Performance index
The overal performance is the composition error based on the reference accuracy, ambient temperature effects and range static-pressure effects.
               
Accuracy index
±0.2%FS range (conventional)

Concrete performance index

(Zero-base range, reference conditions, silicone oil filling liquid, 316 stainless steel isolation diaphragm, 4~20mA analog output, the digital fine-tuning value is equal to the set point value of range.)

Accuracy
(The reference accuracy includes hysteresis, linear, setting ability and repeatability, which are based on terminal.) 
     ±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 amplifier unit and diaphragm capsule. The damping time constant of amplifier unit is adjustable within the range of 0~100s.
Diaphragm capsule (silicone oil)      
Time constant (s) (The time constant can be set according to the actual situation of field and is recommended 1S)    

Influence of installation position
The changing of installation position, which is parallel to the surface of diaphragm, will not cause the effect of null shift. If the change between the installation position and the surface of diaphragm do not exceed 90°, the null shift within 0.4KPa can be corrected by zero setting without influencing the range.

Influence of power supply
Less than ±0.005% range/v

Functional parameter
The limit value of range and sensor

Zero point and range adjustment requirements
  ·The zero point and range can be adjusted arbitrarily within the range limit value indicated in Table 1.
·The range should be larger than or equal to the min. range indicated in Table 1.

Applications 
Measurement of liquid, gas and steam

Output
Two-wire 4-20mA, linear output or square root output is selectable for users. Digital process variable overlays on

the 4-20mA signal, which can be applied to the host machines according with HART protocol.

Power supply
Need external power supply. While standard transmitter (4-20mA) has no load, work at 14.5-45V DC.
Loop load limit
The max. loop resistance is decided by the voltage of external power supply, the relations are as follows:

Note: The supply voltage range of transmitter with backlight display is 14.5~45V
     The supply voltage range of intrinsic-safety series transmitter is 14.5～28V.
    The working voltage while HART communication should be larger than 17.5V.

Limit of static pressure and max. overpressure

For  363D type, the limit value is from 0psia to flange rated
value or the smaller one in the rated pressure values of sensor.

Fault mode
Output code
While discovering the faults of sensor or microprocessor by self diagnosis, the transmitter will output one high or

low alarm signal to prompt the users. The alarm output value is subject to the factory configuration mode of transmitter:
    Linear output: 3.8＜I＜20.8
C4: I=20.8mA  high fault
CN: I=3.8mA  low fault
Temperature limit
Environment
-20℃～＋70℃ (Ordinary)
-40℃～＋85℃ (The highest)
Storage

Process
Less than or equal to atmosphere, see the following table:
