China China OEM China Firstrate FST800-211 adjustable flow pressure transmitter factory and manufacturers

China OEM China Firstrate FST800-211 adjustable flow pressure transmitter

DP1300-M gauge pressure/absolute pressure transmitter is used to measure liquid level, density and pressure of liquid, gas or steam, and then convert it into 4～20mADC HART current signal output. DP1300-M can also be used with RST375 handheld terminal or RSM100 Modems communicate with each other, through them for parameter setting, process monitoring, etc. The absolute pressure sensor is only installed on the high pressure side of the sensor diaphragm box as a reference value for static pressure measurement and compensation.

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
