Product features 

● Reference accuracy Digital and intelligent: ±0.2% calibration range; 

● Stability: Digital and intelligent: 6 months, ±0.2%URL； 

●Ambient temperature limits:  -40 to 85℃; 

● Process temperature limit: -40°C to 104°C. 

● Storage temperature limit:  -51 to 85℃; 

● Ambient humidity: 0-100% relative humidity; 

● Effect of ambient temperature: ±0.2%URL/56℃; 

● Overall error: ±(0.2%URL+0.18% calibration range)/56℃; 

● Zero error: ±0.5%URL/56℃; 

● Overall error: ±(0.5%URL+0.5% calibration range) /56℃; 

● Influence of static pressure: The zero error is ±0.5%URL; 

● Influence of vibration: The vibration effect under 200Hz is ±0.5%URL/g; 

● Power supply effect: Less than ±0.005% output range/volt; 

● Mounting position influence: The zero drift is no more than ±0.25kPa; 

● Measuring range: Differential pressure: 0-0.125～1.5KPa, static pressure: 1, 4 and 6.9MPa; 

● Zero and measuring range: Adjustment with local range and zero button or remote adjustment with HART manual actuator; 

●Zero positive and negative transfer: At the moment of zero negative transfer, the lower limit of measuring range must be more than or equal to -URL. At the time of zero positive transfer, the upper limit of measuring range must be less than or equal to +URL. The calibration range is no less than the minimum measuring range; 

● Output: 4～20mA DC. The user can choose linear or square root output. The digital process variables are superimposed on 4 ~ 20mA DC signal and can be used for the upper computer with HART protocol used; 

● Static pressure and overpressure limits: No damage will be incurred by adding 0-6.9MPa pressure to any side of the transmitter. At the moment of working within the static pressure scope of 3.45kPa-6.9MPa, the performance and specification requirement is met, and the volume change is less than 0.16cm3.
