Yokogawa pH Sensor DPA405-120/01
Yokogawa's pH and ORP analyzers are highly reliable. They feature advanced functions and are useful for a wide variety of applications including water quality management in a broad range of production processes and in medium-sized wastewater treatment plants, or as general pH and ORP control systems. Based on Yokogawa's track record and years of experience, a comprehensive range of products has been produced to provide solutions best suited to individual applications. In addition to the PH8EFP, PH8ERP, OR8EFG and OR8ERG standard Ryton pH and ORP sensors, specialty pH and ORP sensors are available for various applications.
Features
pH/ORP Sensors for Chemical Processes : DPA405, DPA485
• Extremely long life span for pH measurement in electrolytic processes • With the pressurized inner solution there is no need for a pressure holder. • The silver barrier incorporated in the reference electrode inhibits the generation of sulfide around the liquid junction.
• With the pressurized inner solution there is no need for a pressure holder.
Specifications
pH Sensors for Chemical Processes (DPA405) Measuring range: pH 0 to 14
Measuring temperature:
0 to 100 OC (See Table 1 when using holder)
Measuring pressure: Atmospheric pressure to 250kPa (Depending on the inner pressure of the sensor) Internal electrolyte: High-viscosity gel
Measuring pressure:
Atmospheric pressure to 250kPa (Depending on the inner pressure of the sensor)
Temperature compensation sensor: None (Manual temperature compensation on the converter or transmitter) (Use adapter with temperature sensor (SA405) for application where the tempera- ture varies) Applicable holder: Yokogawa pH Sensor DPA405-120/01 Flow-through holder (PH8HF), Submersion holder (PH8HS) (An optional adapter is needed, but not needed when using an adapter with temperature sensor SA405.) Ultrasonic cleaning is not available. Only jet cleaning is available when cleaning is necessary. Use O-ring covered by Teflon (K9148MR) when using a special holder for electrolytic processes Wetted part materials: Body: Glass O-ring: Silicon rubber or Daielperfrow rubber Adapter: Stainless steel (SUS316), polypropylene, rigid polyvinyl chloride, heat-resistant polyvinyl chloride or titanium CAUTION ON USE: This sensor cannot be used outdoors, even when using with a holder, this sensor cannot be used outdoors due to exposure to rain or due to condensation at a high humid place. This sensor cannot be used with a guide- pipe holder. The sensor must be installed in a vertical position. It can not be installed from below and in a horizontal position, either.
