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.

• Calibrated and ready to use

• Simple installation

• Centering seats for exact installation

• Ground-isolated

• Accessories for optimum force introduction

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
