Impact Sensor

 

 
Polyimide  film  tape  covers  the  cap  surface  to  reduce  high 
frequency  ringing  associated  with  metal-to-metal  impacts.  
Internal  mounting  holes  with  uniform  10-32  threads  are 
prepared on each end of the sensor in the smaller models.  Two 
Model  081B05-mounting  studs  (M081B05  for  metric 
installation)  are  supplied.  Larger  ICP®  Models  200C20  and 
200C50,  as  well  as  charge  mode  model  210B50,  have  ¼-28 
mounting provisions and are supplied with ¼-28 stud both ends 
as well as a 1/4-28 to M6x1.0 for metric mounting. 
 
Versions  offering  full-scale  measurement  ranges  of  10  lb  to 
5000 lb compression (45 to 22kN) tension are available.  For 
higher ranges, consider the dedicated ring, link, or impact style 
sensor configurations.  
 
Applications include drop testing, machinery studies, punching 
and forming operations, tensile testing, fatigue testing, fracture 
analysis, and materials testing. 
 

RINGS 

Series 201B to 207C Ring Sensors are designed to measure 
compression forces from a fraction of a lb(N) to 100,000 lbs 
(to 444.8k N).   
 
Each sensor is provided with a calibration certificate reflecting 
the  sensitivity  of  the  sensor  when  calibrated  with  a  PCB 
supplied Beryllium Copper (BeCU)mounting stud. In the event 
a customer is going to install the sensor in a fixture without a 
mounting  stud  or  with  a  stud  of  a  stiffer  material  than  the 
supplied  BeCu  stud,  the  sensor  sensitivity  will  be  slightly 
different.

GENERAL PURPOSE - RADIAL 

Model 208C01-C05 General  Purpose Sensors are designed to 
measure  compression  and  impact  forces  from  a  fraction  of  a 
lb(N)  to  5,000  lbs  (to  22.24  kN).    Tension  forces  can  be 
measured  to  500  lbs  (2.224  kN).    Model  084A03,  a  supplied 
convex, stainless steel cap with integral 10-32 mounting stud, 
converts this tension/compression model to a sensor capable of 
impact  measurements.    Polyimide  film  tape  covers  the  cap 
surface to reduce high frequency ringing associated with metal-
to-metal impacts. 

 
GENERAL PURPOSE - AXIAL 

Models 208A11-A15  Axial Sensors provide performance and 
specifications  similar  to  the  Model  208C  Sensors.    These 
sensors  are  designed  primarily  to  measure  compression  and 
impact forces from a few pounds(N) to 5,000 lbs (to 22.24 kN). 
Tensile forces can be measured to 500 lbs (2.224 kN).  The 10-
32 axial electrical connector orientation associated  with these 
sensors makes them ideal for installations where radial space is 
restricted or where physical connector damage may occur due 
to  the  nature  of  the  specific  application.    The  M7  x  0.75-6g 
mounting threads (all models) may be installed directly into a 
test structure so that the 10-32 electrical connector exits from 
the  opposite  side  of  the  mounting  fixture.  This  helps  prevent 
potential  damage  during  drop  test  applications.    This  version 
also uses the Model 084A03 cap for impact measurements. 
 
Figure  5  outlines  some  possible  mounting  configurations  to 
which the ring series may be installed
