| Digital quantity | Two-wire 4~20mADC and overlay digital signal in line with the HART protocol |
| Power supply | 12.5~45V DC |
| Load limit | Loop Rmax maximum load resistance depends on the power supply voltage. HART communication require the load resistance no less than 250Ω, and no more than 600Ω |
| Communication distance | The maximum communication distance is 1.5Km, Multistation communication can take up max15 units smart pressure transmitter |
| Output display | Four digital display, five LCD display, pointer type |
| Explosion-proof form | Basic type:ExiaII CT5; Explosion-proof type. |
| Zero shift range | Zero point can be arbitrary positive transfer and negative transfer, but the upper and lower limit of measurement range and pressure range should not be set exceeded |
| Temperature Range | Environmental temperature: -40~85℃ (-20~70℃ when select LCD indicator) |
| Medium temperature | -40~104℃ |
| Static and Unidirectional pressure range | 3.45Kpa(absolute pressure) 31.2MPa(gauge pressure) |
| Relative humidity | 5~98%RH |
| Start time | Start in 5 second |
| Capacity changes | less than 0.16cm3 |
| Damping adjustment | 0.20~25 |
| Fault alarm | If there is a breakdown of sensor or circuit, automatic diagnosis function will automatically output 3.9 or 21.0 mA. |
| Configuration protection | In order to avoid the transmitter is randomly change the configuration data, can lock the stored data by software or protection switch |
| Performance indicators | |
| Reference conditions | Zero as the lower limit and no migration, the temperature is 25 ℃, the atmospheric pressure, 24 VDC power supply, silicone oil, isolation diaphragm 316 stainless steel, data setting range is the same as the upper and lower limit range |

| Accuracy | ±0.1%(The error is less than 0.1% of full scale) |
| Stability | ±0.1% URL/year |
| Temperature effect | ±0.05% (URL + 0.05% range) / 20 ℃ |
| Static Pressure effects | Zero Error: the URL / 0.1 to 6.9 MPa |
| Vibration impact | Can stand a vibration of 200Hz frequency in any axia, cause a error is ±0.05%URL |
| Power supply | The adjustable range is less than 0.005% / V |
| Load impact | No load effect |
| Installation position effect | About 250Pa zero migration, can be eliminate by calibration, no scale effect |
| Radio frequency interference | in the 30-1000 MHZ frequency and maximum field strength under the condition of 10 v/m, caused by drift is ±0.1% of adjustable range |
