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.
Pressure Transmitter Model LHC-M51 and PPC-M51 and Pressure Sensor LHCS-51 and LHCR-51 are used in potentially explosive atmospheres caused by the presence of flammable gases, liquids, vapours or dusts for the measurement of level, flow, differential pressure, over- and under pressure.The pressure signal at the ceramic or metal sensor is converted into an electrical signal.The output of the Pressure Transmitter is a 4 - 20 mA current output signal with or without a superimposed HART digital signal, or the transmitter is intended to be connected to a fieldbus system (Profibus PA and Foundation Fieldbus).The several versions of the Pressure Transmitters differ in type of sensor, type of enclosure, process connection etc.Optionally all versions of the Pressure Transmitters may be provided with an indicator.Optionally the Pressure Transmitters that are intended for application in explosive gas atmospheres, may be provided with a sensor with extension cable.For electrical and thermal data, refer to the Annex of this certificate.
