Automatic process analyser - CE marked



Determination of Pour Point of petroleum products, diesel, gasoil, motor and engine oils, additives, lubricating oils, completely on line, full automatically, extremely accurately and fast with the New-on-line 300.


The New-on-line 300, making part of the new generation of on-line process analysers, determines Pour Point in correlation to the norms, while guaranteeing:


Perennity: conceived in order to have a raised longevity thanks to the good quality of the mechanical, electric and electronic components used for its manufacturing.

Simplicity: a modular architecture of design.

Supervision: accessible by Ethernet network on site or by safe remotely connection made by Internet.

Access for user and/or manufacturer

Conviviality: with a clear and didactic graphic interface.


This design brings a maintainability never reached on these analysers and in particular on the Pour Point Analysers which don’t require a particular maintenance. New-on-line 300 determines the Pour Point in correlation to the ASTM, IP, ISO, DIN standards by using technologies of on-line processes. With a reduced time of analysis (10 - 40 minutes) it allows a constant control in real time of the lines of production. The management of the analyser is completely automatic thanks to the dedicated software which allows the user to supervise and visualize all the parameters referred to the analysis in progress.


Determination of pour point is made by a precision pressure sensor that measure constantly the differential value during the test. The analyser, by means of the Lin–Tech software, observes and manages the phenomenon. As soon



This analyser consists a pressurised enclosure, EEx p for zone 1 and 2, with a CENELEC, ATEX certification and different accessories fixed on both sides of the enclosure.


The protecting system and some EEx d boxes are fixed on the left side, and the analytical part fixed on the right side.


In the upper part of the enclosure accessible with a door supporting a flat screen, are enclosed, the PC, the electronic, the interfaces and the interlock with the terminals.


This analyser is supplied with some components for the sample conditioning procedure. In option, a complete sampling conditioning system dedicated to a user application can be supplied.


This analyser has been designed to follow the reference standards methods.

The analytical cell is cooled down with Peltier elements.


This type of analyser has a main application in production unit where the sample composition does not change rapidly in a short period of time.


Principle of Detection

The detection consists in a constant reading of differential value of a precision pressure sensor.


The position of the sensor allows the system to observe the reducing flow inside the test tube.


The signal is recorded and after mathematical treatment, the value of the temperature of the Pour Point is displayed.


Due to the dynamical calculation, the main features of the sample has no effect on the detection. as the result is obtained, the cell is emptied automatically and a new cycle of analysis starts.


Procedure of Analysis

  • The application software proceeds to the draining first, by flushing the sample to the drain.

  • This operation takes a few seconds.

  • The second step is to fill the test tube on a time basis.

  • When the time of filing is elapsed, a seconde draining procedure can be done if necessary.

  • Then the analysis is started.

  • All this procedure of draining and filling takes 5 to 20 seconds depending on the selection made in the set-up software.

  • The analysis time will takes lower than 10 minutes up to 40 minutes.

  • The user can select the mode of analysis and also can do alternatively both methods.

  • The analyser can select a reference sample from one external drum to proceed to the validation of the analyser himself, before to start the analysis on the product line.This type of analyser is specially designed for production unit where the results have to has close as possible of the ASTM reference result from the laboratory.
