Digital conductivity sensor 8D08

for water4-20 mAwith temperature measurement

By transmitting a constant amplitude and fixed frequency AC signal to the ring probe, for the liquid with different conductivity, the probe secondary will induce the same frequency signal of the corresponding amplitude, and the corresponding voltage signal will be obtained after the subsequent circuit processing. At the same time, the voltage signal corresponding to the real time temperature is taken. The standard conductivity values are compensated to 25 degree by function calculation. The value is displayed by LCD and converted to 4 to 20mA signal output at the same time. The principle block diagram is shown in Figure 3.1. Fig. principle block diagram Fig.3.2 Structure block diagram Figure 3.2 shows，The left side of the diagram is the front view of the CNPS-8D08 digital conductivity sensor. The right side is the back view of the transmitter of the CNPS-8D08 digital conductivity sensor. Installation and use： Precautions for safety of explosion-proof： The product is equipped with earthing terminals, and users should reliably connect with them when they are using products.。 With respect to cable frame site site operation of the staff and not easily smashed touch, damage, erection of safe and reliable principle。 The installation and maintenance of the field must follow the warning words of “power failure and opening”. The outer diameter of the cable sheath is 8. The tightened nut should be tightened when the field is used, so that the inner diameter of the sealing ring is tightly clung to the outer diameter of the cable. The cable sheath of the seal ring should be replaced in time. There should be no harmful gas on the installation site for aluminum alloy.
