PTL535 diaphragm type digital pressure switch

The PTL535 diaphragm digital pressure switch adopts an imported pressure core, which has high accuracy and good stability. Fine compensation for temperature drift and nonlinearity. IP65 and PVC integrated casting wire with strong adaptability can be used in various harsh environments. Membrane isolation structure can be used to measure viscous, crystalline, and micro corrosive media. LCD display, standard current signal output and switch signal output. Reverse protection, small size, light weight, easy installation, maintenance, and use.

Widely used in enterprises and units such as petroleum, chemical, sewage treatment, urban water supply, machinery, metallurgy, power, scientific research, etc., the membrane isolation process has a unique flat non pressure hole structure, and there is no phenomenon of viscous medium blocking the pressure hole. It is suitable for measuring and controlling the pressure of various thick liquid coatings, asphalt, mud, crude oil, and other small, medium, and large scale environments in all weather conditions.

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.
