This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
Apparatus APA592 is a pH/ORP/pION transmitter and ACA592 is a conductivity transmitter. They deliver a current in the range 4-20mA proportional to the level detected by sensor. The ambient temperature range is -20°C to +60°C. Transmitter is supplied by a DC voltage source 30V max. and has a maximum current draw of 23 mA.
Intrinsic safety parameters:
Ui = 30V ; Ii = 160mA ; Pi = 0.8W ; Ci = 5nF ; Li = 0.5mHUo = 11.8V ; Io = 5mA ; Po = 15mW ; Co = 1.45µF ; Lo = 1H
Ambient temperature range: from -20°C to +60°C.
The apparatus shall only be connected to an intrinsically safe certified equipment (see electrical parameters above). This combination must be compatible as regard the intrinsic safety rules.
