Alarm jumper: For the self-diagnosis to the inaccuracy failure of the process variables (for example, the electronic module failure). Configure the process variables of high and low alarms.
Operation principle
DLC series smart displacer level (interface) transmitter consists of imported original DLC3000 series smart level controller and 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. DLC3000 series smart level controller measures process variables with a controller and relative electronic circuit, supplies current output to drive LCD and support HART communication. 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.
