ASSEMBLY
N.B.: the operations must be performed, if possible, when the machine is OFF and by using the
maximum delicateness in order to avoid any transmitter damages.
1) Predispose a special threaded hole on the support to be measured. The surface on which the
transmitter lies must be flat and smooth. It is better to interpose a silicon layer between the
transducer and the support surface.
N.B. : Avoid giving violent shocks to the transmitter body, the closure torque must be 5 to
10 N-m.
2) Connect electrically the transmitter to the measuring equipment through the movable connector
(included).
Notes for connection:
- The wiring MUST be made by using a cable, resistant to working environment agents (oils,
corrosive acids, temperatures, etc.).
- A shielded cable MUST BE used, bearing in mind that the screen must be connected to the
frame mass (GND=ground) at only one of the two cable ends (recommended instrumentation
side).
Notes for certification:
- The use of ATEX certified transmitters is not allowed for different hazardous conditions or
for those exceeding the data specified on the nameplate affixed to the transmitter.
- The transmitter does not require maintenance. Any work regarding performance checks or
repair should only be carried out in a laboratory duly authorized by CEMB S.p.A.
