The overal performance is the composition error based on the reference accuracy,
Accuracy index
±0.2%FS range (conventional)
Stability
≤±0.3%FS/5 years
(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 0.4KPa
±[0.15+0.09×
]%
Influence of static pressure
0.3%FS/4MPa (only 6KPa range)
Influence of zero point
Can correct the zero position again or conduct pressure zero position transference
according to the field installation position etc.
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 1KPa 2S/6KPa 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
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:
Range L: Unidirectional overpressure 4MPa
Environment
-20℃～＋70℃ (ordinary)
-40℃～＋85℃ (the highest)
Storage
-46℃～110℃
With header: -40℃～85℃
Process
Larger than or equal to the atmosphere, please see the following table
