1 Tasks and Functions of the HMG 3000
The HMG 3000 portable data recorder is a hand-held unit for simple measurement and data
capturing tasks involving hydraulic and pneumatic systems. Applications extend primarily to
maintenance and servicing, troubleshooting and test rigs.
The HMG 3000 can concurrently evaluate signals from up to 10 sensors. The unit features
input jacks for connecting the sensors; if necessary this number can be doubled using a
adapter for measurement operations involving more than 5 sensors. HSI sensors (HYDAC
Sensor Interface) are HYDAC sensors for pressure, temperature and flow rate with automatic
sensor recognition.
You also have the option of connecting SMART sensors to the HMG 3000. These are the
new generation sensors from HYDAC, capable of outputting several different measured
variables. These sensors are also automatically recognized by the HMG 3000 via HIS, and
the measured values including the measurement unit are shown in the display.
The HMG 3000 can render up to 32 measurement channels.
Depending on the sensor type the sensor features an internal memory providing for the
storage of recorded measurement data on a long-term basis. In addition, depending on the
sensor type preset parameters can be changed and stored in the internal memory as a
sensor configuration.
Older model HYDAC sensors or standard sensors of other manufacturers commercially
available can also be used. However, these sensors do not feature any automatic sensor
detection, consequently the initial set-up has to be entered by hand.
The HMG 3000 is user-friendly by virtue of its easy-to-access selection menus leading to all
of the unit’s functions and settings. The unit features a combination keypad for entering
numeric values and text in a fashion similar to that of mobile phones.
The HMG 3000 was designed in particular for capturing typical measurement values
(pressure, temperature, volumetric flow rate) in hydraulic and pneumatic systems. A
variety of other measurement tasks can be performed by virtue of additional inputs for
voltage measurement. Example: checking the actuation of a switching valve or plotting
the characteristic curve of a valve setpoint. In addition, it is also possible to determine
differential values between the measured values of individual sensors. One example of
this is taking a volumetric flow measurement using a differential pressure orifice plate.
In addition to the analog measurement inputs, the HMG features two digital outputs, enabling
frequencies or speeds to be recorded, thus expanding the unit’s range of potential
applications.
When taking measurements of rapid, dynamic machine processes, all 8 analog input
signals can be concurrently captured at a rate of 0.5 ms.
