Smart Differential Pressure Transmitter 4-20mA Output HART Protocol

Product Detail

Digital Pressure transmitter

Model: AT30511series
Name: Smart pressure transmitter
Brand: Yantai Auto Instrument
Application: 3051 series smart transmitter is a high accuracy intelligent type field pressure measuring instrument, can measure differential pressure, pressure and liquid level of various of media in liquid, gas and vapour, it can also measure th flow rate parameter of the liquid when matched with throtting devices, and transfer the measured pressure parameter into 4-20mA standard electric signal output.
Main technical parameters
Types of measuring parameter: Differential pressure, gauge pressure, absolute pressure are optional
Measuring range:
1. Differential pressure: 0-0.15KPa-7MPa(select proper sensor according to differential range)
2. Gauge pressure: 0-0.15KPa-42MPa(select proper sensor according to differential range)
3. Absolute pressure: 0-40KPa-7MPa(select proper sensor according to differential range)
Temperature of the media contact sensor: -40~85ºC
Display parameters:
1. Measuring pressure
2. Output analog current
3. Percentage of the setting range corresponding to tested pressure
4. Temperature of the sensor body and the contacted medium
