Miniature amplifier modules for high resolution temperature measurement and calorimetry. Resolve micro degrees with Thermocouples.

EM Electronics – Nanovolt Amplifiers

EM Electronics was formed in 1979. One of the earliest projects undertaken was the study of very low level DC amplification.

The original prototype instrument was demonstrated to the Division of Electrical Science at the National Physical Laboratory in Teddington, and shortly after this a first instrument was ordered.

  • Selecting the Correct Nanovolt Amplifier
  • Ultra Low Level DC Voltage Amplifiers
  • Low Level DC Voltage Amplifier Modules

A22 is a low noise amplifier module for sensitive DC measurements, data collection and systems, and is ideal for very sensitive temperature measurement using thermocouples.

The A22 has many other features desirable in a measurement amplifier. The very high loop voltage gain of 100T, or 280dB, means that high overall gain may be used, controlled precisely by feedback resistors, thus ensuring good linearity, with the accuracy defined by the feedback resistors used.

Adjustable Output Positive Voltage Power-Supply Kit

Interface board conductivity

An electronics board (kit) that allows you to connect up to 30V AC or DC on one side of the board and get adjustable VDC regulated on the other side. Every lab should have a few of these boards handy. The boards will allow you to easily power all your analog components (i.e. op-amp). The Terminal Block TB connector is included and makes it easy to use.

Interface board conductivity cell with DIN Rail clip

Interface board conductivity

Build your own Conductivity meter and/or controller and save. Simply connect your Conductivity cell (conductivity electrode, Probe) to the input via Terminal Board (TB) and the output to analog to digital converter (ADC), Digital voltmeter (DVM), Analog Voltmeter, micro-controller (MC) or PLC. Power the board and get reading.

Bitscope – PC Oscilloscopes And Analyzers

BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes. This means they capture and display one, two or four analog signals and eight logic or timing signals, simultaneously. Any BitScope can be used as a Digital Storage Oscilloscope, Logic State Analyzer, Spectrum Analyzer or Data Recorder. USB BitScope 310

USB BitScope 310 – PC Oscilloscope

BS310U is a robust general purpose USB Mixed Signal Scope and Data Acquisition device. BS310U is backward compatible with BS300U which it replaces.

It has 4 times as much capture buffer, a software switchable x10 and x50 analog input multiplier and AC/DC coupling, switchable 50 ohm termination, a double speed built-in USB host interface all in a physical package about 2/3 the size and weight of BS300U.

BS325 with third party software

BS325 is user programmable, software extendable and can be integrated with third party software.

To make this easy the BitScope Library is available for BS325. The library can be used to create custom applications or to integrate one or more BS325 units into specialised testing and data acquisition systems.

The library is included as standard with BS325 and is compatible for Windows, Linux and Macintosh platforms.

Test and Measurement World

“Bill & Dave” takes you through not only the history of the Hewlett-Packard Company, it gives you insight into how the company’s founders thought and acted. Malone particularly points to how Hewlett and Packard dealt with people. He cites many “war” stories, starting at Stanford, through World War II, when Hewlett left the fledgling company for Packard to run, and onward through Packard’s death in 1996 and Hewlett’s death in 2001.”

“RMS to DC conversion is the truest way to measure the energy contained in an AC waveform.”

The accurate measurement of AC for a wide variety of waveforms and noise is difficult. When we make solar systems and inverters, the AC outputs are seldom sinusoidal. The easy method is to use a Precision rectifier/filter, get the average voltage and a RMS calibration/scaling is done for sine is by tweaking a trimpot. This will not show the right values for other waveforms. The other way was, analog computing, with many opamps and a matched pair of transistors; like multipliers and log amps, very cumbersome for manufacturing and testing.

These single chip solutions like LTC1968 – Precision Wide Bandwidth, RMS-to-DC Converter make it easy to implement an AC Measurement in your embedded, PLC or PC based solution.

Community College Education Resource

These pages have NDT study material for college and Science Educational Pages for High School.

Students can get ideas for original project work on one of these concepts. Choose one area and then research in the web. When i had to build Equipment, it would be difficult to get the catalogs and datasheets of Materials or Methods. Now master the art or searching online, then create your database.
