Overview: The Switch-Tek Non-Intrusive Capacitance Switch is designed for level detection in non-metallic tanks containing clean or ultrapure, aqueous-based liquids. It is suitable for media such as deionized water and hydrochloric acid, providing a reliable switch interface with remote devices like PLCs, SCADA, or alarms.
Specifications:- Tank Mounting: Non-intrusive, suitable for non-metallic tanks.
- Tank Wall Thickness: Less than 1 inch (25 mm).
- Accuracy and Repeatability: ±1 mm and ±0.5 mm in water, respectively.
- Dielectric and Conductive Range: Greater than 10 constants and 100 micromhos.
- Supply Voltage: 12-36 VDC with a maximum consumption of 25 mA.
- Contact Type and Rating: Single SPST relay, 60 VA, selectable NO/NC.
- Process Temperature: -40˚ to 176˚F (-40˚ to 80˚C).
- Enclosure Rating and Material: NEMA 4X (IP65), PSO material.
- Cable Specifications: 4-conductor, #22 AWG shielded, standard length 10' (3m), with options for 25' (7.6m) or 50' (15.2m).
- Compliance: General purpose, CE compliance with EN 61326 EMC and EN 61010-1 safety standards.
Features:- Non-intrusive level detection through plastic tank walls up to 1 inch thick.
- Mounting brackets available in common tank materials for adhesive or tack-weld installation.
Ordering Notes:- Select the bracket material that matches the tank wall material.
- Each sensor includes one user-specified bracket; additional brackets can be ordered separately.
- Special cable lengths can be ordered by specifying the length at the end of the part number.
- For installations without conduit, a Liquid Tight Connector is recommended to seal the sensor.
