YL-816 digital pressure switch

YL-816 intelligent pressure switch is an intelligent pressure switch that integrates pressure measurement, display, and control. It has multiple intelligent functions, such as one key reset, switching between multiple pressure units, and setting the action return difference

The YL-816 intelligent pressure switch is easy to adjust and easy to install. Equipped with two sets of relays, each set of control points is normally open and normally closed with dual control points. It can meet the requirements of high and low point control for various gases and liquids. At the same time, it can achieve various operation functions such as zero clearing, calibration, changing display units, and setting backlash. This intelligent pressure switch is equipped with a high-precision instrument amplifier to amplify pressure signals, and a built-in temperature sensor for temperature compensation. It is a high-precision device for detecting pressure and liquid level signals and achieving pressure and liquid level monitoring.

The YL-816 intelligent pressure switch has stable performance and can be widely used in automated systems for measuring pressure, such as mechanical engineering and automation control systems.

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.
