FAQ:
Q: Are you manufacturer or trading company?
A: We are 13-year professional manufacturer of Pressure/ Level/ Temperature transmitters with 4~20mA, Hart, Profibus & FF protocols, pressure sensors with SPI, I2C, 4~20mA, 0.5~4.5V and etc, and electronic switches. We provide high quality products with high competitive factory price.
Q: What's your quality control system?
A: As an ISO9001:2015 certificated manufacturer, we have strict quality control system, and each product is done fatigue testing, calibration, temperature compensation before shipment. High quality is guaranteed.
Q: Is there MOQ with your product?
A: We have no MOQ limits, 1pc for testing purpose is acceptable.
Q: Can we print our logo on the products? Do you provide customized products?
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.
