AMETEK Introduces the RX0424, an All-New Rugged Accelerometer Instrument

Posted by Jon Semancik on Feb 12, 2019 9:39:37 AM

AMETEK VTI's new RX0424 IEPE/Voltage Instrument is a cost-effective new device that is ideal for measuring acceleration forces and sensing static and dynamic movement or vibrations. Fully-integrated IEPE current excitation and tachometer input channels further enhance the instrument’s utility and functionality.

The RX0424’s precise signal path design delivers laboratory-grade measurements to the field. The RX4024 provides exceptional accuracy and repeatability by using independent 24-bit analog-to-digital converters at programmable data acquisition rates up to 204.8 kSa per second. Multiple input ranges help ensure that users capture all vibration events, large or small, and precision

The RX4024 connects directly to Integrated Electronic Piezoelectric (IEPE) transducers, which have a built-in charge amplifier or voltage amplifier. IEPE current excitation sources can be programmed to supply either 4.5 mA or 10 mA drive current. These sources can also be tailored to specific application demands.

Total cost of ownership is more than just price

Posted by Grady Keeton on Jan 4, 2018 10:01:29 AM

When you purchase a power supply, you need to take into account more than just the price of the supply. The price is just one of the factors in the total cost of ownership. Other factors include:

Introduction to IEC 61000-4-11, Part II - AC source requirements

Posted by Grady Keeton on Aug 2, 2016 10:04:39 AM

In Part I, we introduced you to the concept of testing equipment for immunity to voltage dips and short power interruptions in accordance with IEC 61000-4-111. In addition to specifying the test waveforms, the standard also specifies AC source requirements for full compliance testing.

Introduction to IEC-61000-4, Part I

Posted by Grady Keeton on Jul 25, 2016 4:14:32 PM

Mains voltage dips and short interruptions can be caused by a wide variety of phenomena and can cause equipment to operate unreliability, and in some cases, can damage the equipment. Faulty loads on an adjacent branch circuit, for example, can cause a circuit breaker to trip, and high-power loads such as welders, motors and electric heaters can cause voltage variations. Natural events, such as power lines downed by storms or lightning strikes, may also disrupt mains power.

EN61000-3-2 Sets the Standard for Harmonic Currents

Posted by Grady Keeton on Aug 4, 2015 2:22:36 PM

While switch-mode power supplies have many advantages, one of their disadvantages is that they are a non-linear load, and because of that can inject harmonic currents into the electrical distribution system. Devices with switching supplies include domestic appliances (TVs, microwave ovens, lighting equipment and dimmers), and office equipment (PCs, printers). Motor-driven equipment can also cause harmonic distortion.
