Inductive (Torodial, Electrodeless) Conductivity Sensor ISC40

2016-05-27 14:31:34

Description:

There are two basic sensor styles used for measuring Conductivity: Contacting and Inductive (Toroidal, Electrodeless). With Inductive Conductivity (also called Toroidal or Electrodeless), the sensing elements (electrode coils) of an inductive sensor do not come in direct contact with the process. These two matched (identical) coils are encapsulated in PEEK (or Teflon) protecting them from the adverse effects of the process. There is only one cell factor (constant) for the ISC40 Inductive Sensor. It covers nearly the entire conductivity measurement range ~ 50-2,000,000 µS/cm. Only on the low end (below 50 µS) does the accuracy of the sensor suffer. The ISC40 Inductive sensor is virtually maintenance free.……

Description

Inductive (Torodial, Electrodeless) Conductivity Sensor ISC40

There are two basic sensor styles used for measuring Conductivity: Contacting and Inductive (Toroidal, Electrodeless).

With Inductive Conductivity (also called Toroidal or Electrodeless), the sensing elements (electrode coils) of an inductive sensor do not come in direct contact with the process. These two matched (identical) coils are encapsulated in PEEK (or Teflon) protecting them from the adverse effects of the process.

There is only one cell factor (constant) for the ISC40 Inductive Sensor. It covers nearly the entire conductivity measurement range ~ 50-2,000,000 µS/cm. Only on the low end (below 50 µS) does the accuracy of the sensor suffer.

The ISC40 Inductive sensor is virtually maintenance free.

The accuracy is 0.5% of reading plus 0.5 microS/cm for any conductivity value, whether measured in rinse water or in concentrated acids. The materials of construction ensure a long life under harsh industrial conditions.

The erosion/abrasion resistant PEEK (Poly Ether Ether Ketone), which also features excellent chemical resistance in all solutions except fluoric acid or oxidizing concentrated acids. The ultimate material in terms of chemical resistance is the PFA (Teflon) for applications in hydrofluoric acid and oxidizing concentrated acids (nitric, sulfuric, oleum).

The ISC40G and ISC40s are available in PEEK (sensor type GG) for general use. In applications where sample is aggressive to Peek we offer the sensor in Teflon (Sensor type TG).

The ISC40 sensor is provided with a rugged Stainless Steel mounting thread, nut and gasket combination for ultimate flexibility in installation using bulk head installation technique. There is also a wide range of holders and options available for reliable in-line or off-line installation with double O-ring seals for long service life of the sensor. Additional models are available for use in Ball-Valve Insertion applications and in Sanitary Flange installations.

Both sensors have a large bore for optimal resistance to fouling processes and when properly installed, the flow will keep the sensor clean preventing measuring errors.

  • Inductive Conductivity technique for elimination of fouling and polarization errors.

  • Wide bore sensors for long term stability.

  • Installation flexibility by wide range of holders and by the use of universal bulkhead construction.

  • Wide rangeability in terms of conductivity (1 μS/cm to 2 S/cm) and temperature (-20 to 130ºC).

  • All applications where severe electrode fouling prevents the use of contacting electrodes.

  • All ranges except the (ultra) pure water applications.

  • All slurry applications where conventional systems suffer from plugging or erosion.

ISC40FF/ISC40FS/ISC40FD Holders 

This program includes flow fittings and their subassemblies for in-line or direct mounting of conductivity sensors in piping systems. A wide choice of construction materials gives the user the best solution for any process considering chemical resistance, pressure and temperature specifications.

  • Wide choice of construction materials.

  • High degree of standardization to all cells.

  • Easy mounting, service and removal or replacement of sensors.

  • Electrolitically polished stainless steel designs for optimal corrosion resistance.

  • Available with flange adapters.

Model PR10 Retractable "Hot-Tap" Holder

On-line measurements often present extra challenges, especially when routine maintenance is required. The PR10 is ideally suitable for applications where the sensors must be removed without interrupting or shutting down the process. Without any special tools the PR10 can be retracted safely from the process at pressures up to 5 bar (72 psi). The PR10 is a universal retractable assembly that can be used for all liquid measurements. The PR10 is designed to accept any commercially available pH/ORP or dissolved oxygen sensor that has a PG13.5 connection while still being backwards compatible with old Yokogawa electrodes.

For ease of use optional flush ports are available. In the retracted position the sensor can be kept moist, cleaned or even calibrated. This can all be done without process interruption or disassembly of the armature.

  •  One model for pH/ORP, dissolved oxygen, conductivity and inductive conductivity sensors

  • All commercially available pH electrodes, such as PG13.5, SMART sensors, Vario Pin, YEF and DIN connectors can be installed in the PR10.

  • Integrated protection cage

  • A "scraper" is built-in to each assembly to effectively scrape or wipe off the
    process from the PR10's shaft as it is being retracted from the process.

  • A safe "through the valve" insertion and retraction design

  • Simplified installation by optional ball valves with flanged or tapered connections

  • Optional flush port accessories makes it easy to keep sensors moist (pH) and clean, and also provides access for calibration if desired.

Calibration Standard Solutions

Yokogawa supplies Hamilton conducctivity standars whose stability of ±1% is guaranteed over a life cycle of 1 to 3 years, depending on the value.
