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.)
