Wireless diesel tachometer

JennovaTachometerJennova Inc., a specialist in smart energy management solutions, has developed a new patented Wireless Diesel Tachometer specifically designed to provide a simple, self-powered solution for generating tachometry readings from nearly any motor.

The process is based on the company’s patented Electrodynamic Energy Harvesting (EH) technology, which powers the device and enables the unit’s magnetic induction sensors to read RPM pulses directly from the engine’s motion and produce instant data, the company says.

“Gathering accurate and immediate diesel engine tachometry readings on a diesel engine has always been an extremely difficult process,” says Terry Pennisi, Jennova CEO and founder. “Prior to today, most solutions have involved cumbersome installations requiring complex calibrations.

“Jennova is focused on technologies that change the way we use energy. Our energy harvesting technology offers a revolutionary and virtually error-free method for capturing mechanical motion and reading the tachometry produced by almost any type of motor.”

The Jennova energy-harvesting method utilizes magnetic induction to power the tachometer’s RPM sensor and signal transmitter. Jennova says this is achieved through the capture and enhancement of energy created when a moving magnet passes by the conductor. In order to create the magnetic presence within a diesel engine or any other motor, the tachometer’s small neodymium magnets are attached to the flywheel or ideally a harmonic balancer. These magnets then create both the opportunity to harvest energy and the pulses needed to read RPM.

In addition to providing highly accurate readings, the entire installation process is performed in four simple steps in minutes. This starts by placing two to four magnets from the Wireless Diesel Tachometer to the motor’s flywheel or harmonic balancer with a simple cyanoacrylate better known as glue.

After attaching the unit’s transmitter with loop pad to the back of the engine compartment and sensor head to the engine fixture or hose using the spacing gage sent with the installation kit, the RPM gauge only needs to be mounted to the vehicle cabin. Once completed, the tach is simply set to “4 cylinder” when used with two magnets and “8 cylinder” with four magnets. From there, the unit is ready to go, Jennova says.
