Absolute pressure transmitter

Absolute pressure transmitter

purpose

The delta chamber of CS-3051AP absolute pressure transmitter (see figure below) receives the measured absolute pressure signal on one side and is enclosed as a high vacuum reference chamber on the other side, which is then converted into a 4-20mA.DC signal output. It can measure the absolute pressure of degassing systems, distillation towers, evaporators, crystallizers, etc.

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)
Load characteristics:

Power supply impact:<0.005% output range/V
Load impact: When the power supply is stable, there is no load impact.
Measurement accuracy: ± 0.1%, ± 0.2% of the calibration range (standard accuracy is ± 0.2%, if other accuracies are selected, please indicate them when ordering and selecting.)
Range ratio: 1:100 or 1:10
Damping: usually adjustable between 0.1 and 16 seconds.
Start time:<2 seconds, no preheating required
Working environment: ambient temperature -29~93 ℃ (analog amplifier)
-29~75 ℃ (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: Zero position error: ± 0.5% maximum range limit, calibrated by zeroing 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 (%): LCD digital display accuracy ± 0.2%
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 0.24KPa, but it can be corrected by adjusting the zero point.
Weight: 3.9Kg (excluding accessories)
