Description
The sensor has two electrodes and a cell constant of 0.02 cm-1 or 0.1 cm-1. The small constant suits very pure water of low conductivity, the larger one middle values. The electrode withstands 0–110 °C and 0–1 MPa, and steam sterilization at 135 °C (275 °F) lasts up to 30 minutes, which matters for food and pharmaceutical lines. A Pt1000 is built in for temperature compensation. Sample flow is not limited, but air bubbles in it are not acceptable since they distort the result. It connects to the process through an adapter, a welding socket or a welding clamp. Besides boiler water and hydroponics, the sensor measures pure water resistivity in the semiconductor, food, pharmaceutical and power industries.
How to choose
The main selection parameter is the cell constant. Water of very low conductivity takes 0.02 cm-1 and higher values 0.1 cm-1. Next consider the connection, whether an adapter, welding socket or clamp is needed, and the temperature, since sterilization reaches 135 °C. If bubbles are possible in the stream, the mounting spot is chosen so that they do not enter the flow section.

FAQ
What cell constants does the SC4AJ have?
0.02 cm-1 and 0.1 cm-1.
What temperature and pressure does the SC4AJ electrode handle?
Temperature 0–110 °C and pressure 0–1 MPa. Steam sterilization at 135 °C is accepted for up to 30 minutes.
Which temperature sensor is built into the SC4AJ?
A Pt1000.
How is the SC4AJ connected to the process?
By adapter mounting, a welding socket or a welding clamp.
Do bubbles in the sample affect the SC4AJ?
Yes, air bubbles distort the readings, so there should be none. Sample flow itself is not limited.
