Product Details
TK-3051DP series differential pressure transmitter is used to measure the liquid level, density, pressure, and flow rate of liquids, gases, or vapors, and then convert them into 4-20mADC HART current signal output. It can also communicate with HART375 or HART475 handheld controllers for parameter setting, process monitoring, etc.

Range limit
Within the upper and lower limits of the measuring range, it can be adjusted arbitrarily
Suggest selecting range codes with the lowest possible range ratio to optimize performance characteristics.
Zero point setting
The zero point and range can be adjusted to any value within the measurement range in the table, as long as the calibration range is ≥ the minimum range
Installation location impact
Changes in the installation position parallel to the membrane surface will not cause zero drift effects. If the installation position changes by more than 90 degrees from the membrane surface, there will be zero position effects within the range of<0.4KPa, which can be corrected by adjusting the zero position. No range influence.
output
2-wire system, 4-20mADC, optional HART output digital communication, optional linear or square root output.
Output signal limit: Imin=3.8mA, Imax=20.8mA
alarm current
Low alarm mode (minimum): 3.8 mA
High alarm mode (maximum): 20.8 mA
Non reporting mode (hold): Maintain the effective current value before the fault
Alarm current standard setting: high alarm mode
response time
The damping constant of the amplifier component is 0.1s; the time constant of the sensor is 0.1-1.6s, depending on the range and range ratio. The additional adjustable time constant is 0.1 to 60 seconds.
The impact on nonlinear outputs (such as square root function) depends on the function and can be calculated accordingly.
Preheating time:< 15s
ambient temperature
-40～85℃
-20~70 ℃ with LCD display and fluororubber sealing ring
Storage temperature/transportation temperature
-50～85℃； When equipped with LCD display: -40~85 ℃
work pressure
The rated working pressure is divided into three levels: 16MPa, 25MPa, and 40MPa
Static pressure limit
From an absolute pressure of 3.5KPa to the rated pressure, the protective pressure can be greater than 1.5 times the rated pressure and applied to both sides of the transmitter.
Unidirectional overload limit:Unidirectional overload can reach rated pressure
