Assembling
The EX(M)637XYYYZ and EX(M)638XYYYZ Series have hermetically sealed stainless Steel housings, with a
glass-sealed connector, and do not require any assembly. Only mounting to the machine being monitored using
standard mounting accessories.
Dismantling
Other than removal from the mounting, there is no disassembly of the sensor required to take it out of service.
Maintenance
Routine maintenance, such as the cleaning of electrical connectors, housings, and mounting surfaces with solutions
and techniques that will not harm the physical material of construction, is acceptable.
Servicing
Due to the sophisticated nature of the sensors and associated instrumentation provided by PCB Piezotronics, user
servicing or repair is not recommended and, if attempted, may void the factory warranty. However, routine
calibration of sensors and associated instrumentation is recommended as this helps build confidence in
measurement accuracy and acquired data over time.
Repair
In the event that equipment becomes damaged or ceases to operate, arrangements should be made to return the
equipment to PCB Piezotronics for repair. User servicing or repair is not recommended and, if attempted, may void
the factory warranty.
Installation
Overview: Sensor must be mounted in order to be put into service. When choosing a mounting method, consider
closely both the advantages and disadvantages of each technique. Characteristics like location, ruggedness, amplitude
range, accessibility, temperature, and portability are extremely critical. However, the most important and often
overlooked consideration is the effect the mounting technique has on the high-frequency performance of the
accelerometer. Mounting methods include: Stud mount, adhesive mount, magnetic mount, or probe tip mount.
Cabling: Care and attention to cable installation and cable condition is essential as the reliability and accuracy of any
measurement system is no better than that of its weakest link. Due to the nature of vibration measurements, all sensor
cables will ultimately fatigue and fail. Good installation practice will extend the life of a cable, however, it is highly
recommended to keep spare cables on hand to enable continuation of the test in the event of a cable failure.
Adjustment
The sensor is a sealed device and no user adjustments are possible. However, routine calibration of sensors by the
manufacturer is recommended as this helps build confidence in measurement accuracy and acquired data.
Danger Areas (for
pressure-relief
devices)
N/A – not a pressure relief device.
Training
Instructions
Industrial sensors to be installed in Hazardous Locations must have this done by trained professionals according to
EN/IEC 60079-14 requirements.
Details on Safety
of Protection
Category
Ex ia is “intrinsic safety”, which limits the energy of sparks and surface temperatures to safe levels.
Ex nA is “Non-Sparking”, which ensures that there is no risk of arcing and sparking or hot surfaces during normal
operation with a minimum IP protection of IP54.

Special Conditions
of Use
Version Ex nA:
The apparatus must be only connect to an equipment whose electrical parameters are compatible with the electrical
parameters. The apparatus shall be connected according to drawing 70910 (page 2/2). The connected cable and the
connector must provide a minimum ingress protection of IP54, when assessed according to IEC 60079-0 and IEC
60079-15. Unused connector must be fitted with an appropriately rated blanking cover.
Device complies with the requirements of the dielectric test per clause 6.3.13 of standard IEC 60079-11.
