2. Important Notes

It is essential for you to study the following notes, which

are for your personal safety during work, and to ensure

long term, fault-free operation of this product.

2.1 For Your Safety

 This product has been thoroughly tested and has left

the factory in a perfectly safe condition. In order to

maintain this condition and ensure safe operation, com-

pliance is required with the instructions and warning

notes in this instruction manual.

 The 2-component sensor must be installed, operated

and maintained only by persons who are familiar with

this product and who are adequately qualified for the

work involved.

 If it is to be assumed that safe operation is no longer

possible, the equipment must be shut down and made

safe against being accidentally started up.

Safe operation must be assumed to be no longer possi-

ble when

 the 2-component sensor shows visible signs of dam-

age,

 the 2-component sensor has been overloaded,

 the 2-component sensor is no longer operating,

 has been in lengthy storage under unsuitable condi-

tions and,

 has been subjected to rough transport conditions.

Install the 2-component sensor in position as prescribed.

Details can be found in Section 4.2.

Secure all parts mounted on the 2-component sensor

according to anticipated moments!

Page 6 9345B_002-553e-03.23

2.2 Unpacking

Check all packaging for transport damage. Report any such

damage to the transporters and to the authorized Kistler

distributor.

Check accessories delivered (see Section 8.5) before first

use of the equipment. Report any missing parts to the au-

thorized Kistler distributor.

2.3 Notes on Using the 2-Component Sensor

 The 2-component sensor must be used only under the

environmental and operating conditions specified.

 With piezoelectric sensors, insulation resistance is of

crucial importance; it must be approx. 5·1013 Ω (but not

less than 1013 Ω).

 In order to preserve this value, all plug-and-socket con-

nections must be kept absolutely clean and dry. The in-

sulation resistance can be measured with the insulation

tester Type 5493.

 Protect the connector of the 2-component sensor

against contamination and do not touch it with your

fingers (connector front). Fit the cover supplied over the

connector when it is not in use.

 A high-insulation cable is used to connect the

2-component sensor to a charge amplifier. Once at-

tached, it should if possible remain connected to the

sensor. Use only specified connecting cables.

 Protect the 2-component sensor when it is not in use by

storing it in its original packaging.

General Description

9345B_002-553e-03.23 Page 7

3. General Description

3.1 What is the Purpose of the 2-Component Sensor?

2-component sensors are used to measure dynamic and

quasistatic torques.

The 2-component sensor measures forces as well as mo-

ments. Therefore it is possible to record a second process

value at the same time or successively.

The main areas of application are:

Calibration

 Calibration of manual torque wrenches

 Torque setting of pneumatic screwdrivers

Research and Development

 Measurement of irregular motion and torsional

vibrations on small servo and stepper motors

 Measurements of starting torques on electric motors

 Measurements on fluid and slipping clutches

 Viscosity measurements

 Measuring the coefficient of friction of bearings

 Designing torsion springs and damping elements

 Development of locks and rotary switches

 Lubricant development

 Biomechanics and ergonomic measurements

Production Engineering

 Monitoring automated screwing processes

 Monitoring boring and cutting processes

Quality Control

 Testing screw connections

 Torsion testing of springs

 Testing the torque characteristics of hinges

 Testing rotary switches

 Testing of screw caps

The hole pattern of the bilaterally integrated flange and the

optional accessories enable Kistler 2-component sensors to

be adapted to almost any task. Bilateral centering seats and

the included centering rings assist in the precise axial appli-

cation of torque. A centric bore can be used for shaft bush-

ing.

Kistler 2-component sensors are distinguished by high

rigidity and a high natural frequency. The effective useful

frequency range is, however, determined by the natural

frequency of the entire test arrangement. The high resolution

enables the tiniest dynamic changes to be measured, even

where large torques are involved.

Kistler 2-component sensors are calibrated prior to

delivery and can be used immediately.

Page 8 9345B_002-553e-03.23

3.2 Design and Functional Principle of the 2-Component Sensor Type

9345B and 9365B

The special patented design of Kistler 2-component sensors

is characterized in that the sensor is axially preloaded. Par-

ticularly in the case of small forces and moments, this pre-

loading of the sensor is a requirement for good linearity of

the output signal.

The 2-component sensor is rust-resistant, welded seal-tight

and the connection with a cable connected is protected

against the ingress of water spray (Condition: O-ring cor-

rectly located in the cable connector). In addition, the con-

nector is protected against mechanical damage by the con-

nector protector Art. No. 3.414.366 which is included.

The 2-component sensor contains a ring-shaped pair of

quartz crystal plates as an integrated sensor element sensitive

to pressure. The pressure-sensitive direction of the crystal

plates is arranged so that a charge signal proportional to the

magnitude of the compressive force is produced.

In addition there are quartz disks in a circular arrangement

built in. The shear-sensitive direction of the quartz disks is

tangential, so that a charge signal proportional to the

torque is fed out in a parallel circuit.

A negative charge produces a positive voltage at the out-

put of the charge amplifier and vice versa.

Measurement is made practically without displacement as a

result of the piezoelectric measuring principle and the high

rigidity of the 2-component sensor.

4. Installation and Startup

4.1 Important Information

The 2-component sensor Types 9345B and 9365B are pre-

cision instruments whose specifications are fully utilized on-

ly when they are correctly employed and only when they

are carefully handled. Please comply with the following:

 Never let the 2-component sensor drop or expose it to

hard impacts! The peak force of such a shock can cause

irreparable damage.

 Do not use a hammer to position the work pieces, as

impacts of this kind can also cause damage!

The following sections will provide you with information on

how to mount the 2-component sensor and on setting up a

measuring chain.

4.2 Installation of the 2-Component Sensor

Please comply with the following information con-

cerning the correct mounting of the 2-component sensor:

 The 2-component sensor must be installed only by per-

sons who are familiar with it and are adequately quali-

fied for this work.

 Angular seating will cause unwanted bending moments

which can overload and even destroy the sensor. The

contact surfaces of adapter flanges must be machined

perfectly flat. If the 2-component sensor is used as a

calibration element, the adjoining surfaces must have a

roughness of Ra ≤0,8 µm (N6), otherwise a roughness

of Ra ≤6,3 µm (N9) will suffice. Before mounting, the

contact surfaces must be thoroughly cleaned.

 The 2-component sensor is designed for measuring forc-

es in the longitudinal axis as well as Moments on the ax-

is. Although additional bending moments, tensile, com-

pressive and shear forces can be tolerated by the

2-component sensor up to a certain extent, these should

be avoided if possible.

2-Component Sensor Fz, Mz, Type 9345B, 9365B

Page 10 9345B_002-553e-03.23

The force and moment must only be applied by the flange

surfaces at the top and bottom sides of the 2-component

sensor. The force is thereby transferred via the front-side

flanged-on adaptation parts (strength class at least 12.9) or

mounting parts with appropriate contact sur

faces. The

length of the screws must be selected so that the depth of

the blind hole in the 2-component sensor flange is fully

utilized. The screws must not, however, protrude against

the base of the blind hole.

Installation and Startup

9345B_002-553e-03.23 Page 11

When firmly tightening the screw connections, the fork

wrench must only be used to hold the flange on that

side where the screw connections are being tightened!

If the opposite side is held, there is a risk that the screw

connection in the 2-component sensor will loosen caus-

ing

the latter to turn within itself. This will alter the

internal preload resulting in the calibration being lost,

and possibly rendering the 2-component sensor unusa-

ble for precise torque measurement! In this event, the 2-

component sensor must again be properly preloaded and

recalibrated!

Tightening Torques MA for Fillister-Head Screws

Type 9345B M5x12 MA = 4 N·m

Type 9365B M8x20 MA = 21 N·m

We recommend the use of screws from the strength class

12.9 upwards.

The connecting cable must be connected only after the

2-component sensor has been installed. Since contamina-

tion on the connector contacts can lead to sizeable measur-

ing errors (in particular drift), the plastic protective connector

covers on the sensor as well as on the cable should always

remain screwed in position during mounting! In particular,

the greatest care must be exercised in dirty environmental

conditions.
