Product Description
Pressure Transmitter
I. Application of the pressure transmmitter:
This product is suitable for petroleum, chemical industry, sewage treatment, constant pressure water supply, environmental protection, machinery, metallurgy, electric power, national defense project and other fields for surface pressure, absolute pressure measurement, can also measure negative pressure, and is suitable for various occasions all-weather environment and all kinds of liquid, gas, steam pressure measurement and control.
II.. Product features
(1)good stability, long-term stability of zero and full degree up to 0.2%FS/ year. Within the scope of compensation temperature - 30 ~ 70 ºC, the temperature drift less than 0.2% FS, throughout the allowed working temperature range is less than 0.5% FS.
(2)Can be used to measure the reaction with 316 stainless steel liquid, gas, steam.
(3)Solid structure, no moving parts, high reliability, long service life.
(4)From wind pressure to water and oil, high-precision measurement can be carried out regardless of the mass of the medium under test.
(5)Easy installation, simple structure, economical and durable.
III. Working principle
Using piezoresistive pressure sensor principle, manufactured by silicon micro mechanical processing technology, pressure sensitive chip USES the imported, the chip is encapsulated within the 316 l stainless steel shell, and filling and filling silicone oil, medium pressure on stainless steel isolation diaphragm, by silicone oil to the sensitive chip, so as to output a linearly with the pressure is directly proportional to the voltage signal of change, after transformation of amplifying circuit, current, voltage output.

FAQ
Q: If the flowmeter can be used to measure chemical solutions?
A: Generally they can. Meanwhile we have to confirm whether the solution is conductive or not, then we have to know the solution's composition
and concentration and according to this can we finally confirm the what lining and electrode materials are available.
Q: Which industries are the flowmeter used?
A: The flowmeter is commonly used in metallurgy, petrochemical, papermaking, textile, water supply and drainage, sewage treatment,
pharmaceutical, food, biological, fine chemical industry, etc.
Q: What about the quality assurance service?
A: Our guarantee period is 12 months, the product quality problem that appears in the quality assurance period, we give free maintenance or change.
Q: Are you trading company or manufacturer ?
A: We are factory and has manufactured various flowmeters over 14years.
Q: How about your delivery time?
A: Depends on the order quantity, generally it is 2~4 working days if the goods are in stock.
or it is 7-9 working days if the order quantity is with 50 sets to be produced for all processes.
Q: Could we visit your factory?
A: Certainly, we welcome all clients visit us at their convenience for further understanding each other.
Q: What is your terms of payment ?
A: Payment below US$1000, 100% in advance; Payment over US$1000 can be 30% deposit before production, and the balance settled before shippment.
