DTI SERIES 2-WIRE DIFF. PRESSURE TRANSMITTERS – PRODUCT DATA & MOUNTING INSTRUCTIONS
SAFETY REMARKS
CAUTION!
Danger. Minor or moderately severe
The DTI pressure transmitter is used for measuring relative
(gage) pressure in liquids and gases. Improper application of
the device can be dangerous. The device is to be used only
by authorized and professionally qualified personnel who
follow these instructions and the relevant technical standards
and statutory regulations (depending upon the given ap-
plication) for installing, connecting, and operating the device.
This device does not meet the requirements for a "Com-
ponent with safety functions" as per the Pressure Directive
2014/68/EU.
The sample medium must not be allowed to freeze in the
pressure transmitter!
Functional earth (F.E.): The pressure transmitter must be
earthed via the process connection. Otherwise: See section "
Electrically Non-Conductive Process Connection."

Electrically Non-Conductive Process Connection
If the process connection is not electrically conductive and is
thus unsuitable for the required functional earth, the func-
tional earth can instead be effected via the plug connector
(see Fig. 3). In this case, however, the device must be
equipped with an electrical circuit that meets the requirements
of EN 61010-1 with regards to "Limited-energy circuits."

NOTE:
To ensure protection rating IP65, the plug con-
nector must be completely mounted – with the
gaskets included in the delivery (8) – and a cable
of appropriate diameter must be used.
