SENSOREX
Frequently asked questions
Common questions about SENSOREX from 3G Electric.
What is the difference between the Sensorex S265CD and S265C pH electrodes?
The Sensorex S265CD and S265C differ primarily in junction type and cable length. The S265CD has a double junction, which helps prevent reference contamination in samples containing sulfides, proteins, or other fouling agents. The S265C has a single junction. Both have a round tip and Ryton PPS body, measure 0 to 14 pH, and use tinned leads. The S265CD comes with a 3.05 m cable, while the S265C is available with a 30.48 m cable. Selection depends on sample composition and installation distance.
What are the key specifications of the Sensorex CLD502 chlorine dioxide sensor?
The Sensorex CLD502 is an ion-selective electrode sensor for measuring chlorine dioxide (ClO2) in the range of 0 to 2 ppm. It features a PVC body and a 3.05 m cable with tinned leads. This sensor is suitable for applications such as water treatment and disinfection monitoring. It is designed for continuous or spot measurement of ClO2 concentration. The PVC construction offers chemical resistance to aqueous solutions. The tinned leads allow connection to compatible transmitters or controllers.
What is the purpose of the Sensorex PHAMP-1 pre-amplifier?
The Sensorex PHAMP-1 is a stainless steel pre-amplifier designed for use with any pH or ORP electrode. It has a BNC connection and a 5/8 inch overall diameter. The pre-amplifier conditions and transmits pH or ORP signals, allowing the electrode to be located farther from the analyzer without signal degradation. It is commonly used in laboratory water testing and industrial installations where the sensor must be placed at a distance from the measurement instrument. The stainless steel body provides durability in harsh environments.
What tip shapes are available in Sensorex pH electrodes?
Sensorex pH electrodes are available with several tip shapes, including round, flat, and bulb. Round tip electrodes, such as the S265CD and S267CD, are general-purpose and suitable for most aqueous samples. Flat tip electrodes, like the S6800/10/TL and S651CD, are designed for surface measurements or samples with low moisture content, such as semi-solids or flat surfaces. Bulb tip electrodes are also available for specific applications. The choice of tip shape depends on the sample type and measurement conditions.
What materials are used in Sensorex electrode bodies?
Sensorex electrode bodies are constructed from materials such as Ryton PPS, PVC, and stainless steel. Ryton PPS is used in models like the S265CD and S267CD, offering chemical resistance and high-temperature stability. PVC is used in sensors like the CLD502, suitable for aqueous solutions. Stainless steel is used in the PHAMP-1 pre-amplifier for durability. The material selection affects chemical compatibility and operating temperature range. Users should verify compatibility with their specific sample chemistry.
What connection types are available for Sensorex sensors?
Sensorex sensors are available with connection types including tinned leads (TL), BNC, and BNR. Tinned leads are used in models like the S265CD and CLD502, allowing direct wiring to terminal blocks. BNC connections are found on the PHAMP-1 pre-amplifier and some electrodes, providing a coaxial connection. BNR connections are used in models like the S651CD and S656CD. The connection type must match the input of the transmitter or controller. Cable lengths vary, with options such as 3.05 m and 30.48 m.
