Kvaser D-sub 9 pin 120 Ohm Termination Adapter

 

Kvaser D-sub 9 pin 120 Ohm termination adapter is a CAN adaptor with a 9-pin male D-Sub connector at one end and a 9-pin female D-Sub socket at the other. Between CAN High (pin 7) and CAN Low (pin 2) there is a built-in 120 Ohm CAN terminating resistor.

This adapter provides quick and easy termination to any Kvaser high-speed CAN product. The Kvaser CAN termination adapter is used when there is a need to terminate a CAN node without internal termination or when no CAN node is connected to the bus. The Kvaser D-sub 9 pin 120 Ohm termination adapter has a 9-pin male D-Sub plug connector and a 9-pin female D-Sub socket. A 120 ohm terminating resistor sits between pins 2 and 7.

Transmille introduces AC/DC precision shunts

 

The Transmille AC/DC precision current shunt range consists of a selection of low-inductance coaxial current shunts, this wide range of shunt values enables measuring from 1 mA to 100 Amps. The current shunts are specially designed for laboratory use when making AC or DC current measurements as well as AC/DC current transfer measurements. These shunts help simplify precision AC/DC current measurements.

The physical design and the high quality components used in the current shunts ensure a flat response across a wide range of frequencies. These shunts have also been designed around the principle of low-inductance, low-capacitance and even heat dissipation to ensure high accuracy and stable repeatable measurements.

 

 Product Highlights

 

·         AC/DC differences as low as 1ppm

·         Superior accuracy compared to Wilkinson standard AC/DC resistors, minimising the use of correction factors for frequency response

·         Suitable for current measurement from 1mA through to 100A

·         Frequency range from DC to 30kHz

·         Low inductance & capacitance for flat frequency response

·         Simplifies calibration of precision calibrators and current sources

 

Each shunt is calibrated by UK’s National Physics Laboratory (NPL) to ensure the highest accuracy available. The coaxial design offers superior accuracy and low electromagnetic influence, ensuring a linear and predictable frequency response. Each shunt has a type N output connector to ensure low noise when measuring at high frequencies providing easy connections from the shunt to the measuring device.

Each of these shunts can be ordered separately or as a full set of 14 current shunts. The full set is provided in a bespoke transit case to ensure protection during shipment and storage. A low capacitance buffer amplifier for the 1mA shunt is also included.

Highlighted: The QPX1200L Power Supply of Thurlby Thandar Instrument

The QPX1200L offers users a level of flexibility that cannot be achieved with conventional laboratory power supplies. With a current capability of 20 amps at the maximum output of 60 volts, its PowerFlex design offers increasing output current with reducing output voltage. The QPX1200L can therefore perform the task of many different power supplies. Example voltage/current combinations include 60V/20A, 48V/25A, 37.5V/30A, 26V/40A, and 20V/50A.

With setting controlled by an instrumentation quality 16 bit DAC, the QPX1200L offers high accuracy and stability.

Mixed mode regulation with a linear output stage gives the QPX1200L exceptionally low output noise for a unit of this power, and ensures good transient response. Unlike most higher power laboratory PSUs, the QPX1200L is equally suited to bench or rack-mount applications. Output and sense terminals are provided on both the front and rear panels. The case has integral tilt feet, and a 3U rack mount is available as an option.

The QPX1200 has analog, RS-232, USB and LAN interfaces as standard, the latter conforming with the LXI standard. An optional GPIB interface can be specified at time of order.

 

Features:

·         PowerFlex design gives variable voltage/current combinations

·         Up to 60 volts and up to 50 amps within a power envelope

·         Linear final regulation provides very low output noise

·         Setting by direct numeric entry or by spin wheel

·         High setting resolution of 1mV in up to 60 volts

·         Multiple non-volatile setting memories

·         Bench or rack mounting with front and rear terminals

·         Analog, RS232, USB & LAN (LXI) interfaces standard, GPIB optional

Data Physics: Why Do I Need a Drive Adapter for a Slip Table System?

A drive adapter is basically what its name states: an adapter that connects the shaker to the slip plate. The drive adapter provides a transition from the shaker’s armature pattern to the slip plate. The typical drive adapter provided by Data Physics is either a welded construct or cast part. Both configurations are manufactured from magnesium so that they are as light as possible; rigid as possible; and damped as much as possible. All three of these characteristics, weight, rigidity, and damping are critical when conducting vibration testing.

 

Data Physics drive adapters attach to the shaker’s entire armature pattern so that the maximum amount of the shaker’s force is transmitted to the slip plate. By design, the force of the LE shaker is transmitted from the coil of the armature and that is located on the outer bolt circle. This is why it is so important that the outer bolt circle is included in the attachment of a drive adapter, as well as head expanders, fixtures, etc.

The objective of the drive adapter is to transmit the force of the shaker to the slip plate. The slip plate holds the test article in position so that it may be vibrated. If the connection from the shaker to the slip plate is inadequate, this will cause transmissibility issues. Transmissibility issues are a nightmare because the shaker has to work harder than normal to vibrate the test article. Transmissibility issues can also be very difficult to control. Therefore, to reduce the chances of having a transmissibility issue, due to an inadequate connection between the slip plate and the shaker, drive adapters are utilized.

Courses ‘Introduction to Vibration’ and ‘Fixtures, Software and Specification’

 

On October 6 and 7, 2015 we will organize again the famous two-days course ‘Introduction to Vibration’ and it will take place in Breda (NL). This course aims to give more insight knowledge to the attendees in:
- testing with a shaker system
- dealing with several kind of tests
- reading the theoretical test and the implementation of the test
- designing a fixture

Here you can find the contents of this course.

A second course ‘Fixtures, Software and Specifications’ will be organised on October 8 for those who are interested in aspects of vibration technology which lays beyond the introduction course. This day is intended to be an interactive course, where you can discuss problems related to vibration technology with the host(s) and your co-participants. You can even bring your own fixture(s), if you have questions about it and want to discuss it.




If you or one or more of your colleagues are interested in one or both courses, please inform us by clicking on the Mail button below.
