4. Design and function / 5. Transport, packaging and storage
4. Design and function
4.1 Description
The prevailing pressure is measured at the sensor element through the deformation of a diaphragm.
GB
By supplying power, this deformation of the diaphragm is converted into an electrical signal. The output
signal from the pressure transmitter is amplied and standardised.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation
site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: See chapter 3 "Specications"
WARNING!
Before storing the pressure transmitter (following operation), remove any residual media.
This is of particular importance if the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.

6. Commissioning, operation
WARNING!
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
Only use the pressure transmitter if it is in perfect condition with respect to safety.
6.1 Making the mechanical connection
■
The sealing faces at the instrument have to be undamaged and
clean.
■
When screwing the instrument in, the force required to do this must
not be applied through the casing, but only through the spanner ats
provided for this purpose and using a suitable tool.
The correct torque depends on the dimensions of the process
connection and the gasket used (form/material).
Maximum tightening torque
Process connectionTightening torque

GB
Tapered threads
per EN 837per DIN 3852-E
Correct sealing of the process connections with
parallel threads at the sealing face must be
made using suitable at gaskets, sealing rings or
WIKA prole sealings.
For further information on seals see WIKA data sheet AC 09.08 or at www.wika.com.
6.2 Making the electrical connection
■
The pressure transmitter must be earthed via the process connection.
■
Use the pressure transmitter with shielded cable.
■
Cables, connectors and terminating resistors which are used in a CAN network must comply with the
requirements of ISO 11898-2.
16WIKA operating instructions pressure transmitter, model MHC-1
For sealing process connections with tapered
threads, the sealing must be made in the threads
using additional sealing material, e.g. PTFE tape
(EN 837-2).
NPT, R and PT
14035467.01 08/2012 GB/D/F/E
6. Commissioning, operation
■
The bus cable must be terminated by means of a terminating resistor on both ends.
■
Keep stubs as short as possible.
■
In the instrument version with integrated Y connector, the bus signal and the power supply are
bridged internally from one connector to the other.
