PTL802 micro differential pressure transmitter

The micro differential pressure sensor is assembled with an OEM silicon piezoresistive differential pressure oil filled core body. Adopting a high-temperature isolation device, the temperature can reach 300 ℃, and the shell is made of all stainless steel structure with strong corrosion resistance. The two pressure interfaces are M20 × 1.5 threaded connections, which can be directly installed on the measurement pipeline or connected through a pressure pipe. Applied to differential pressure, liquid level, flow measurement and control in aviation, aerospace, automotive, medical equipment and other fields.

    1. LONGLV provides customers with installation and debugging services, as well as other technical consultations. If necessary, technical personnel can provide on-site technical training. If the customer has any technical questions, the technical personnel will provide a response within 4 hours.
    2. LONGLV products are strictly designed and produced in accordance with the ISO9001 international quality system, with a 1-year warranty for sensor products and a 3-year warranty for instrument products, with a 7-day return and exchange policy and lifelong maintenance.
    (Human damage is not covered by the warranty, and customized products without quality issues are not returned or replaced.)
    3. For returns and exchanges caused by quality issues, Longlv will bear the return and exchange shipping costs. The cost of returns andexchanges for non quality issues will be borne by the customer.
    Note: Quality issues refer to customized parameters such as function, size, specifications, and installation method that are not customized according to customer requirements, do not meet functional requirements, have dimensional errors, and have inaccurate accuracy (excluding within the error range).
    Customized products require confirmation of drawings by both parties before processing and production. If the product does not meet customer requirements, a written objection must be raised within two weeks. If the customer does not raise an objection within the specified time limit, it will be deemed as qualified acceptance.
    If an objection is raised within the deadline and it is confirmed by both parties that it is a product quality issue or production has not been carried out according to the requirements confirmed by both parties, it can be exchanged or refunded. If there are no quality issues and the shipping model andthe contract signed model are complete and correct, no return or exchange service will be provided.
    4. The products returned for repair will have a test result issued within 3 working days and the repair will be completed within 7 working days.
