10.5 Ambient Temperature (Type U)
Allowable ambient temperature permitted for the sensor unit is as described in the table below.
(The following table describes the condition for the non-explosionproof models. For the explosionproof
models, make sure to satisfy the temperature conditions described in Section 10.4, as well as the
condition described below.)

Terminal box
Adapter
Heat insulation can be applied to
the sensor unit itself at the fluid
temperature. However, do not apply
heat insulation to terminal box or
adapter.
