Measuring Ranges

1. Code 1 and 3 have multiple rangeswhich could be jumper sel ected.
2. Set the 5 engineering unitsby button keysand the related LCD indicator will be on.
3. For zero center models, add "Z" at the end of the model. For example,
the range is-30-0-30/-62.5-0-62.5pa. Only ranges 1~6 have thisselection.

RSA-TDPA-F Flush Mount Differential Pressure Transmitter
It's the combination of RSA-TDPA (with LCD) and flush mount panel
(model RSA-TDPA -A). The specifications are the same as RSA-
TDPA. And the model is RSA-TDPA -F xx1(with LCD). It's good for
flush mount in clean room or equipment with no dust and easy to
clean 316 brushed stainless steel panel, with the size
W104×H88×T1.5 and flush mount opening size W93
×H79×D42(mm).
