WP311B Immersion Type 4-20mA Water Level Transmitter
WP311B Immersion type 4-20mA water level transmitter can be used to measure & control liquid level in：
★ Level measuring
★ Building automation
★ Ocean and marine
★ Constant pressure water supply
★ Metallurgy, environment protection
★ Medical treatment and etc.
WP311B Immersion type 4-20mA water level transmitter(also called hydrostatic pressure transmitter, Submersible pressure transmitters) use advanced imported anti-corrosion diaphragm sensitive components, the sensor chip was put inside of a stainless steel (or PTFE) enclosure. The function of the top steel cap is protecting transmitter, and the cap can make the measured liquids contact the diaphragm smoothly.
A special vented tube cable was used, and it makes the back pressure chamber of diaphragm connect well with atmosphere, the measurement liquid level is not affected by the change of outside atmospheric pressure. This Submersible level transmitter has accurate measurement, good long term stability, and has excellent sealing and anti-corrosion performance, it meets marine standard, and it can be directly put into water, oil and other liquids for a long-term use.
Special internal construct technology completely solves the problem of condensation and dewfall
Using special electronic design technology to basically solve the problem of lightning strike
