Technical parameters of 3351 series intelligent pressure/differential pressure transmitter

Target audience: liquids, gases; And steam
Power supply voltage: 12-36V DC, standard value 24VDC;
Output signal: 4-20mADC; (Special for four wire 220V AC power supply 0-10mA DC output)
Environmental temperature: -25~70 ℃ (for general transmitters), -15~70 ℃ (with on-site indicators)
Storage temperature: -40-100 ℃;
Protection level: d Ⅱ BT4 ia Ⅱ CT5
Power supply impact: less than ± 0.005%/V of the output range;
Vibration effect: Vibration at 200Hz in any direction causes an error of 0.05%/g of the maximum range (micro differential pressure of 0.25%/g);
Installation position impact: When the working diaphragm is not installed vertically, a zero position error of no more than 0.24Pa may occur, which can be eliminated by adjusting the zero position and has no effect on the range;
Accuracy: Intelligent type; 0.075%
Stability: not exceeding the accuracy of the transmitter within six months
Indicator: The on-site output indicator has an ammeter with a linear indication of 0-100%; 3-1/2 digit LCD display range and zero position: externally continuously adjustable
Positive and negative migration: Differential pressure transmitter: maximum positive migration is 500%, maximum negative migration is 600%
