LDZ-4B,LDZ-4B(S) Electromagnetic flow converterDetailed product description：

The LDZ-4B and LDZ-4B (S) electromagnetic flow converters (hereinafter referred to as converters) can be used in conjunction with various specifications of electromagnetic flow sensors (hereinafter referred to as sensors) to measure the volumetric flow rate of conductive liquids and liquid-solid two-phase fluids. They can convert low level millivolt signals from the sensors into 0-10mADC or 4-20mA DC standard signals proportional to the flow rate for display, recording, adjustment control, and flow integration.

LDZ-4B/LDZ-4B (S) electromagnetic flow converter features:
Equipped with advanced excitation circuit to generate intermittent positive and negative alternating rectangular wave constant current for sensor excitation. The excitation frequency is one eighth of the frequency of the industrial power grid.
Zero point stability.
Has strong anti-interference ability.
Low power consumption.
The impact of electrode contamination is minimal.
The signal line connection distance between the converter and the sensor can be extended without the need for a dedicated dual core double-layer shielded cable.
The damping time constant is continuously adjustable.
Due to the small excitation current, the temperature rise and heat generation of the sensor are also small.
The LDZ-4B (S) converter can measure the volumetric flow rate in both directions and output status signals.
