| 7 | 20.68 KPa | 2068 KPa | -690~609 KPa |
| Output |
Analog output: two wire 4～20mADC Digital output: two wire 4～20mADC and variable digital signal in accordance with HART AGREEMENT. |
| Power | supply voltage 12.5～45VDC |
| Limit load | Max load resistor Rmax in loop decided by the supply voltage,see the below drawing. HART AGREEMENT require the load resistor not less than 250Ω,not more than 600Ω |
| Communication distance | Max. 1.5Km, multi-address communication can connect 15 smart transmitters Max. |
| Output display | 4 digital display,5 digit LCD display, pointer type. |
| Marking | ExiaII CT5 ;explosion-proof isolation type |
| Zero offset | can positive offset or negative offset,but can not overstep the utmost value |
| Temperature |
environment temperature:-40～85℃ (When choose LCD : -20～70℃) Medium temperature: -40～104℃ |
|
Static pressure and one side overload |
3.45Kpa(Absolute) 31.2MPa(Gauge) |
| Relative humidity | 5～98%RH |
| Startup time | less than 5 sec |
| Capability change | less than 0.16cm3 |
| Damp adjust | 0.20～25sec. |
| Malfunction alarming | If appear malfunction, automatism diagnose function will output 3.9 or 21.0mA |
| Protection | To avoid the datas are modified random,can utilize software or protect switch lock the memory data. |
| Reference condition | zero is the lower limit and not offset, temperature 25℃, Atmospheric pressure, 24VDC power, silicon oil , diaphragm 316L, data adjust range the same as the up and lower limit of the range |
| Accuracy |
±0.1%, adjust range ≥0.1URL ±[0.05+(0.005URL/span)]%, adjust range 0.025URL~0.1URL ±[0.01+(0.006URL/span)]%, adjust range 0.01URL~ 0.025URL Note: accuracy have include the influence of linearity,hysteresis and repeatability |
| Stability | ±0.1%URL/year |
| Tem. influence | ±（0.05%URL+0.15%span）/20℃ |
| Static pressure influence | zero error 0.1URL/6.9Mpa |
| Libration effect | withstand frequency 200Hz at any direction, arouse error ±0.05%URL |
| Power influence | 0.005%/V |
| Load influence | no load influence |
| Install position influence | about 250Pa zero offset, can be eliminate via calibration,no range influence |
| RF interference | drift is ±0.1%span in the condition of 30-1000MHz frequency and the most field intensity 10V/m |
