Versatile Strain Sensor with integrated
electronics and remote control.
The new Type 9234A piezoelectric strain sensor from
Kistler Instruments has an integrated charge amplifier
with remote control of measuring range and provides
an analogue output voltage of ±10V.
Each of two measuring ranges can be adjusted to a particular
value or signal curve in one hundred steps using either a dedicated
remote control unit or directly by the machine's own PLC. When
the measuring range is adjusted, the setting is stored by the
integral electronics. The range can be switched remotely, even
under load conditions, enabling very low forces to be accurately
Typical applications for the sensor are monitoring C-frame machine
tools such as presses and automatic assembly machines, preventing
overload of mechanical presses, quality control of riveting, clinching
and resistance spot welding processes and detection of tool breakage
or collision in a wide variety of machine tools.
Secured to a suitable clean, unpainted position on the machine
frame by a single M6 screw, the sensor is especially easy to retrofit
to almost all types of machine tools. The sensor measures dynamic
and quasi-static stresses on machinery or structural surfaces using
indirect force measurement. The signal can be further processed
as a relative value or the sensor can be calibrated against an
appropriate standard to provide absolute measurements in N or kN.
Cable connection is by an M12-8-pin socket mounted either on the
end or upper face of the sensor using screened cables available
with straight or right-angled connector.
Although designed for real world, industrial applications, the new
strain transmitter is equally suited to research and development
applications requiring ease of installation and precision combined
with versatility and reliability.
