Product details
Principle, structure
The pressure used to measure the medium can also be converted into changes in liquid level height. The use of fully sealed capacitive sensitive components ensures excellent stability and reliability for pressure or liquid level measurement. The product can be optionally configured with the HART communication protocol, which can communicate with the control system or handheld device for setting, monitoring, testing, and configuration.
