Product Details


The buoyancy force of the displacer is transferred via transmission lever and torque tube to operating rod of the sensor, where it acts on free end of sensor element.Four thin film metal strain gauge elements are sputtered onto sensor element, which change their resistance in the ratio of the tensile or pressure tension. These four thin film metal strain gauge elements are connected as a Wheatstone full bridge supplied from amplifier.

Vacorda High Temperature Steam Displacer Liquid Level Transmitter

The voltage at the diagonal bridge section which is proportional to the effective weight is fed to the electronic amplifier as an input signal. This voltage is converted via the electronic amplifier into the 4 to 20 mA or digital two-wire output signal. The amplifier is supplied by the signal current circuit in two wire mode.

 

HKD 3000 Series Intelligent Float Level Transmitter is a level transmitter developed by introducing foreign technology. It consists of an intelligent processing unit, a measurement room, an internal buoy and a torque tube assembly. Changes in the liquid level of the measured medium cause changes in the internal buoyancy. The changing force causes the resultant force of the torsion tube to change and is transmitted to the torsion tube assembly, so that the torsion tube and the mandrel are deflected synchronously. The detection device on the shaft detects the displacement of the deflection, and the intelligent processing unit converts the displacement into a 4-20 mA signal output. The intelligent processing unit can detect changes in the ambient temperature and linearly compensate the output signal. It can also compensate for changes in liquid density caused by process temperature changes.
HKD3000 series intelligent liquid level (boundary) liquid level transmitter provides standard 4 ~ 20mA current signal output, on-site LCD liquid crystal display, and can provide communication functions such as HART.
