PEC-500A Digital Conductivity Sensor

n  Measurement Principle

The conductivity sensor is a glass platinum electrode. In general, the voltage is in the form of a sine wave. Conductivity is determined by the ohmic formula based on voltage and current values.

n  Features

u  Power supply and output isolation design to ensure electrical safety.

u  Power supply and communication chip built-in protection circuit,strong anti-interference ability.

u  With a comprehensive protection circuit design, it can work reliably without additional isolation equipment.

u  The circuit part is designed inside the electrode, the environment is well tolerated, and the installation operation is easier.

u  RS-485 transmission interface, MODBUS-RTU communication protocol, two-way.

u  Communications, can receive remote commands.

u  Output more electrode diagnostic information, more intelligent.

u  Internal integrated memory, memory calibration and setting.

u  Information can be memorized after power off.

n  Applications

u  It is widely used in the monitoring of conductivity in water treatment, hydrological monitoring, wastewater treatment, swimming pools, fish ponds and fertilizers, chemicals, and biology.
