7. Special conditions of use
7.1.
Y237
can ONLY be mounted on instruments manufactured by Dresser Produits Industriels S.A.S.
7.2. For ambient temperature greater than 70°C, the user must choice a cable entry and a cable
compatible with:
Ambient Temperature
Cable Temperature
75°C
80°C
80°C
85°C
85°C

7.3. Y237 is intended to be used in an ambient temperature from -55°C to +85°C.
7.4. The cable entry and the cable must be compatible with the minimum temperature of -55°C.
7.5. If a cable input from the
Y237
adaptor is not used, the hole must be closed by a plug, depending on
the size of the tapping involved.
7.6. In case of two cable gland entries not used, the
Y237
must be removed.

Y237
.
7.8. Adaptor or reducer are not allowed.
7.9. The external thread (male) shall be cemented with high-strength threadlocker type Loctite 2700 or
equivalent product with similar efficiency to secure the
Y237
in the intended direction.
