- The device must only be used as described in this instruction manual. If used otherwise, this can cause dangerous situations for the user and damage to the meter.
- The instrument may only be used if the environmental conditions (temperature, relative humidity, …) are within the ranges stated in the technical specifications. Do not expose the device to extreme temperatures, direct sunlight, extreme humidity or moisture.
- Do not expose the device to shocks or strong vibrations.
- The case should only be opened by qualified PCE Instruments personnel.
- Never use the instrument when your hands are wet.
- You must not make any technical changes to the device.
- The appliance should only be cleaned with a damp cloth. Use only pH-neutral cleaner, no abrasives or solvents.
- The device must only be used with accessories from PCE Instruments or equivalent.
- Before each use, inspect the case for visible damage. If any damage is visible, do not use the device.
- Do not use the instrument in explosive atmospheres.
- The measurement range as stated in the specifications must not be exceeded under any circumstances.
- Non-observance of the safety notes can cause damage to the device and injuries to the user.
- Do not transport the force gauge when it is attached to the manometer as the manometer could detach and damage the force gauge.

General information
3.1 Applications
The hydraulic ring force gauges of the PCE-HFG series can be used variably
for measuring axial forces or bearing forces as well as vertical forces during
maintenance and adjustment work. The special feature of the force gauge is the
27 mm ring aperture with an axial screw mounting. With the ring aperture in
the force gauge, measurements can be made on guide rails, shafts and also
bolts of hydraulic presses, for example. With the insertable compression die
adaptor, the force gauge can be converted from a ring force gauge to a
compression die force gauge within seconds and used for measuring industrial
machines, for example. The force gauge can be used wherever applied forces are
to be measured. With its integrated drag indicator, the force gauge can save
the respective maximum measured value.
3.2 Operating principle
The force gauge works on the basis of the principle of force transmission. The
forces applied to the compression die can be measured and displayed via the
closed hydraulic system. The external forces generate a hydraulic pressure
inside the force gauge. The oil acts as a transmission medium and transmits
the forces to the manometer. On the manometer scale, these forces are
displayed in Newton. The test instrument is adjusted to the display by the
design of the housing and the compression die. Opening the closed hydraulic
system falsifies the measuring results and a new adjustment must be made.
Note: Make sure that the closed hydraulic system is not opened.
3.3 Force application
The hydraulic ring force gauges of the PCE-HFG series are only designed for
pressure forces perpendicular to the compression die. Any loading with
transverse forces, bending moments and torques can tilt or displace the
compression die and thus cause a permeability between the die and the
housing. In general, the higher friction results in a greater measurement
error.
Note: Avoid any loading with transverse forces, bending moments and torques.
The force gauge is used to measure static pressure forces. Dynamic forces can only be displayed at very low frequencies. The transducer should always be loaded and unloaded slowly. Ensure that the measurement range is generally not exceeded. Sudden pressure surges and over-range may destroy the manometer.
Note: Avoid sudden loading and unloading of the die.
System description
The hydraulic ring force gauges of the PCE-HFG series are available as four
versions. The versions differ in the measurement range, the unit of force
display and the scale resolution. Further information is explained in chart
2.2 Models.
The geometry is identical for all models.

4.2 Dimensions in mm
The dimensions apply to all models of the PCE-HFG series.
Operation
Due to the design-related frictional forces prevailing in the manometer and
the inertia of the indicator needle, measurements may be inaccurate.
Especially after a longer period of non-use of the hydraulic ring force gauge,
this inertia can occur at the indicator.
To ensure the accuracy of the measurement, load and unload the compression die
several times before measuring. You can eliminate any remaining inaccuracies
by “knocking” on the black housing of the manometer.
Maintenance
If the operating and safety instructions are observed, the force gauge is very
low-wear and does not require any maintenance over a longer period of time. To
achieve this, the force gauge must be protected from coarse contamination and
the closed hydraulic system must not be opened.
To check the measuring accuracy, however, the hydraulic force gauge must be
sent to the manufacturer at regular intervals (annually) for inspection and
recalibration.
Contact
If you have any questions, suggestions or technical problems, please do not
hesitate to contact us.
You will find the relevant contact information at the end of this user manual.
Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the
European Parliament applies.
Due to the contained pollutants, batteries must not be disposed of as
household waste. They must be given to collection points designed for that
purpose.
NOTE for the disposal of waste oil
Dispose of escaping oil via your local recycling centre.
In order to comply with the EU directive 2012/19/EU we take our devices back.
We either re-use them or give them to a recycling company which disposes of
the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in
accordance with your local waste regulations.
If you have any questions, please contact PCE Instruments.
