Micro Differential Pressure Transmitter
Micro Differential Pressure Transmitter
Brief Description

3151DR micro differential pressure transmitter adopts advanced-technology high-accurate compact smart sensor, to compensate temperature and static pressure with digital compensation technology which improves measuring accuracy and decreases temperature dr

Details

Technical Parameters 

Output signal: 4~20mAoutput with HART® protocol digital signal（two-wire system）

Power supply: Outside power24V DC, (power range 12V~45V)

Installation: Explosion-proof dⅡCT5, intrinsic safety iaⅡCT5

Drift features: Range upper and lower limit shall not exceed range limit after positive and negative drift. Maximum positive drift is 0.975URL, maximum negative drift is-URL at minimum range.

Temperature range: medium temperature -40～104℃, storage temperature -40～85℃, working temperature -40～85℃/-20～70℃ (with digital head)

Relative humidity: 0～100%

Damping: time constant within 0.2～32.0S is adjustable

Start time: 3S, no need to preheat

Performance: under standard test conditions like without drift, 316stainless steel isolation diaphragm etc.

Range ratio: 40:1

Static pressure and overpressure limit:

 input pressure of 0～13.8MPa (absolute pressure) to any side of transmitter, it will not be broken;

transmitter can work under static pressure between 3.45kPa (absolute pressure) ～13.8MPa（gauge pressure）

flange pressure: 68.9MPa
