The YL-813DP digital differential pressure switch is a high-precision intelligent differential pressure switch designed specifically for measuring the pressure difference at both ends. It is equipped with a high-precision diffusion silicon pressure sensor, which can accurately display the pressure difference in real time and has the characteristics of high accuracy and good long-term stability. This digital differential pressure switch is equipped with a bright red LED digital tube display, which has multiple functions such as clearing, switching between three units, and dual relay output. It is easy to operate and easy to install. And it can be optionally equipped with 4-20mA current output. The design of the circuit emphasizes stability and fully considers the design situation of the automation site, with strong anti electromagnetic interference, anti surge protection, anti reverse connection protection and other measures. Adopting 304 stainless steel shell and joint, it has good seismic resistance and can measure non corrosive media such as gas, liquid, oil, etc. It is widely used for measuring gas and liquid pressure. Mainly used to measure the difference in pressure between two ends.

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.
