DuoTech accelerometers
In the DuoTech® accelerometer, two of the most widely used and successful methods for monitoring mechanical condition come together: vibration and shock pulse measurement. The combination of the patented HD ENV and SPM HD measuring techniques provides maximum flexibility, enabling superior lubrication and bearing monitoring as well as detection of vibration-related problems.
Superior combination of HD measurement technologies
The ability to use a single sensor for vibration or shock pulse measurement – or both – provides maximum flexibility to select the optimal measurement technology for a given problem or application. DuoTech is an individually tuned piezo-electric accelerometer delivering excellent performance in a very large area of applications.
Performance without compromise
Digital technique and carefully engineered mechanics provide very impressive performance characteristics. The DuoTech accelerometer provides consistent, high-precision readings in the low and high frequency range. The robust design makes DuoTech an appropriate choice for a wide variety of industrial applications, including harsh and potentially explosive environments. For measurement with portable data collectors and analyzers, the DuoTech quick connector version enables flawless signal transmission.
TWO-IN-ONE FLEXIBILITY
EFFICIENCY BOOST
PERFECT FOR RETROFITS
“DuoTech joins the best of two cutting-edge monitoring technologies. The scope of machine problems that can be detected and monitored, the clarity of the measuring results and the forewarning times made possible with HD ENV and SPM HD – they are all unparalleled to other measuring techniques.”
- Stefan Lindberg, CEO of SPM International

QUOTES FROM OUR CUSTOMERS
“After twelve years of condition monitoring with portable instruments, we see a great benefit in having an online condition monitoring system that can help us see in real time the dynamic behavior of the machine and also to determine how the changes in technological parameters are influencing that. All of that will help us to further increase the speed of the machine, and with that the productivity. DuoTech was the decisive argument for choosing SPM, being able to provide the benefits of both the vibration and shock pulse technologies. The ability to obtain a longer pre-warning time has also played an important role.“
-Radu Alexe, Predictive Maintenance Specialist at Vrancart S.A.

Installation materials
Connectors, cables, and service box
We offer a wide range of connectors in composite or stainless-steel material. Composite material provides benefits such as vibration dampening and weight reduction, while stainless steel can withstand mechanical forces and works both in high and low temperatures, etc.
For our connectors we have different types of cables, and to further secure the installation, we supply uncovered, acid proof stainless steel conduits. These are protective covers slipped onto the cable and fixed to the transducer at the connector. Stainless steel cable clips are available for holding the conduit. For protection of cable joints from moist and water, a stainless, acid proof steel service box is available.
