DP1300-DP Series Differential Pressure Transmitter – Maxonic Detail:

DP1300-DP Series differential pressure transmitter has high measurement accuracy, strong overload capacity, good stability, easy installation, and is suitable for various types of pressure measurement applications. It is widely used in power, metallurgy, petrochemical and pharmaceutical industries.

1. The monosilicon type belongs to the latest generation of differential pressure sensor technology, and has excellent performance in measurement accuracy, turndown ratio, overvoltage capability, and stability.

2. Compared with differential pressure sensors of the same accuracy level, the yield rate of monosilicon type is much higher than that of other early technologies such as capacitive type. There is no need for precision screening in the production process, and mass production of high-precision products can be realized.

Span Limit

Within the upper and lower limits of the span, it can be adjusted arbitrarily;
It is recommended to select a range code with the lowest possible turndown ratio to optimize performance characteristics.

Zero Point Setting

Zero point and span can be adjusted to any value within the measurement range in the table (as long as: calibration span ≥ minimum span).

Installation Location Influence

The change of the installation position parallel to the diaphragm surface will not cause zero drift effect. If the change of the installation position and the diaphragm surface exceeds 90°, the zero position effect in the span of < 0.06 Psi will occur, which can be corrected by adjusting the zero adjustment, with no range effect.

Output

Two-wire, 4～20 m ADC, HART output digital communication can be selected, linear or square root output can also be selected.
Output signal limit: Imin= 3.9 m A, Imax= 20.5 m A

Alarm Current

Low report mode (Mini): 3.7 m A
High report mode (Max): 21 m A
Non-reporting mode (hold): keep the effective current value before the fault and report
Standard setting of alarm current: high mode

Response Time

The damping constant of the amplifier part is 0.1 s; the sensor time constant is 0.1 to 1.6 s, depending on the range and range ratio. Additional adjustable time constants are: 0.1 to 60 s. The effect on non-linear output, such as the square root function, depends on the function and can be calculated accordingly.

Preheat Time
