PTL578G wireless pressure transmitter

Wireless pressure sensors are low-power intelligent instruments that integrate pressure measurement, transmission, and reporting based on 4G communication networks. Adopting low-power wireless communication mode, no wiring is required, making installation faster, safer, and more convenient. The standard pressure measurement signal is transmitted through Ethernet and can be easily connected to the measurement and control system, with a wide range of applications. Can directly send data to a designated IP server. Supports both private and public servers. Support OPC data reading. Suitable for pressure monitoring in the production, storage, and transportation processes of oil and water wells, remote sensing of water conservancy and hydropower, pressure detection of gas pipelines, and liquid level detection of rivers, lakes, and seas.

Widely used in industrial production and equipment monitoring, energy and industrial applications, transportation and logistics, medical and laboratory fields.

After-sales

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.
