Economical Pressure Transmitter Type QSY8201
Manufacturer:QSY
 
|
QSY8201 adopts imported ceramic piezoresistive sensor as measuring element. Pressure acts directly on the front surface of ceramic film to make it deformated. Then thick film resistance printed on the reverse of the ceramic film makes a Wheatstone bridge with it. Based on the peizoresistive effect, the bridge will generate voltage signal which is directly proportional to pressure and exciting voltage. QSY8201 can contact with most media directly and has great temperature stability and time stability
Application: pump, compressor, automatic control of building, energy source, constant-pressure water supply, testing and control of industrial process |

Flanged Liquid Level Transmitter Type QSY364
Manufacturer:QSY
|
QSY364 is the ramification of QSY133. Because of big aperture and flange connection, it is adequate for unsealed environment, especially for measuring ropy or muddy medium and strong corrosive liquid and medium containing rich particles. It insures easy cleaning and prevents jamming and the advantages of ceramic sensors, great corrosion resistance and economical price, has been developed more. |

Smart Capacitive Pressure Transmitter Type QSY3051
Manufacturer:QSY
|
Based on traditional capacitive transmitter, QSY Capacitive Smart Pressure Transmitter adopts micro-processing chip to realize more functions such as communication. Manual Operator 268, Manual Operator 275 and hosts using HART Protocol can achieve both-way communication (reading \ writing data and diagnosing fault) in control room or any place where transmitters are located or control circuits are made. EEPROM is introduced into the transmitter to avoid data loss in case of power failure, so it is acceptable for liquid level measurement and pressure measurement on site. |
