High accuracy intellgent industry pressure transmitter
Overview
Smart pressure/differential pressure transmitter, in the circuit design, the modular design with microprocessor as the core and advanced digital isolation technology is adopted and it makes the instrument have high anti-interference and stability. At the same time, the transmitter is compensated by the built-in temperature sensor, which improves the measurement accuracy and reduces the temperature drift. It has the characteristics of good long-term stability, high reliability, and strong self-diagnosis ability.In terms of structure, the user can easily calibrate, set and configure the transmitter through the HART communication handheld operator.
Widely used in petroleum, chemical industry, electric power, metallurgy, water affairs, brewing and other industrial fields. For a long time, with the excellent quality of products and high-quality after-sales service, it has won unanimous praise from users.
Pressure/ DP Transmitter Characters
- high precision grade German high-precision single crystal silicon sensor chip,Accuracy≤±0.05%.
- Strong load resistance Double overload protection diaphragm design, single overpressure up to 25MPa.
- Excellent environmental adaptability Intelligent static pressure compensation and temperature compensation,Eliminates the influence of temperature, static pressure and overload on the transmitter,and control the comprehensive measurement error on site to the minimum.
- excellent long-term stability.Stability can be maintained at 0.1FS%/10 years.
- The latest one-key reset function does not affect the electrical protection level, which is safer and faster.
- Flexible remote assistance debugging function Realize remote and local parameter setting function configuration through Hart or RS485 communication and panel keys.
Function parameter
| Range limit |
| |
Within the upper and lower limits of the range, it can be set arbitrarily,Just make calibrate the range≥set range, It is recommended to select a range with the lowest possible turndown ratio to optimize performance. |
| Installation position influence |
| |
Changes in the installation position perpendicular to the diaphragm surface will not cause zero drift,If the installation position and the diaphragm surface change more than 90°,Null effects in the range < 0.4kPa will occur,It can be corrected by zero adjustment, no span influence. |

| Response time |
| The damping constant of the amplifier part is 0.1S,The sensor time constant is:(0.1~1.6)S,depends on turndown and turndown ratio.The additional adjustable time constant is:(0.1~60)S. The effect on non-linear output (such as a square root function) depends on the function,and can be calculated accordingly. |
