3.1 In-head transmitter
The transmitter is intended for installation in DIN B connection heads or larger. The large
Ø7 mm / 0.28 inch center hole facilitates the electrical connection of the sensor and the
installation. For detailed information refer to
Dimensions on page 46.

INFORMATION!
The connection head installation kit does not belong to the standard scope of delivery of the
transmitter, you have to order it separately.
DANGER!
The transmitter is optionally available in an intrinsically safe version (zone 0, 1 and 2) for
installation in potentially explosive atmospheres. The intrinsically safe version must be supplied
by an intrinsically safe power supply unit or Zener barrier placed outside of the potentially
explosive zone. The Ex transmitter must be installed in a housing with the protection rating IP20
or better according to EN 60529 / IEC 60529.
WARNING!
The transmitter has been developed for an operating temperature of -40...+85
°
C/ -40
°
F...+185
°
F.
To avoid destruction or damage of the device, always assure that the operating temperature or
ambient temperature does not exceed the permissible range. The thermowell also transfer the
process temperature to the transmitter housing. If the process temperature is close to or
exceeds the maximum temperature of the transmitter, then the temperature in the transmitter
housing can rise above the maximum permissible temperature. One way to decrease the head
transfer via thermowell is to install the transmitter further away from the heat source. Inversely
similar measurements can be done if the temperature gets below specified minimum
temperature.
