WP311 Series 4-20ma Underwater Submersible Water Level Pressure Transmitter

Short Description:

WP311 Series Underwater Submersible Water Level Pressure Transmitters(also called Static Level Transmitter) are immersion type level transmitters that determine liquid level by the measurement of hydrostatic pressure of liquid at the bottom of the container and output 4-20mA  standard analog signal. The products adopt advanced imported sensitive component with anti-corrosive diaphragm and applicable for level measurement of still liquids such as water, oil, fuel and other chemicals. The sensor chip is put inside a stainless steel or PTFE shell. The iron cap at the top protects the transimitter making the medium touch diaphragm smoothly. A special vented cable is applied to make the back pressure chamber of diaphragm connect well with atmosphere so that the level measurement value is not affcected by external atmosphere pressure change. The excellent Accuracy, Stability, Tightness and Corrosion proof of this series of level transmitter meet the Marine Standard. The instrument can be directly thrown into the target medium for long-term measurement.
