Strain sensor takes electronics onboard
The Type 9234A piezoelectric strain sensor has an integrated charge amplifier with remote control of measuring range and provides an analogue output voltage of +/-10V.
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

Sensor measures mould cavity pressure indirectly
Cavity pressure is usually measured with the sensor fitted directly in the mould cavity, but Kistler's new PinSens force sensor type 9204 is ideal for indirect cavity pressure measurement
Melt pressure sensors aimed at extrusion process
The Kistler melt pressure sensors, types 4086/87A and 4096/97A, are designed for measuring pressure in the extrusion process.
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 measured.
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 quasistatic 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 newtons or kilonewtons.
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.
