Description
Z3051 series intelligent pressure / differential pressure transmitter is a fully isolated intelligent field measurement instrument with HART communication protocol optional, developed by our company.
The transmitter uses a fully isolated circuit technology design, and the sensor signals of the power supply box are isolated and processed, which greatly improves the stability and anti-interference ability of the whole equipment.
In addition to the three basic function buttons for adjusting the zero, range and zero pressure of previous smart transmitters, the transmitter is also designed to be used in combination with the three buttons M, S, and Z on the display. (You can set the measurement range without adding pressure, modify the zero and full pressure values), set display engineering units, linearity, square root conversion, set damping time, and fixed current output.
The transmitter also has parameter data backup and recovery functions. When data is damaged, it can be restored online with three keys, with which can immediately back up the modified data.
The key functions of the transmitter can be adjusted by communication software or Hand-hold device from our company.
It is widely used in industrial applications with extreme chemical and mechanical loads field and high electromagnetic radiation occasions.

Technical parameters
• The structure is simple and firm, no moving parts, long service life, small pressure loss, low operating cost.
• New structural design of mechanical vibration resistance, shock resistance and dirt resistance is adopted.
• It achieve high exchangeability and versatility from the detection probe to the transport discharge path.
• The circuit adopts surface mounting process, with compact structure and high reliability.
• Set the menu according to the general operation principle, and use Chinese characters to prompt, clear and intuitive, simple to operate.
• Within a certain range of Reynolds number, the output signal is not affected by the physical properties of the changes and components of the measured medium, and the instrument coefficient is only related to the shape and size of the vortex body, so it is generally not
necessary to reciliate the instrument coefficient after replacing the accessories.
• The 12864 full dot matrix LCD display with fine low power consumption displays the
instantaneous flow and cumulative flow, and compensates the measured temperature and pressure, and the data is rich and intuitive.
• It has the multipoint linear correction function and greatly improves the measurement
accuracy. After using the high-speed algorithm of single pulse and pulse by pulse
measurement, the compression or broadening calculation is only delayed one by one time, to achieve complete real-time linear compensation, this performance reaches the world’s leading level.
• The differential pressure compensation vortex street mass flowmeter can directly measure the mass flow rate, which is not affected by the medium component or the dry degree
change,and the measurement accuracy is higher.
• The temperature and pressure compensation built-in or external sensor automatically
corrects temperature and pressure, directly converting the working condition flow into mass flow or volume flow under standard state. The measurement is simple and accurate, and 12 compensation algorithms can meet almost meet all flow compensation requirements.
Application
For monitoring ventilation ducts, filters and fans in HVAC areas as well as for level measurement in closed pressurized tanks.
