Connection data FHX50
• The device can be connected to a measuring device which has an intrinsically safe display circuit.
For more information see "Connectable transmitters" section.
Connectable transmitters
• To connect the device to a measuring device, such as a measuring device from Hauser, it must meet
the following conditions:
– The device has an intrinsically safe display circuit
– The device specifically bears the information "Prepared for display FHX50"
– The device is prepared for display FHX50 using the retrofit kit
Please note the "Connectable transmitters" section in the Special Documentation SD01007F provided!
Basic specification, Position 6 (Option Measurement Device) = A, B
• All transmitters for which the device structure provides the "Prepared for display FHX50" (A) option can be
converted using the retrofit kit (B).
Please note the "Extended order code" section in the Safety Instructions (XA) included with the transmitter.
The measuring device which has already been prepared for the FHX50 or converted using the retrofit kit has
an intrinsically safe display circuit with the following characteristic values:
