General technical performance and parameters
Output signal: 4-20mA.DC two-wire system (analog)
The two-wire 4-20mA DC signal is overlaid with a digital signal, and the user selects linear or square root output. (Intelligent)
Power supply: 12-45V.DC (see load characteristic diagram for details)
Power supply impact:<0.005%/V
Load impact: When the power supply is stable, there is no load impact.
Measurement accuracy: ± 0.075% of the calibrated range , ±0.1%,±0.2%,±0.5%
(The standard precision is ± 0.5%. If you choose other precision, please indicate it when ordering and selecting.)
Migration feature: Maximum positive migration amount of 500%
Maximum negative transfer capacity 600%
pourThe absolute value of negative migration is not greater than one engineering atmospheric pressure.
② The absolute value of the upper or lower limit after migration should not exceed the upper limit of the maximum measurement range.
③ The migration of differential pressure flow transmitters will damage the square root characteristic, so migration cannot be carried out.
④ Absolute pressure transmitters cannot perform negative transfer.
Damping: It is usually adjustable between 0.2 and 1.67 seconds, and the time constant increases when filled with inert fluid or with a remote transmission device.
Start time:<2 seconds, no preheating required
Working environment: ambient temperature -29~93 ℃ (analog amplifier)
-29~85 ℃ (digital/smart amplifier)
-29-65 ℃ (with display header)
Environmental humidity: 0-95%
Protection feature: IP65 protection capability
Explosion proof type: Explosion proof Exd II BT4-6
Intrinsically safe Exia II CT5
Static pressure influence: DP class zero position error: for 14MPa, ± 0.1% maximum range limit or ± 0.25% maximum range limit (range code 3), correction is given by zeroing under pipeline pressure.
HP class zero position error: ± 0.5% maximum range limit, calibrated by zero adjustment for 32MPa under pipeline pressure.
Electromagnetic radiation impact: 0.05% maximum range value, accepted radiation frequency of 27-500MHz, test field strength of 3V/m.
Indicator (%): The ammeter scale is 44.5mm in length and has an accuracy of ± 2%
LCD digital display accuracy ± 0.2%
Flange size: DN50, DN80 (can also be customized according to customer requirements, please specify when ordering)
Vibration effect: ± 0.05%/g when vibrating at 200Hz in any direction.
Installation position: The diaphragm is not installed vertically, which may result in a zero point error of less than 0.24 kPa, but it can be eliminated by adjusting the zero point.
