How it is selected & specified.
Non-contact capacitive level sensors are small point-level devices for compatible plastic or glass containers, not heavy process tank transmitters.
WELK confirms tank wall material, wall thickness, liquid type, mounting distance, output type and environmental protection before quoting.
Non-Contact Capacitive Level Sensor is presented as a configurable WELK product family. Final model limits, wetted materials, process connection, certificate and output signal are confirmed from the selected datasheet before quotation.
Point level switch selection starts from medium behavior, alarm point, mounting direction, density or dielectric, buildup risk, process connection, power and contact logic.
External capacitive switches are normally for compatible non-metal tank walls and simple point detection.
