Overview
The measurement of liquid level and pressure adopts HART fieldbus technology, which can provide more on-site information to improve the performance of the factory.
Product Details
performance index
The overall performance is based on the comprehensive error of reference accuracy, environmental temperature influence, and range static pressure influence.
Accuracy index
± 0.2% FS range (conventional)
Specific performance indicators
Zero based range, reference conditions, silicone oil filling, 316 stainless steel isolation diaphragm, 4-20mA analog output, digital fine adjustment value equal to the range set point value. )
accuracy
(Reference accuracy includes hysteresis, terminal based linearity, setting capability, and repeatability)
± 0.2% range
If the range is less than X
±[0.025+0.05

]%X value
Damping time constant
The total damping time constant is equal to the sum of the damping time constants of the amplifier component and the diaphragm box. The damping time constant of the amplifier component can be adjusted within the range of 0-100 seconds.
Membrane box (silicone oil)
Time constant (seconds) (can be set according to the actual situation on site, recommended 1 second)
Installation location impact
The installation position change parallel to the membrane surface will not cause zero drift. If the installation position changes more than 90 degrees from the membrane surface, zero drift within the range of 0.4KPa can be corrected by zero adjustment without affecting the range.
Power supply impact
Less than ± 0.005% range/volt

Range and Sensor Limit Values
Table 1.363D Range and Sensor Limit Values
Zero point and range adjustment requirements
·The zero and range values can be set arbitrarily within the range limits indicated in Table 1.
·The range must be greater than or equal to the minimum range indicated in Table 1.
Application scenarios
Measurement occasions for liquids, gases, and vapors
output
Two line 4-20mA, users can choose linear or square root output. The digital process variable is superimposed on a 4-20mA signal and is suitable for any host using the HART protocol.
power supply
External power supply is required. The standard transmitter (4-20mA) operates at 14.5-45V DC when unloaded.
Circuit load limit
The maximum circuit resistance is determined by the external power supply voltage, and the relationship is as follows:
Note: The power supply voltage range for transmitters with backlit display screens is 14.5-45V
The power supply voltage range of intrinsic safety series transmitters is 14.5-28V
The working voltage during HART communication should be greater than 17.5V
Static pressure limit and maximum overpressure
For the 363D type, the limit value is 0psia to the flange rated value or sensor
The smaller of the rated pressure values.

Fault mode
output code
If a sensor or microprocessor malfunction is detected through self diagnosis, the transmitter will drive and output a high or low alarm signal to alert the user. The alarm output value depends on the factory configuration of the transmitter:
Linear output: 3.8<I<20.8
C4: I=20.8mA fault high
CN: I=3.8mA fault low
