Measuring Technique


Patrick the particle counter

Patrick is an optical particle monitor working according to the light-extinction principle. It can be used to monitor the impurity level and the purity trend of liquids very accurately. The purity classes can either be displayed according to ISO4406:99 or SAE AS4059E. The data transfer can be managed flexible via CAN or RS 232. If your PC does not have a RS 232 interface, you can transfer the data with an USB-to-RS232-adaptor.

Patrick enables diagnosis and controlling of the quality of the oil of hydraulic systems. As a condition monitoring instrument, it completes the product portfolio from Hydrotechnik. Condition Monitoring is the supervision of the status of a machine or plant, to draw conclusions on the demand for maintenance or repair measures from the changing of certain parameters. This allows planning such measures exactly and possibly reducing downtimes significantly. 

Software for Measuring units


For the application of the instruments with data processing, Hydrotechnik develops its own software in-house. With HYDROcenter, HYDROcom6, HYDROlink, HYDROgen, HYDROrun as well as HYDROboot, Hydrotechnik supports you in achieving your measurement requirements.

From the data analysis, over remote control to your instrument, up to programmed test procedures, Hydrotechnik offers you the right product for your application. Besides the mentioned examples, Hydrotechnik software products offer a huge range of functions which save time and money. 

Minimess program

The name of the product line, Minimess, comes from the Hydrotechnik in-house invention, the Minimess® test point. This coupling builds up an interface to a running hydraulic system.

According to the test point, Hydrotechnik offers a huge portfolio of high pressure hoses with diverse kind of fittings, as well as gauges. Analog and digital gauges are available within a set, but also separately. Special versions of the test point for gas applications complete the portfolio of Hydrotechnik.

Hydrotechnik is the inventor of the Minimess®-test point – nothing is better than the original.

Sensors for different measurement categories

The success of a measure depends on the reliability of the data collection. The HySense® sensors by Hydrotechnik stand for quality and reliability. They are available for diverse measuring ranges, e.g. pressure, temperature, flow and other variables. 

Abbreviations for Product Names:

The two first letters at the beginning of the sensor’s name explains the measurement category:

PR = pressure

TE = Temperature

QT = Q= formula symbol of flow, T = Turbine

QG = Q= formula symbol of flow, G = Gear Flow Meter

QO = Q = formula symbol of flow, O from the Oval wheel

QL = Q = formula symbol of flow, L= Load

PS = P= Pressure, S = Switch

RS = R= Rotation Speed

TQ = Torque

TP = T= Temperatur, P= Pressure

PO = Position
