Repair and Maintenance 

 

 

PCB guarantees Total Customer Satisfaction through its 

“Lifetime  Warranty  Plus”  on all  Platinum  Stock  Products 

sold by PCB and through its limited warranties on all other 
PCB  Stock,  Standard  and  Special  products.  Due  to  the 
sophisticated  nature  of  our  sensors  and  associated 
instrumentation, 

field  servicing  and  repair  is  not 

recommended  and,  if  attempted,  will  void  the  factory 
warranty

 
Beyond  routine  calibration  and  battery  replacements 
where  applicable,  our  products  require  no  user 
maintenance.  Clean  electrical  connectors,  housings,  and 
mounting surfaces with solutions and techniques that will 
not  harm  the  material  of  construction.  Observe  caution 
when using liquids near devices that are not hermetically 
sealed.  Such  devices  should  only  be  wiped  with  a 
dampened cloth

never saturated or submerged.  

 

In the event that equipment becomes damaged or ceases 
to operate, our Application Engineers are here to support 
your  troubleshooting  efforts  24  hours  a  day,  7  days  a 
week. Call or email with model and serial number as well 
as a brief description of the problem. 

 

Calibration 

 

 

Routine 

calibration 

of 

sensors 

and 

associated 

instrumentation  is  necessary  to  maintain  measurement 
accuracy. We recommend calibrating on an annual basis, 
after  exposure  to  any  extreme  environmental  influence, 
or prior to any critical test.  

 

PCB Piezotronics is an ISO-9001 certified company whose 
calibration  services  are  accredited  by  A2LA  to  ISO/IEC 
17025,  with  full  traceability  to  SI  through  N.I.S.T.  In 
addition to our standard calibration services, we also offer 
specialized  tests,  including:  sensitivity  at  elevated  or 
cryogenic  temperatures,  phase  response,  extended  high 
or low frequency response, extended range, leak testing, 
hydrostatic  pressure  testing,  and  others.  For  more 
information,  contact  your  local  PCB  Piezotronics 
distributor,  sales  representative,  or  factory  customer 
service representative.  

 

Returning Equipment 

 

If  factory  repair  is  required,  our  representatives  will 
provide you with a Return Material Authorization (RMA) 
number, which we use to reference any information you 
have  already  provided  and  expedite  the  repair  process. 
This number should be clearly marked on the outside of 
all  returned  package(s)  and  on  any  packing  list(s) 
accompanying the shipment.
