7. It has independent anti electromagnetic interference circuit and software anti interference design, which improves the reliability of the product.

8. There is an internal sensor for measuring temperature parameters, which improves the compensation performance of the transmitter's environmental temperature impact. Due to the direct contact between the sensor and the measured medium, temperature information of the medium in contact with the sensor can be obtained at the same time.

9. The on-site digital display meter configured for the transmitter can directly display the measured pressure value, output analog current value, the percentage ratio of the set range corresponding to the measured pressure, and the temperature value of the sensor body and its contact medium. This technology has been patented.

10. The transmitter has improved its fault recovery ability and greatly reduced the maintenance workload of the transmitter.

11. The LCD liquid crystal display meter operates in a multi parameter cyclic display mode.

12. Equipped with the remote communication function of the HART protocol, it not only achieves pressure measurement, but also adds temperature detection function between the sensor body and the contacted medium, providing users with more on-site working condition information, which is conducive to improving the effectiveness of process control.

13. Differential capacitive pressure sensor with all metal sealing δ The innovative design of the chamber structure has achieved significant improvements and good stability in differential pressure (pressure) and temperature measurement.

The 3151 series intelligent pressure transmitter, as a high-precision and intelligent on-site differential pressure parameter detection instrument, is used to measure the differential pressure, pressure, and liquid level parameters of various media in liquid, gas, and steam states, and convert the measured differential pressure parameters into 4-20mA standard electrical signal output. At the same time, it adopts the HART protocol and has the function of communicating with the manual operator or upper computer. The transmitter has the function of outputting parameter configuration, Can adapt to the needs of different users. It can accurately measure differential pressure, liquid level, vacuum degree, and specific gravity.

The transmitter has a dustproof structure, making installation, use, and calibration convenient and simple. The wiring terminals and electronic circuit board are placed in a sealed electrical compartment above the transmitter and are separated from each other. So during on-site wiring, the amplifier is still working in a sealed state. The transmitter has reverse polarity protection measures to prevent damage to the transmitter due to power connection. The volume change during operation is less than 0.16 milliliters, which can prevent excessive changes in the measured medium liquid column. Therefore, it is not necessary to add a condenser or liquid level cylinder to compensate for the volume change. The components of the transmitter in contact with the tested medium shall be made of 316L stainless steel material. The printed circuit board manufactured using surface mounted electronic components and plug-in design features fewer faults, convenient maintenance, strong universality, reduced spare parts, and reduced maintenance costs.
