WP311A RS485 Output 4-wire Integral Immersion Liquid Level Transmitter

Short Description:

WP311A Integral Immersion Liquid Level Transmitter measures liquid level by metering hydraulic pressure using the sensor probe put into vessel bottom. The probe enclosure protects the sensor chip, and the cap makes measured medium contact the diaphragm smoothly.

Description

WP311A adopts compact structural design and has no terminal box. Cable length is longer than measuring range ensuring redundancy. The probe is fully immersed in medium and supply is 24VDC cable lead. Customizable signal output can be regular 4~20mA or Intelligent Communications such as HART protocol and Modbus 4-wire RS485 interface.

The level transmitter has precise measurement, good long-term stability, excellent sealing and anti-corrosion performance. It can be directly put into water, oil and other liquids for long-term application. Special internal construct technology solves condensation and dew-fall issues. Probe can be particularly designed for lightning protection.
