V. APPENDIX MID
APC-2000ALW PRESSURE TRANSMITTERS,
GAUGE and ABSOLUTE,
APPLICATIONS ACCORDANCE IN EN 12405-1:2005+A2:2010 STANDARD
1. INTRODUCTION
1.1. The "MID Appendix" applies only to the APC-2000ALW absolute / relative transmitters applications where
they are as instruments for use in/as measuring devices (MI-002 gas) in accordance with the EN 12405-1:2005
+A2:2010 standard harmonized to Measuring Instruments Directive (MID) 2014/32, and the OIML R140:2007
recommendations.
1.2. The appendix contains the transmitters data to realizations them to uses in metrology. During the
installation and use of pressure transmitters in the MID version, is necessary to use the
DTR.APC.APR.ALW.03(ENG) together with MID Appendix - in situations of ambiguous interpretations of text
connected with installation and service of transmitters made according to MID version the final resolution is as
written in MID Appendix.
2. APC-2000ALW transmitters in MID version. Inscriptions
APC-2000ALW transmitters made for MID applications have a rating plates on which there are at least given
below information:
An APC-2000ALW transmitter for MID applications distinguishes from the other applications by information at
rating plate that is made in accordance with EN 12405-1:2005+A2:2010 and is written a Number of Parts
Certificate. In place of the XX in the transmitter type is given the type of connection to the pressure installation.
Units of pressure on the rating plate of bars and MPa are used interchangeably.
3. APC-2000ALW transmitters in MID version. Application
3.1. Pressure Transmitters Series APC-2000ALW, version in accordance with EN 12405-1:2005+A2:2010, are
provided for use in gas volume conversion devices of type 2, equipped with a backup electrical power source
(battery, UPS) for gaseous fuels first and second families according to EN 437.
3.2. Using transmitters in the danger zones.
All APC-2000ALW transmitters in version according to EN 12405-1:2005+A2:2010 are Intrinsically Safe (Exi) or
Flame-proof (Exd), and as such are made in accordance with the standards set out in Exi or Exd Annex.
Transmitters in the version in accordance to EN 12405-1:2005+A2:2010 can operate in hazardous areas in
accordance to the designation of explosin-proof construction. Specific parameters of the Exi or Exd application,
according to ATEX, with certificate numbers are given on the nameplate of the transmitter.
APC-2000ALW intrinisically safe pressure transmitters in MID version have the following input
parameters: Ci = 30nF, Li = 0.75mH, -25ºC ≤ Ta ≤ 55ºC. Other parameters are in accordance with
“Exi.ATEX Appendix”. APC-2000ALW flame-proof pressure transmitters in MID version have the
temperature range: -25ºC ≤ Ta ≤ 55ºC, other parameters are in accordance with “Exd.ATEX Appendix”.
During installation and use of pressure transmitters in the MID version to be followed these parameters
and other data contained in "Appendix Exi.ATEX" or "Appendix Exd.ATEX" to Manual.
