TTH300 with MID Certification

The temperature transmitter TTH300 is certified by an MID Parts
Certificate in accordance with the Measuring Instruments
Directive 2014/32/EU (MID) and the standard WELMEC 7.2. The
device with the appropriate configuration is therefore approved
for 'Custody Transfer'-measurements (fiscal metering).
The MID certification emphasizes the high accuracy, reliability
and durability of the TTH300.
Note
This chapter provides basic information on the MID-certified
transmitter TTH300. Before commissioning the device, full
information should be consulted in the supplied MID documents
(Parts Certificate and associated 'Description'). Any generally
applicable statements on the transmitter TTH300, especially
pertaining to explosion protection and device safety, remain
unaffected.

General

Devices with MID certification have their own EU declaration of
conformity. In addition to the declaration, the 'Parts Certificate'
and the associated 'Description' are enclosed with the device.
It is compulsory and imperative that the described areas of
application, requirements and restrictions are complied with for
the intended use of the device!
The requirements of explosion protection and functional safety
(SIL) remain unaffected by the MID certification.
The number of the partial certificate (TC11002) of the notified
body NMi Certin B.V. and the checksum (0x46c9) of the certified
SW revision 01.03.00 are printed on the name plate of the device.

Areas of application, conditions and requirements

The temperature transmitter TTH300 with MID certification for
custody transfer measurements is especially suited for
measurement and control systems in the oil and gas industry. In
addition to gas, any liquids except for water are permitted for
measurement.
The MID certification refers to a special configuration of the
transmitter. This must not be modified! An extract of the
conditions and requirements stated in the certificate follows
below:
• Communication protocol: HART 5, HART 7
• HW revision: 1.07
• SW revision: 01.03.00 with checksum 0x46c9
• The checksum of the software (firmware) is printed on
the name plate of the device
• On sensor Pt100 in a four-wire circuit
• Permissible measuring range:
−50 to 150 °C (−58 to 302 °F)
• Ambient temperature range without LCD indicator:
−40 to 85 °C (−40 to 185 °F)
Note
• Based on the MID certificate, an operation of the TTH300
with the connected LCD indicator is not permitted.
• The MID certification can generally be combined with all
certifications of explosion protection.
The ambient temperature and measuring range named in the
corresponding explosion protection certificate, however,
limit the ranges permitted in the MID certificate.

Installation and Operation

The following should be observed in particular during
installation and operation of the device:
• Protection against overwrite:
Local write protection (DIP switch 1) should be activated
after installation and configuration.
• The housing which encloses the transmitter must be
closed and secured against opening using a seal.
If the transmitter is integrated in the connection head of
a temperature sensor, – e.g. a SensyTemp TSP100
(TSP1x1) or TSP300 (TSP3x1) from ABB – the seal should
be applied over the gap between the top and the base of
the head.
