AST50 & AST60 Conductivity Sensors
Brand: Rhino Sensors
Features
- Double 1” MNPT threaded body can be used for either immersion/submersion or inline installation
- Redundant O-ring seals used on all versions for high on-stream reliability and long sensor service lifetime
- Can be used with most any mating conductivity transmitter simply by specifying proper TC
- For general purpose applications up to about 200,000 microSiemens with outstanding chemical resistance for a wide variety of media. Open front-end geometry resists clogging and reduces maintenance. Ideal for remote installations.
- Wetted insulator materials of construction are CPVC for AST50 or TEFLON/KYNAR for AST60 with 316SS electrodes as standard. The option to select other metals as electrode materials such as titanium, Monel and Hastelloy C-276 provides an unequalled chemical resistance capability with only minimal increase in cost.
- Dual EPDM O-ring seals ensure sensor reliability (Viton & Kalrez Optional). Front seal absorbs the brunt of chemical attack, allowing the rear O-ring to operate in a protected environment, and insure continued sealing.
- Available in cell constants of K=0.1/cm, K=1.0/cm & K=2.0/cm cover the most common conductivity ranges
- Exact recommended conductivity range for each cell constant depends upon mating instrument. Typical area of use is 10 to 200,000 μS/cm. For use below 10μS/cm a cell constant of K=0.05/cm or lower is required
- K=0.1/cm cell constant can be used for ranges as low as 10-200 μS/cm or as high as 50-5,000 μS/cm
- K=1.0/cm cell constant can be used for range as high as 100-100,000 μS/cm
- K=2.0/cm cell constant can be used for range as high as 200-200,000 μS/cm
- Cable length is 10 feet standard but extended lengths as integral cable or else by means of quick-disconnect waterproof and corrosion-resistant snap connections are available for ease of removal for cleaning and/or recalibration.
- Waterproofing sealing option for completely submersible installation without the use of an immersion rod or standpipe. Ideal for corrosive environments where the seal on the back of the sensor may be degraded in the course of time.
- Available in polypropylene (PP) and CPVC with integral vinyl or NORPRENE sealing hoses factory installed.
