Type 9301C ... 9371C Piezoelectric load cells, also known as force transducers or force links, measure dynamic or quasistatic forces, both ten- sile and compression. These load cells contain a piezoelectric ring force transducer of the 90x1C family: preloaded and cali- brated, thus ready to use immediately.

Description

The 93x1C load cell family is the easiest way to measure forces piezoelectrically without the need for sophisticated installation and calibration. The force transducers are factory calibrated and preloaded to measure both tension and compression forc- es. This means, that the sensor is ready to measure within minutes and provides accurate data from dynamic or quasi- static processes. In addition, the sensor has been installed in an electrically isolated manner, so that ground loops are largely eliminated. Application Quasistatic measurements are possible without any problems, but the 93x1C is mainly used where dynamic processes have to be recorded exactly. Due to the extremely high stiffness of the piezoelectric load cell, the elastic behavior of the measured object is practically unchanged. The force link comes calibrated in 3 different ranges and is im- mediately ready for use. Examples of Use Automobile industry

• Safety technology, monitoring of collision forces
• Mechanical shocks in chassis
• Forces on balancing machines Material testing
• Impact testing, alternate strength testing Machine tools
• Monitoring on presses, punching, embossing and welding machines
• Force measurements on longitudinal guideways Mounting and Force Introduction The mounting of these force transducers is quite simple, but nevertheless it should be done carefully and correctly:
• The contact surfaces must be flat, clean, parallel and as rigid as possible.
• The fixing screws must not touch the threaded base.
• The mounting screw must be tightened so that no gap is created at maximum tensile force. The force application should be as concentric as possible with the sensor axis. Eccentric force introduction, bending moments, torques and shear forces are only permissible up to a certain degree. For further details, please refer to the user manual. General machine building
• Monitoring of supporting forces (force oscillations) on machinery mounted on damping elements.
• Clamping processes, e.g. force sensor combined with hydraulic cylinder
• Joining technique (insertion, press fit of components) Quality control
• Force measurements on switches
• Monitoring of automatic assembly machines

The smaller the measuring range, the better the linearity and hysteresis. The piezoelectric force transducers 93x1C are preloaded with 60% of the nominal force of the 90x1C sensor built into them. This enables the measurement of equally large positive and negative forces. The lowest 20% of the nominal force range is not taken into account, since the susceptibility to moments, shear forces and non-linearities is highest there. The load cells 93x1C are calibrated in three different ranges: +100%, -100%, +1%. A detailed operating manual with further explanations of Installation, dimensioning and cabling can be found in the download area of our website www.kistler.com. Mounting Examples, Different Types of Force Introduction Example A Example B Example C Force introduction of compression forces. Loading from tensile and compression forces via an extension piece. The preloading force on the sleeve must not be less than a mini- mum value under the effect of tensile forces. Force introduction of tensile and compres- sion forces directly onto the threaded con- nection. In this case, a lock nut should al- ways be used. Example D Mounting example of a force link in a hy- draulic clamping device. Monitoring of ten- sile and compression forces. Example C

The force distribution cap helps to signifi- cantly increase the precision and repeatability of the measure- ment with an exactly defined point of force application. Flange If installation with the central bolt is not possible directly, the flange 9501Ax is installed. The precision part can be used for both compressive and tensile forces, as shown examples A...D on page 3.

Only high-insulation coaxial cables with low capacitance that produce only a very small amount of static electricity may be used as connecting cables for piezoelectric sensors. Kistler uses cables made of high-qua- lity PFA or oil-proof FPM here. On the sensor side, the IP protection class acc. to EN60529 is generally dependent on the used connector. For IP65, the standard 10-32 KIAG cable connector with knurled nut is used; for increased requirements in harsh environments, the industrial-suited 10-32 KIAG pos. int. version is used which, if necessary, can be tightly welded with the sensor case and IP68 achieved.
