PTL516 diffused silicon pressure transmitter

The PTL516 diffused silicon pressure transmitter adopts precision machining of the core body and silicon diffusion injection technology for sensitive components, forming a Wheatstone full bridge. An anti-interference resistor is built inside the bridge. When the pressure acts on the core body, the resistance value is compared with the previous state to generate a MV signal proportional to the pressure, which is converted into a standard electrical signal through a secondary amplification circuit. The amplification circuit uses imported processing chips, high stability, high-precision silicon resistance full bridge, dedicated integrated circuit automatic calibration, strong temperature drift resistance, and the core body is made of 316 stainless steel material, corrosion-resistant and high-temperature resistant.

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.
