DP1300-M Series Gauge or Absolute Pressure Transmitters
DP1300-M gauge pressure/absolute pressure transmitter has a wide range of applications, including petroleum, chemical, gas, electricity, military, water conservancy, food and etc.
1. Independent innovation and anti-overload structure make the transmitter more secure.
2. Unique dual sensor technology, accurate and stable measurement.
3. This kind of monosilicon type smart transmitter has excellent insulation performance between the core components and the shell, which ensures that the sensor output signal will not be disturbed on site.

| Span Limit | Within the upper and lower limits of the span, it can be adjusted arbitrarily; It is recommended to select a span 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 span 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 |
