996. Shortly after, in 1997, the company entered the wind turbine industry and developed special monitoring solutions within this industry.

After a few years, Leif Schaap and Ib Eriksen entered the company as CEO and CFO. Throughout the purchase of 50% of shares, they became partners and together built the modern and successful PCH Engineering as we know today. In 2000, the company launched the first DSP-based wind turbine monitor, the PCH 1026, which constantly has been updated with new hardware and features ever since. By 2002, the company received several certifications such as the ISO9001:2000 certificate and the first ATEX certification.

In 2015, a generation change was performed, and the company was taken over by Erhvervsinvest A/S with the intention to further develop the company.

In 2017, as part of a soft “generation change”, Leif Schaap decided to entrust the overall responsibility to someone else and instead stay as Executive Sales Director. In the search, for a new CEO who has experience with management and business development in niche markets, PCH Engineering and Erhvervsinvest chose to pass on the daily management to the former head of sales and marketing at Maersk Fluid Technology, Sune Lilbæk.
