MESO-H is the standard In-head transmitter and MESO-L is the DIN Rail
transmitter.
MESO-HX is the Intrinsic Safe In-head version for use in Ex-applications.
MESO-H, MESO-L and MESO-HX are fully HART-compatible, with
communication through the HART protocol, directly on the 4-20 mA
output loop.

CONFIGURATION

Conguration of the MESO transmitter is performed by using either a
general hand-held HART Communicator or a PC with the Inor Windows

software, MePRO 2, installed. Also Emerson AMS and Siemens PDM can

be used for conguration since the MESO transmitters are integrated into

them.
The MESO transmitter uses all HART

Common Practice Commands

the following numbers are used: 34, 35, 38,

40, 41, 42, 48, 49 and 59. These commands can be reached from a stan-

dard HART Handheld Communicator or a universal HART PC software and
HART PC modem.
Several

Transmitter Specic Commands

be read/written by a HART Handheld Communicator with the INOR MESO
DD included or via the Emerson AMS or Siemens PDM with the MESO DD
included.
To address all the features in MESO including the

tion

and the

Basic Calibration

the MePRO software must be used. The latest
version of the INOR PC software MePRO can be downloaded from http://

www.inor.com. Also a HART PC modem connected to the serial port or the

USB port of the PC is needed. For connection of the HART PC modem to
the transmitter see gures 10 – 12. The modem is connected over the load
(B-C) or over the transmitter (A-B).
For HART communication to work properly the MESO transmitters must
be powered and there must be at least 250 ohm in the current loop. To
communicate with the transmitter when it is installed in the eld, load re-

sistance, cable resistance and cable capacitance must be considered. See
diagram 3.

PLEASE NOTE! For MESO-HX make sure to follow the

instructions for maintaining intrinsic safety during con-

guration, installation and operation.

LIMITED WARRANTY

INOR Process AB, or any other afliated company within the Inor Group (hereinafter jointly referred to as

”Inor”), hereby warrants that the Product will be free from defects in materials or workmanship for a period

of ve (5) years from the date of delivery (”Limited Warranty”). This Limited Warranty is limited to repair
or replacement at Inor’s option and is effective only for the rst end-user of the Product. Upon receipt of

a warranty claim, Inor shall respond within a reasonable time period as to its decision concerning:

1 Whether Inor acknowledges its responsibility for any asserted defect in

materials or workmanship; and, if so,

2 the appropriate cause of action to be taken (i.e. whether a defective

product should be replaced or repaired by Inor).

This Limited Warranty applies only if the Product:

1 is installed according to the instructions furnished by Inor;
2 is connected to a proper power supply;
3 is not misused or abused; and

4 there is no evidence of tampering, mishandling, neglect, accidental damage, modica-

tion or repair without the approval of Inor or damage done to the Product by anyone
other than Inor.

This Limited Warranty is provided by Inor and contains the only express warranty provided.

INOR SPECIFICALLY DISCLAIMS ANY EXPRESS WARRANTY NOT PROVIDED HEREIN
AND ANY IMPLIED WARRANTY, GUARANTEE OR REPRESENTATION AS TO SUITA­BILITY FOR ANY PARTICULAR PURPOSE, PERFORMANCE, QUALITY AND ABSENCE
OF ANY HIDDEN DEFECTS, AND ANY REMEDY FOR BREACH OF CONTRACT, WHICH

BUT FOR THIS PROVISION, MIGHT ARISE BY IMPLICATION, OPERATION OF LAW,
CUSTOM OF TRADE OR COURSE OF DEALING, INCLUDING IMPLIED WARRANTIES
OF MER-CHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. EXCEPT AS
PROVIDED HEREIN, INOR FURTHER DISCLAIMS ANY RESPONSIBILITY FOR LOSSES,
EXPENSES, INCONVENIENCES, SPECIAL, DIRECT, SECONDARY OR CONSEQUENTIAL
DAMAGES ARISING FROM OWNERSHIP OR USE OF THE PRODUCT.

Products that are covered by the Limited Warranty will either be repaired or replaced at the option of

Inor. Customer pays freight to Inor, and Inor will pay the return freight by post or other “normal” way of
transport. If any other type of return freight is requested, customer pays the whole return cost.

MESO-HX must be powered from an certied isolating power supply or

zener barrier, placed outside the hazardous area. MESO-HX shall be
mounted in an Ex-compatible housing having protection IP20 or better.

INPUTS

MESO-HX may only be
connected to transducers
complying with ”Simple
Apparatus” acc. to

EN 60079-11:2007 § 5.7

Fig 9.

MESO-HX must be installed in an enclosure having

!

an Ingress Protection suitable for the actual use
but at least IP20.
If MESO-HX is mounted in a housing (head) made of light metals and
installed in hazardous area make sure the content of magnesium (Mg)
in the light metal is less than 6%.

If MESO-HX is mounted in a housing which is isolated from ground and
can be charged to an ignition capable level, then the housing shall be

electrostatically grounded when installed in hazardous area.

CABLE LENGTH

To cal cu late maximum
length of the cable for
reliable communication,
add load resistance and
approximated cable re­sistance. Please note that
the loop resistance for
relia ble commun ication
must be in the range 230

– 1100 Ohm, 250 Ohm is

a commonly used value.

In the data-sheet for the cable you get the cable capacitance/meter. Use the

R value you calculated and the cable capacitance/meter together with the

diagram above to get the maximum length of the cable. For multidrop mode,

use the formula below.
The cable length can also be calculated according to the formula:

L = 65*106 / (R * C) – (Cn*5000 +10 000) / C
Where:
L: is the cable length (m)
R: is load resistance (including resistance of barrier)+cable resistance (ohm)
C: is cable capacitance/m (pF/m)
Cn: is the number of Meso transmitters in the loop.

L can also be changed to ft, if so C is given in pF/ft.

For Ex-version MESO-HX also the restrictions on cable capacitance Ci

and inductance Li stated in the Certicates and Approval documents

must be observed. Also national and regional standards and regulations
must be consulted.
