A: Yes, we can print your logo on our products; OEM, ODM&customization are welcomed.
Q: What is the warranty of your products? And after-sales service?
A: Our warranty time is 12 months after shipment, and our after-sales dpt will respond with your questions in 24hrs, remote instruction by PC network is always available.
Q: What is lead time of your product?
A: We are factory, our lead time is always within 7 working days for products without customization, but lead time for flange products is a little longer.
WA19 series are based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element.
It is designed for o-ring mounting for the applications where compatibility with corrosive media is required. Each sensor was strictly temperature compensated for both zero and span.
There are two options of excitation power -- constant current and voltage.
