3151DP Transmitter

3151DP Differential Pressure Transmitter

Brief Description

3151DP 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.
