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.
The field transmitter WHA-UT-F7B1-0-PP-Z1-Ex2 is an I.S. instrument that takes temperature measurement with a thermocouple or an RTD and sends the results wirelessly to a gateway. The device can read up to two sensors simultaneously. The sensor input ports are suitable for connection in Zone 0. The sensors are not part of the present certification; only input and output parameters of the connections are detailed. An additional port is provided for temporary communication with HART compliant IS hand held communicator when commissioning or/and checking the status of the device.
The device is powered with a single primary cell identified and tested according to IEC 60079-11. The cell is provided by Pepperl+Fuchs, product name W-BAT-B1-Li, and can be replaced also when device is in the hazardous area. The device contains an RF module and a PCB antenna for wireless communications.
A foil keypad is placed on the front side of the enclosure to give a visual interface when commissioning or/and checking the status of the device.
The equipments connected to the field transmitter WHA-UT-F7B1-0-PP-Z1-Ex2 must be compatible as regards to the intrinsic safety.
The equipment is intended to be used in an operating temperature range from -20°C to +60 °C.
For the risk from electrostatic discharge, the user will have to read the instructions.
