0.075% Accuracy Flush Diaphragm Sanitary Pressure Transmitter with Tri-Clamp 50.5 for Food Industry

Product Description

QYB400-GH Sanitary Pressure Transmitter

QYB400-GH sanitary pressure transmitter adopts monocrystalline silicon sensor chip made of German advanced MEMS technology, combined with superb production process to achieve 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-GH pressure transmitter can be used to measure the level, density and pressure of liquid, gas or steam, and convert them into 4-20mA DC (superimposed HART communication) current signal output;
QYB400-GH series products can provide a variety of communication protocols such as HART/485-Modbus/FF.

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 in the direction 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. Flange products must be zeroed after installation before use.
