CONSIDERATIONS
General
Electrical vibration sensors such as accelerometers produce low-level signals
proportional to their sensed vibration. With simple HART configuration, the
CSI 9420 converts the low-level sensor signal to a wireless-enabled signal.
Commissioning The transmitter can be commissioned before or after installation. It may be
useful to commission it on the bench, before installation, to ensure proper
operation and to become familiar with its functionality. When applicable, make
sure the instruments are installed in accordance with intrinsically safe or
non-incendive field wiring practices. The device will be powered whenever the
power module is installed. To avoid depleting the power module, make sure it
is removed when the device is not in use.
Mechanical Location
When choosing an installation location and position, take into account the
need for access to the transmitter. For best performance, the antenna should
be vertical with some space between objects in a parallel metal plane such as
a pipe or metal framework, as the pipes or framework may adversely affect
the performance of the antenna.
