Safety instructions
1.1
Designated use
The heating jacket serves to transfer heat to maintain temperature of fluids in the Promass sensors
of the M, E, A, H, I, S and P design
Resulting from incorrect use or from use other than that designated, the operational safety of the
measuring devices can be suspended. The manufacturer accepts no liability for damages being
produced from this.
1.2
Installation, commissioning and operation
Installation, commissioning and maintenance of the instrument must be carried out exclusively by
trained specialists authorised by the facility’s owner-operator. The specialist must have read and
understood these Operating Instructions and must adhere to them
The manufacturer reserves the right to modify technical data without prior notice.
Your Hauser distributor will supply you with current information and updates to these
Operating Instructions.
1.3
Operational safety
Note the following points:
• Heating jackets can not be combined with sensor which have purge connections and/or rupture
disks.
• When using heating jackets, it is recommended to use the remote version of the sensor and
transmitter.
• When using the remote version at very high fluid and heating temperatures, we recommend the
use of the "long-necked version" (= remote version for heating), so that the ambient temperature
of the connection housing and the connecting cable is not exceeded.
• With the compact version, make sure you take appropriate measures (orientation, etc.) so that the
maximum ambient temperature for the transmitter is not exceeded, otherwise electronic
components will be driven outside their specifications. You should particularly avoid this for
components which are used for explosion protection.
• The permitted pressure of the heating medium is specified on the nameplate
→
Page 6.
• Heating mediums are acceptable, water, water vapour, and other non–corrosive liquids.
If using oil as heating medium consultation is to be held with Hauser.
• Deposits by dirty heating media or calcareous water can limit an even distribution of the heating
medium in the heating jacket. A faultless function of the heating jacket will not be then ensured.

Warning!
Danger of injury/burning from hot surfaces!
During operation, the surfaces of the heating jacket and those of the conveyance lines for the heating
medium may become very hot and will lead to burns if touched.
The customer is responsible for mounting insulation.
If the heating jacket and the conveyance lines are insulated, you must wait a long enough period of
time for the jacket to cool after the insulation is removed.
