Product Description

orifice plate differential pressure transmitter for flow measurement

 Product description

       High accuracy differential pressure transmitter is used for the level,density and pressure measure
ment of liquid, gas or vapor,then transfer into 4-20mA DC signal output.  High accuracy differential pre
ssure transducer is avaialbe to connect with HART communication to display,record,control,monitor data.

Features: 

1.real-time to revise meter configuration in meter process:ex.adjust range(span),monitored variable etc.
2.intelligent linear process pressure signal,insure reliability and accuracy of the measuring data on the
circuit 
   board there is reverse protect circuit , current foldback circuit,avoid circuit accidental damage.
3.parameter store in E²PROM after configuration,remain unchanged
4.high accuracy and reliability
5.solid-state element,plug type electronic circuit board,anti-vibration
6.anti-explosion structure,all-weather use
