Toroidal Conductivity Sensors
For flow-through installations where the samples are viscous, fibrous, or corrosive, Models 222 and 242 are ideal. Typical applications are found in the pulp and paper, chemical, and metals and mining industries.

The Model 222 is constructed of Teflon-lined carbon steel pipe for use in high pressure or high temperature lines. The Model 222 is available in one and two-inch pipe sizes. The temperature sensor mounts in an integral thermowell.

The Model 242 sensor is available in over 250 different combinations to meet the needs of many applications and installations. Line sizes range from one to four inches (25 to 100 mm). You can also select from several materials for contact rings, liners and o-rings. The Model 242 includes an integral temperature sensor.

The Model 245 Sanitary Flow- Through Toroidal Conductivity Sensor is available in 0.5, 1.0, 1.5, and 2 inch TriClamp® sizes. Wetted materials are FDA CFR Title 21, Parts 170 to 199 compliant. The sensor clamps into the process piping between TriClamp flanges. Special grounding rings are not needed because contact rings are built in. A separate temperature sensor can be ordered as an accessory.

All these features make the Model 245 sensor ideal for applications in pharmaceutical, biotech and food & beverage industries.

The Model 225 Clean-In-Place (CIP) Sensor is designed for applications in the pharmaceutical and food and beverage industries where processing equipment is routinely cleaned with 2% caustic at temperatures up to 100°C. Process installation is made with a customer supplied two-inch Tri-Clamp. The Tri-Clamp design in unfilled PEEK meets 3-A sanitary standards and is FDA compliant for repeated food contact applications.

The Model 226 Submersion/ Insertion Sensor, available in PEEK, incorporates a rugged, large bore, one-piece molded design. This sensor is ideal for applications with a high solids content.

The Model 228 Submersion/ Insertion Sensor is available in durable, chemically resistant PEEK and Tefzel®. The Model 228 has robust construction that stands up to high vibration conditions. A variety of mounting options are available. The Model 247 Toroidal Conductivity Sensor is ideal for cooling water, boiler blowdown, and metal plating applications. The Model 247 is constructed with a solvent-welded CPVC body. The sensor is easy to install.
