Information

High static pressure intelligent differential pressure transmitter measuring range, differential pressure: 0-1.3 ~ 6890KPa. Static pressure: 25, 32MPa. Zero point and range, digital, intelligent: It can be adjusted with the local range and zero button, or with a HART communicator. Analog, linear: range and zero are continuously adjustable. For positive zero and negative migration, the lower limit of the range must be greater than or equal to -URL; for the positive zero migration, the upper range must be less than or equal to + URL. The verification range is greater than or equal to the zui small range. Output digital, intelligent: 4 ~ 20mA DC, user can choose linear or square root output, digital process variable is superimposed on 4 ~ 20mA DC signal, which can be used by host computer using HART protocol. Analog, linear: 4 ~ 20mA DC, linear with process pressure.

Vibration effect, in any axis, the vibration effect at 200Hz is ± 0.05% URL / g power supply effect is less than ± 0.005% output range / volt. Load effect: No load effect unless there is a change in the power supply voltage. Electromagnetic interference, from 20 to 1000MHz, when the field strength reaches 30V / M, the output drift is less than ± 0.1% of range. Influenced by installation position, the zero point drift is at most ± 0.25kPa. All zero drifts can be corrected; no effect on range.

稳定性 High static pressure intelligent differential pressure transmitter stability, digital and intelligent for 6 months, ± 0.1% URL. Analog, linear for 6 months, ± 0.2% URL. Ambient temperature effects. Digital and intelligent zero point error ± 0.2% URL / 56 ℃. Overall error: ± (0.2% URL + 0.18% calibration range) / 56 ° C analog, linear. Zero point error: ± 0.5% URL / 56 ℃. Overall error: ± (0.5% URL + 0.5% calibration range) / 56 ℃. Static pressure effect. The zero point is ± 0.2% URL under 31027kPa static pressure. The zero point error can be corrected online by zero adjustment. The range can be corrected to ± 0.25% output reading / 6895kPa, vibration effect, in any axis, the vibration effect at 200Hz is ± 0.05% URL / g, and the power supply effect is less than ± 0.005% output range / volt. Load effect, no load effect, unless the power supply voltage changes. Electromagnetic interference, from 20 to 1000MHz, when the field strength reaches 30V / M, the output drift is less than ± 0.1% of range.

The zero drift caused by the installation position is at most ± 0.25kPa. All zero drifts can be corrected; no effect on range.
