Description
Product introduction:
Model: 1151DP
Name: differential pressure transmitter
Manufacturer: Shanghai Automation Instrumentation Co., Ltd.
Application: 1151DP 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 drift. With long-term stable performance, reliable and strong self-diagnose capacity which makes it popular among transmitter market.
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
