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 Smart Pressure Transmitter type APC-2000ALW is designed to measure gauge pressure, vacuum pressure and absolute pressure of gases, vapours and liquids. The Smart Differential Pressure Transmitter type APR-2000ALW/XX and APR-2200ALW/XX is designed to measure differential pressure across constrictions. The Smart Level Probe type APR-2000YALW/XX is designed to measure liquid levels in closed tanks. The transmitter consists of a housing, measuring head with process connection, measuring sensor and electronic module converting the signal from measuring sensor into unified amplified output signal. The transmitter housing is a flameproof enclosure made of aluminium alloy with a baked epoxy paint finish or steel (316). The housing consists of a main enclosure, two electrical threaded entries and two screwed access covers (one of which is equipped with a glass window). Inside the enclosure there is electronics with galvanically separated intrinsically safe sensor circuit with a level of protection ia mounted.
Rated ambient temperature range:-40°C < Ta ≤ 45°C (T6 and T85°C)-40°C < Ta ≤ 75°C (T5 and T100°C)
- When replacing parts within the enclosure use only those specified in the descriptive documentation
- Some of the permitted gaps in flameproof joints are smaller than the one specified inIEC 60079-1:2006 (ed. 6) and shall not exceed the values specified in the manufacturer's instructions.
