The transmitter is, in combination with a sensor, used for measurement of mass
flow and data transmission.
The electrical circuitry of the transmitters is mounted inside a metal enclosure
which is divided into three compartments.
In one compartment (electronic compartment) the EMI Terminal Board, Power
Supply Board, Feature Board, Core Board and Backplane Board are mounted.
When executed with display, there is a window cover available, either marked (for
gas application) as IIB + H
5700*15**VA***).
The other compartment (terminal compartment) is equipped with terminals for
the connection of I/O signals and power.
The enclosure can be constructed with a terminal compartment (compartment
for sensor connection) for the connection of remotely operating intrinsically safe
sensors, type 5700C1***VA*** for a 9 wire connection, or type
5700R1***VA*** for a 4 wire connection.
Alternatively, the enclosure can be mounted directly to the sensor via a transition
compartment (type 5700I1***VA****). This type of mounting has to be certified
separately.
The enclosures (electronic compartment, terminal compartment and
compartment for sensor connection) also fulfil the requirements for type of
protection "Protection by enclosures". The transmitter is intended to be used in a
hazardous dust environment without change to any of the electronics aspects of
the design.
