Product Details
GENERAL
The 3051 differential pressure transmitter is a popular device used in measuring pressure in industrial applications. It operates by measuring the difference between two pressure points and converting this value into an electrical signal that is subsequently transmitted for processing.
While there are many different types of differential pressure transmitters on the market, the 3051 model stands out for its versatility and accuracy. It is capable of measuring pressure differentials ranging from just a few inches of water to several thousand psi, making it a popular choice for many different types of industries.

In HART communication, the resistance in the power circuit is ≥250 ohms, and the power supply voltage is ≥15.5 volts
|
|
Communication distance
|
The diameter of the connecting wire is greater than 0.6mm, and the communication distance is about 1500
meters.
|
|
Display
|

|
|
Zero and span shift
|
The lower limit of the measurement range is not lower than the lower limit of the large measurement range,
and the upper limit does not exceed the upper limit of the maximum measurement range, that is, the working range does not exceed
the sensor the limit value, zero position and range can be set at any corresponding point of 4 ~ 20mA.
|
|
Zero pressure fine adjustment
|
use  keys or code potentiometer knob to correct the error caused by transmitter installation
position change or zero position drift, and adjust the pressure of transmitter to zero pressure value.
|
|
Damping value
|
electronic damping adjustable range 0-32 seconds.
