The DW268 micro-differential pressure transmitter utilizes variable capacitance sensing technology. This MEMS sensor boasts high sensitivity and long-term stability, along with strong anti-interference and anti-vibration capabilities, making it highly suitable for use in harsh environments such as marine, aerospace, metallurgy, power, and chemical industries. It is installed in a wall-mounted manner. In addition to the standard two-wire 4~20mA signal (four-wire 4~20mA when powered by 220V AC), the DW268 also incorporates two relay signals, allowing for alarming and control of the pressure difference in the monitored environment
Product Overview
The DW268 micro-differential pressure transmitter utilizes patented variable capacitance sensing technology (utility model, patent number ZL201520624816.1). This sensor boasts high sensitivity, long-term stability, and strong resistance to interference and vibration, making it highly suitable for use in harsh environments such as marine, aerospace, metallurgy, power, and chemical industries. It is wall-mounted. In addition to the standard two-wire 4~20mA signal (four-wire 4~20mA when powered by 220V AC), the DW268 also incorporates two relay signals for alarming and controlling the pressure difference in the monitored environment. Its compact and lightweight design facilitates easy installation. It also features reverse polarity protection.
