Serial Number and Nameplate
Each actuator has a serial number. The serial number is a 10-digit number that begins with the
year and that can be read from the nameplate (see
Figure 9
) of the actuator (the nameplate is
located next to the handwheel – see
Figure 10
). Using this serial number, Emerson can uniquely
identify the actuator (type, size, design, options, technical data and test report).
