Process and plant engineers looking for a simple, economical way to measure pH/ORP in pressurized tanks and main lines will find the precision S656CD Sensor Electrode installed with the S675 Hot-Tap Assembly from Sensorex simplifies installation and maintenance to reduce instrument installed and life-cycle costs.
The flat-surface, self-cleaning S656CD pH/ORP electrode combined with the rugged, cost-effective CPVC S675 Insertion Assembly enables pH measurements to be made in pressurized tanks and main lines without having to use expensive stainless steel components. It is ideal for use in a wide range of dirty applications for municipal and industrial water and wastewater treatment, offering superior accuracy, lower maintenance, longer life and alower operating cost.
The S656CD insertion pH/ORP electrode with the S675 Hot-Tap Assembly is typically installed in Acid Neutralization Systems. pH is monitored with these systems prior todischarge of water back into disposal or sewer lines to prevent wear and corrosion of the pipe line.
The S656CD insertion pH/ORP electrode features standard HT gels and reduced breakage potential, with four protective pads to reduce pHglass breakage. Its flat surface measuring glass design reduces coating andbuild-up in turbulent flows to extend electrode life and reduce technician maintenance activities.
The S656CD features a measurement range of 0-14 pH (0-12 pH without Na+ error), and the S656CD-ORP ±2000 mV for ORP. The electrode operates a minimum temperature of 50ºF (10ºC) and up to 185ºF (85ºC) depending on the maximum pressuredesired, which can be up to 80 psig.
The S675 Insertion Assembly uses a 1-inch full-port ball valve to allow installation or removal without system shutdown, saving time and money. The insertion assembly can be fully retracted through the ball valve, which is then closed, isolating the electrode and holder from the pressurized system. This is accomplished without draining the tank or de-pressurizing the line.
The user-friendly S675 Assembly features an easily-adjustable insertion depth, which allows the user to position the sensor in a turbulent area of the tank or line to optimize the flat surface electrode's self-cleaning feature. The special electrode used in the insertion assembly allows it to be mounted in any position, even through the bottom of a tank with its measuring surface facing upward. In abrasive applications, the electrode is usually positioned close to the pipe wall, an assembly well-suited for measurements in liquids with high suspended solids and for measurements in viscous liquids.
