Description:

The Model 228 is a submersion-insertion type toroidal sensor. Because it measures conductivity by inducing a current, the toroids do not need to touch the sample, but can be encased in plastic. Thus, unlike metal electrode sensors, the Model 228 sensor can be used in corrosive and dirty samples. It is also ideal for measuring high conductivity liquids.

The sensor is available in glass-filled PEEK and in filled and unfilled Tefzel®. The temperature limit is 248ºF (120ºC); although a high temperature (392ºF (200ºC)) PEEK version is available. The pressure limit for PEEK body sensors is 295 psig (2135 kPa abs) and for Tefzel body sensors is 200 psig (1480 kPa abs).

Mechanical and manual retraction assemblies that allows the sensor to be removed from the process piping without shutting down the process and draining the line is also available.

Specifications:

Wetted Materials: Glass-filled PEEK

Temperature: 32ºF - 248ºF (0ºC - 120ºC)

Pressure: 295 psig (2135 kPa abs)

Conductivity range:
analyzer 1056 and 56: 5 uS/cm min -- 500 mS/cm max
all others: 50 uS/cm min -- 1000 mS/cm max

Process connection:
-80: 1-inch MNPT
-81: 7/8-inch 9 UNC

Cable length: 20 ft (6.1 m)

Maximum cable length: 200 ft (61 m)

Installation: Install the sensor so that it is completely immersed in the process liquid.

Competitive Advantage:

CORROSION AND FOULING RESISTANCE with non-contacting toroidal sensors - great for use in dirty, corrosive, or high conductivity liquids for measuring concentrations of acid, base, and salt solutions.

SCREW-IN OR RETRACTABLE INSTALLATION OPTIONS allows the sensor to be removed from piping and tanks without shutting down and draining equipment.

RUGGED CONSTRUCTION tolerates high vibration applications such as drilling mud shaker trays. The metal frame and toroids are overmolded with either PEEK (glass-filled) or Tefzel (glass-filled or unfilled).
