Installation matters
(1) Choose a place that is easy to operate and maintain for installation;
(2) It should be installed as far as possible from the vibration source;
(3) It should be installed as far as possible from the heat source;
(4) Install directly on the pipeline or equipment, and clamp it to the six sides of the transmitter with the wrench.
(1) Care should be taken when handling and installing the transmitter to avoid collision and affect the performance of the circuit.
(2) There is an isolation diaphragm in the pressure inlet of the transmitter. Do not touch it with foreign objects.
(3) The external thread of the transmitter must pay attention to the seal, otherwise the pressure will not be unstable.
(4) The safety barrier shall obtain an explosion-proof certificate, and its installation shall be carried out in accordance with the requirements of its instructions.
(5) If you encounter problems during the installation and use of the product, please contact our company. If there is any abnormality in the product, please do not open it for repair. Please contact the manufacturer in time.
