Contacting Conductivity Sensors
Contacting sensors are ideal for most industrial water treatment applications. They work best if the process is non-corrosive, free of suspended solids, and has relatively low conductivity.
The 140 is a retractable high temperature conductivity sensor. It can be removed from the process piping without shutting down and draining the line.
The 141 is a screw-in type conductivity sensor. It is intended for use in liquids having moderate conductivity.
The 142 is a screw-in type of conductivity sensor. It is intended for use in liquids having low conductivity.
150 is most appropriately used as a set point detector in applications with a fairly broad control range. The sensor is a good choice for controlling blowdown in open recirculating cooling water.
The 400 is a screw-in type conductivity sensor available in three cell constants covering a broad range of conductivity. It has titanium electrodes and is available with both integral and quick-disconnect cable.
The 401 is a screw-in type graphite electrode sensor with a 10/cm cell constant. It is intended for clean, non-corrosive high conductivity samples or which a toroidal sensor may not be suitable.
The 402 is a retractable conductivity sensor available in four cell constants covering a broad range of conductivity. It is available with both integral and quick-disconnect cable.
404 sensors combine the conductivity sensor with a flow cell. The design has a small holdup volume, so response to sudden changes in process conductivity and temperature is rapid.
