DocumentDocumentNP400 RELATIVE PRESSURE TRANSMITTER INSTRUCTION MANUAL V1.0x G INTRODUCTION NP400 positive relative pressure transmitters are robust and reliable equipment suitable for general industrial applications. They are available in several measurement ranges and process connection modes. PRECAUTION Before operating the transmitter, carefully read its specifications and operating instructions. In case of damage caused by incorrect operation or inappropriate usage, warranty becomes null and void. The installation must be carried out by a specialized professional. The electronic instruments power supply must come from a proper instrumentation network. UNPACKING When unpacking, in addition to the transmitter itself, you should find: · A quick guide to installation and operation. · A sealed electrical connector. · A screw to fix the connector to the transmitter. IDENTIFICATION An identification label is attached to the equipment housing. On this label, you can find detailed information about the transmitter. Figure 1 shows the identification label: Figure 1 Transmitter identification SPECIFICATIONS Reference Conditions: Environment at 23 °C ± 3 °C, 24 V supply, 250 load.
