Product Description:
SMP4630 series of intelligent input level transmitter is a new
generation of intelligent products which can accurately measure and
compensate the pressure and temperature characteristics of the
sensor by analysis and calculation of the digital signal, and
transmit the liquid level signal through the digital interface.
The product has been verified for a long period of time and the
data are running normally and reliably. It can resist the
electromagnetic interference signals of most occasions. The
products are designed and developed according to the requirements
of the national marine products, explosion-proof, GJB150, GB /
T2423, JJG860 and other standards or specifications. And also we do
the production and inspection according to the ISO 9001: 2015
quality management system requirements.
Features:
n SS 316L, IP68.
n Probe with anti-sedimentation, anti-sharp objects stabbed,
anti-marine biological growth.
n RS485 output
