Additional Information
Includes diagrams and tables illustrating structural components, connection types, and measurement ranges. Guidelines for selecting the appropriate cell constant and configuration based on application needs are provided.
Sensor Specifications
Details for intrinsically safe conductivity sensors with stainless steel cases, including screw (SA6-13) and flange (SA6-14) connections. The sensor cable is EC-10, 8 mm diameter, made of polyethylene and vinyl, with an insulation resistance of at least 105MΩ/100m. Maximum cable length is 50m, available in 5-meter units, weighing approximately 0.5kg per 5m.
Procedures
Installation guidelines for piping insertion-type and flow-through type installations. Recommendations include installing on top of horizontal pipes or horizontally on the side of vertical pipes, and using bypass and stop valves for flow-through installations.
Standards and Recommendations
Screw standards are Rc 1/2, and flange standards are 15A JIS 10K RF. Sensors should be installed away from harsh vibrations, corrosive gases, and chemicals. For cell constants of 1.0/cm and 10/cm, mounting at an offset of at least 45 degrees is recommended for air bubble removal.
Figures and Diagrams
Illustrations of installation methods emphasize proper orientation for accurate readings and maintenance ease.

SWBM-161-1

INTRINSICALLY SAFE CONDUCTIVITY TRANSMITTIER This product is a two-wire intrinsically safe explosion proof electro conductivity transmitter. It complies with Exia II CT4X explosion proofing standard and features an IP65-compliant protective construction. By selecting from four types of reference cell constants, a wide measurement range from ultrapure water to plant wastewater is supported. Sensor (screwed type) Features Modifiable transmission output range Within the designated measurement range, transmission output of DC 4-20mA can be freely set with a width of at least 25% or more of the maximum scale value of the measuring range. Adjustment of measurement values Measurement values can be adjusted to match electro conductivity values such as a secondary standard instrument. Simple operation with waterproof sheet-enclosed keys on front panel Operations such as mode switching can be performed using waterproof sheet-enclosed keys without having to open the door. Sensor supporting a wide range of applications The model SA6 Sensor comes in a screwed type and flange type, and is available as an immersion type with a length of up to 2m, or a flow liquid type (with case).
