The YC 3351 series intelligent pressure/differential pressure transmitter uses a globally leading central sensing unit. High-precision silicon pressure and differential pressure sensor technology and packaging process, single-crystal silicon pressure and differential pressure sensor Located at the very top of the metal body, away from the medium contact surface, it achieves mechanical and thermal isolation; glass The sintered sensor leads achieve high-strength electrical insulation with the metal substrate, improving electrical conductivity.The sub -circuit offers flexibility and transient voltage protection. Platinum-level accuracy reaches ±0.05%.
Unidirectional overpressure up to 25 MPa . Excellent static pressure performance, with static pressure error optimally controllable within... Within ±0.05%/10 MPa , the temperature effect is minimal, and the optimal controllability is ±0.04%/10K .
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 achieved remotely via a Hart handheld device or a computer with Hart software installed . This allows for the configuration of measurement information, the use of digital compensation technology, and the transmission signal via a built-in temperature sensor. The device compensates for this, improving measurement accuracy, reducing temperature drift, and exhibiting good long-term stability. Features include high reliability. The user-friendly external one-button reset function is designed to meet the needs of hazardous environments . Safety operating requirements. The quick menu facilitates operation and allows for complete parameter settings, providing comprehensive improvement.Improve the performance of the transmitter.

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 in pressure will cause a zero-point effect within a range of <0.4 kPa , which can be corrected by adjusting the zero adjustment; there is no range effect. |
