Using advanced \u003cstrong\u003ecapacitive sensing technology\u003c\/strong\u003e, this sensor eliminates the common failures of mechanical float switches and resistive probes, providing accurate readings without moving parts that can jam or corrode.\u003c\/p\u003e \u003cp\u003eDesigned for both plastic and metal tanks, the sensor is insensitive to soiling, deposits, and tank pressure variations. Unlike pressure-based systems, it remains accurate during pressure filling or when tanks are sealed, making it a superior choice for modern RV and marine plumbing.\u003c\/p\u003e \u003ch3\u003eAdvanced Capacitive Measurement: How It Works\u003c\/h3\u003e \u003cp\u003eThe sensor employs a fully electronic, non-contact capacitive measuring method. Two adjustable stainless steel rods form a capacitor that changes linearly with the water level. The integrated electronics convert this into a stable 0–2.2 V signal, compatible with Votronic displays and many third-party monitoring systems. This method ensures consistent performance in short-term and continuous operation, with no risk of false readings due to sloshing or foam.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eAdjustable for tank heights 15–50 cm\u003c\/strong\u003e – rods can be cut to exact tank depth for a custom fit\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFully potted IP 67 electronics\u003c\/strong\u003e – sealed against moisture, frost, and vibration, ideal for underfloor and exposed installations\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eNo moving parts\u003c\/strong\u003e – eliminates mechanical wear, sticking floats, and cleaning requirements\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePressure-independent measurement\u003c\/strong\u003e – unaffected by tank pressurisation or vacuum during filling and venting\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eWide 7–32 V DC operating range\u003c\/strong\u003e – compatible with 12 V and 24 V battery systems, with reverse polarity and overload protection\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eVersatile mounting\u003c\/strong\u003e – install from inside or outside the tank top; fresh water tanks also allow bottom installation\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eCorrosion-resistant materials\u003c\/strong\u003e – suitable for fresh, grey, and black water in plastic, aluminium, steel, and stainless steel tanks\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eInstallation Flexibility\u003c\/h3\u003e \u003cp\u003eThe sensor mounts through a 38 mm hole using the included PG 29 threaded flange and sealing rings. The 75 cm connection cable simplifies wiring to the display unit. For fresh water tanks, bottom installation is permitted, offering additional layout options in tight spaces. The robust construction withstands the harsh conditions of underfloor tanks, including road spray and temperature extremes.\u003c\/p\u003e \u003ch3\u003eWhy Choose Capacitive Over Mechanical Sensors?\u003c\/h3\u003e \u003cp\u003eTraditional float sensors are prone to sticking, especially in grey and black water tanks where debris and sludge accumulate. Resistive probes can suffer from electrolysis and false readings due to conductive deposits. The Votronic capacitive sensor avoids these issues entirely, providing a long service life with minimal maintenance. Its sealed design also prevents odours from escaping the tank, a critical consideration for black water installations.\u003c\/p\u003e \u003ch3\u003eApplications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eCaravan and motorhome fresh, grey, and black water tanks\u003c\/li\u003e \u003cli\u003eMarine holding tanks and potable water systems\u003c\/li\u003e \u003cli\u003eOff-grid cabins and tiny homes with limited access for maintenance\u003c\/li\u003e \u003cli\u003eIndustrial process tanks requiring reliable level feedback\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eUpgrade Your Tank Monitoring Today\u003c\/h3\u003e \u003cp\u003eReplace unreliable float switches with the precision of capacitive sensing.
