Product Description

4 20mA RS485 HART High Accuracy Best Price Gauge  Absolute Smart Petroleum Water Chemical Pressure Transmitter Sensor Transducer

Product Description

QYB400-GP/AP Intelligent Direct Mount Pressure Transmitter adopts monocrystalline silicon sensor chip made of advanced MEMS technology from Germany, which combined with the exquisite production process, realises the high accuracy and ultra-high stability of the product. Embedded with intelligent signal processing module, it realises the perfect combination of pressure and temperature compensation, providing reliable measurement accuracy and excellent long-term stability.

QYB400-GP/AP monocrystalline silicon intelligent direct-connected pressure/absolute pressure transmitter can be used to measure the level, density, pressure of liquid, gas or steam, and convert it into 4-20mA DC (superimposed HART communication) current signal output;

QYB400-GP/AP series products can provide HART/485-Modbus/FF and other communication protocols.

Power Impact
0.001%/10V(12~36)V DC, Negligible
Range Limit
Adjustable at will within the upper and lower limits of the range It is recommended to select a range code with the lowest possible range ratio to optimise the performance characteristics
Zero Setting
Zero and range can be adjusted to any value within the measurement range in the table, as long as: calibration range ≥ minimum range
Mounting position effect
Changes in mounting position parallel to the diaphragm surface will not affect the zero point. If the mounting position is not parallel to the diaphragm surface, it can be corrected by adjusting the zero point. No range influence.
