Operation manual of LMP633 series - 1

Submersible pressure transmitter quick installation manual Safety Precautions Wire rope supporting /! Pressure transmitter should be installed by professional engineers or qualified technical personnel, product specifications and important information provided on the label should be carefully read before installation and wiring operations. /! Pressure transmitter is powered by an external power supply, the power supply circuit should comply with energy-limiting circuit by relevant standards, and pay attention to the high voltage circuits there may exist. /! The maximum static pressure overload has been stated on the product label, the process maximum pressure should not exceed the full span of sensor. ! Using pressure transmitter in hazardous areas, installation, use and maintenance should also comply with the operation manual and relevant requirements of national standards. Clamps installation For products with more than 50 meters cable, the wire rope and cable bundled multi-point should be used to strengthen the level transmitter support. i Important information ^ Static pressure overload ^ Power supply ^ Signal outline type ^ Explosion proof mark ^ Intrinsic safety equipment parameters ^Certificat^^^^^^ /! Please note! Exceeding static pressure overload will cause damage to the instruments, even lead to burst and casualties. Clamps can be used to fix and support the entire product for direct cable connection level transmitter. Cable outlet should be of sufficient length, preferably directly connected to the control room, or use the adapter junction box for cable adapter, avoid bare connections in the field environment, leading into the liquid. Brackets installation-panel bracket Product usage Container level measurement Submersible level transmitter is mounted on the top of the vessel and is used to measure the height of the liquid in the vessel ! Must ensure that the tank connect to the atmosphere directly to avoid measurement error caused by static pressure inside the container and damage caused by overload pressure. Brackets can be used to fix and support the entire product with terminal box type level transmitter. Generally the installation location of the junction box at least 1.5 meters above the ground. When the installation is in the underground, manufacturers supporting cable should be used to connect to the control device, to avoid the condensation fluid in junction box in high humidity environment. Brackets installation-pipe bracket Protection sleeve Submersible Level Transmitter should be integrally mounted in the protective sleeve to avoid the impact on the level transmitter from fast flowing medium. Protection casing should be above the level surface, to avoid the influence on measurement accuracy from sur face disturbances. Level transmitter probe should be higher than the bottom at least 20cm, to avoid the blockage of impurities and sand. Brackets can be used to fix and support the entire product with terminal box type level transmitter. Generally the installation location of the junction box at least 1.5 meters above the ground. When the installation is in the underground, manufacturers supporting cable should be used to connect to the control device, to avoid the condensation fluid in junction box in high humidity environment. Flange connection Counterweight It is unable to install the protective tube in some fast flowing areas, so the counterweight can be used to fix the level transmitter. The counterweight can be used to fix the level transmitter for big density media also. ! Ensure that the container is connected with atmosphere to avoid measurement errors by the static pressure in the container or the damages by the overpressure. The flange is used to secure and support submersible level transmitter in the top of the container, when the installation is in the underground, manufacturers supporting cable should be used to connect to the control device, to avoid the condensation fluid in junction box in high humidity environment.
