Two-Electrode RS485 Industry Online Conductivity Sensor With Replaceable Measuring Head
The replaceable measuring head digital conductivity sensor DEC890 is a digital sensor for measuring the conductivity of liquids.
Replaceable measuring head means that this type of conductivity sensor is designed with a detachable measuring head part. When the measuring head part of the sensor is damaged or fails, only the measuring head needs to be replaced instead of buying a new sensor, which reduces maintenance costs. If the measuring head part of the sensor fails, the replaceable design can quickly replace the new measuring head, avoiding long-term downtime of the sensor. The flexibility and maintainability of the sensor are increased, and the convenience and economy of use are improved. This design makes the digital RS485 conductivity sensor an ideal choice for industrial automation and liquid monitoring applications.
The digital RS485 conductivity sensor is a conductivity sensor that
uses the RS485 communication protocol to transmit data. The RS485
communication protocol supports long-distance transmission and can
be directly connected to a digital display, computer or control
system to facilitate data collection and processing.
It has strong anti-interference ability, high precision, automatic
temperature compensation, wide measurement range and can adapt to
the change of conductivity of different liquids. It is suitable for
various liquid conductivity measurement scenarios and various
industrial control and monitoring applications.
