Level flange rated pressure
PN series : PN 2.5 ~ PN 160
Class series: Class 150 ~ Class 250 0
Unidirectional overload limit
overload limits on the high and low pressure sides are the rated pressure of the liquid level flange , and correctable zero-point drift may occur .
Product Dimensions
The YC 3351 series intelligent pressure/absolute pressure transmitter uses a globally leading central sensing unit . High-precision silicon pressure sensor technology and packaging process; single-crystal silicon pressure sensor located in metal body. At the very top, away from the medium contact surface, mechanical and thermal isolation are achieved; the glass is sintered into a single unit for transmission. The sensor leads achieve high-strength electrical insulation from the metal substrate, improving the flexibility of the electronic circuitry. Performance and transient voltage protection capability. Minimal temperature variation, optimally controllable within ± 0.04 %/ 10 K.
The circuit design employs a microprocessor-based core, supplemented by advanced digital isolation technology. Its modular design gives the instrument extremely high anti-interference capability and stability. It uses the HART protocol. Communication can be completed remotely via a Hart handheld device or a computer with Hart software installed, enabling measurement. Information configuration is implemented, digital compensation technology is employed, and the transmitter is monitored via a built-in temperature sensor. Linear compensation improves measurement accuracy, reduces temperature drift, and exhibits good long-term stability and reliability . Advanced features. The external one-button reset function is designed for maximum user-friendliness, ensuring safe operation in hazardous environments. Requirements: A quick-access menu facilitates operation and allows for complete parameter settings, comprehensively enhancing the transmitter's performance . performance.

Functional parameters
|
Range Limit |
Within the upper and lower limits of the measuring range, it can be adjusted arbitrarily. It is recommended to choose a range code with the lowest possible range ratio to optimize performance. |
|
Zero point setting |
The zero point and range can be adjusted to any value within the measurement range of the table, as long as: the calibrated range ≥ the minimum range. |
|
Installation location affects |
to the diaphragm surface will not cause zero drift. However, if the installation position is more than 90° to the diaphragm surface... Changes There will be a zero-point effect within the range of <0.4 kPa , which can be corrected by adjusting the zero adjustment. There is no range effect. |
|
Output |
Two- wire 4-20 mA , NAMIR compliant NE 43 specification, superimposed digital signals ( Hart protocol) Linear or square root output can be selected. |
|
