Wiring diagram
Functional principle
Signal processors not only supply insertion
and inline sensors with voltage, they also pro-
cess and display the measured signals. De-
vices with MK96…, MS96… and MC96…
housing styles are available. The individual
housing styles are designed for different oper-
ating voltages and feature various output and
supplementary functions. For intrinsically safe
flow sensors it is required to use signal pro-
cessors with intrinsically safe control circuits
of the series MS96…Ex… and MC96…Ex… .

In order to ensure correct operation to the intended purpose it is required to observe the national regulations and directives.
For use in explosion hazardous areas conform to classification
II 1 G (Group II, Category 1 G, electrical equipment for gaseous atmospheres).
Marking (see device or technical data sheet)
É II 1 G and EEx ia IIC T6 acc.to EN50020 and EN50284
Local admissible ambient temperature
-20…+60 °C
Installation / Commissioning
These devices may only be installed, connected and operated by trained and qualified staff. Qualified staff must have knowledge of protection
classes, directives and regulations concerning electrical equipment designed for use in explosion hazardous areas.
Please verify that the classification and the marking on the device comply with the actual application conditions.
This device is only suited for connection to approved EExi circuits acc. to EN500014 and EN50020. Please observe the maximum admissible
electrical values.
After connection to other circuits the sensor may no longer be used in EExi installations. When interconnected to (associated) electrical equip-
ment, it is required to perform the "Proof of intrinsic safety" (EN60079-14).
Installation and mounting instructions
Avoid static charging of cables and plastic devices. Please only clean the device with a damp cloth. Do not install the device in a dust flow and
avoid build-up of dust deposits on the device.
If the devices and the cable could be subject to mechanical damage, they must be protected accordingly. They must also be shielded against
strong electro-magnetic fields.
The pin configuration and the electrical specifications can be taken from the device marking or the technical data sheet.
In order to avoid contamination of the device, please remove possible blanking plugs of the cable glands or connectors only shortly before in-
serting the cable or opening the cable socket.
service / maintenance
Repairs are not possible. The approval expires if the device is repaired or modified by a person other than the manufacturer. The most important
data from the approval are listed.
