Operation principle

ZTD-G Smart Displacer Level (Interface) Transmitter consists of DLT9000 level transmitter, measuring chamber, measuring mechanism, displacer and torque tube, etc. The liquid level changing triggers the change of the buoyancy of displacer, then it will be transferred into the torque tube unit. This makes the torque tube and core axle rotate synchronously. At the same time, the magnetic steel parts that fixed at the core axle of the torque tube turn rotary displacement. The Hall-effect sensor senses the magnetic field change and converts the magnetic signals into current signals. DLT9000 level transmitter uses micro-controller and relatedelectronic circuit to measure process variable, supply current output, drive LCD and support HART communication. Micro-controller receives the electric signals that have been temperature-compensated and linearised. Meanwhile, compensates the liquid density change caused by the change of the process temperature, then supplies 4~20mA current output signals. LCD can indicate analog output, process variables, process temperature (if RTD is installed), degrees of the torque tube rotation and percent range of variable, etc.
