PMR311 Industrial Pressure Transmitter
from:admin time：2022-10-25
read：PMR311 industrial pressure transmitter is a standard and
most popular transmitter applied in air and liquid pressure measuring. A
high sensitivity silicon pressure chip is employed in the sensor. The
most important specification for industry application is long term
PMR311 pressure transmitter is designed for
industry
application with perfect long term
stability.
