Applications to solve measurement problems

In the past decades, we have gained a lot of experience with different measurement problems. To better serve you, we have written a supporting article for you, for a large number of applications. Yhis way, you can get acquainted with our experiences in this area.

The articles, like the rest of the website, are subdivided into applications within the different divisions. We would like to ask you to check whether your application is listed or simply contact us to see if we can provide support for your application.


Use of N4L PSM series with Linear Variable Differential Transformers

An LVDT (Linear Variable Differential Transformer) consists of a transformer with one primary winding, two secondary windings and a movable fixture. With the primary winding at the desired voltage and frequency, the size and relative phase of secondary winding changes as soon as the luminaire is moved.

There are two ways to detect the relocation: ratiometric and differential. This is what the N4L application note below is about.

Testing of communication transformers with N4L PSM units

The PSM units from N4L are very suitable for manual or automatic testing (using a PC) of transformers. They have the measurement capability (DFT and true rms, of 10mHz to 2.4MHz) to carry out the most commonly required transformer tests, namely:

  • turns ratio
  • primary inductance and resistance
  • leakage inductance
  • interwinding capacitance
  • magnetising current
  • insertion loss
  • return loss
  • harmonics
  • thd
  • longitudinal balance

Most tests require a simple circuit, such as resistors to be mounted in a test fixture. The abovementioned tests can be found in the application note below.

Water treatment and electrolysis

A variety of water treatment processes requires DC power supplies to generate an electric field. For this the output of the power supply will be connected to the electrodes in a water tank, creating a closed circuit.

The specific properties of the power supply ensure maximum control of voltage and current, guaranteeing a constant process control. Magna-Power’s power-operated DC power supplies increase reliability during this process.

I have been doing business with TTMS for years. They offer us good advice, and have a wide range of products to choose from. Before we decide to purchase a product, TTMS allows us to use a demonstration model to experience for a few days whether the product meets our expectations. They think along with us and don't try to sell me just anything. Should it occur, for whatever reason, that there is a defect in the equipment of TTMS, they will follow up with the required service with regard to repair and, if necessary, a replacement. With its service, TTMS invests in a good and lasting customer relationship.
