Double Flange DP transmitter

3851 Double flange differential pressure transmitter

Brief Description

3851 double flange 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.
