<h2 data-start="337" data-end="415"><strong data-start="340" data-end="415"> 💧 SHT 5002 – Intelligent level control & overflow detection in one device</strong></h2>
<p data-start="417" data-end="855">The <strong data-start="421" data-end="433">SHT 5002</strong> is more than just a water detector – it's a powerful <strong data-start="494" data-end="551">2-point level controller with an additional overflow warning, ideal for DIN rail mounting in a fuse box or small distribution board. Thanks to two separate detection lines, several functions can be implemented simultaneously: the precise <strong data-start="747" data-end="790">filling or emptying of a container</strong>, as well as independent <strong data-start="813" data-end="854">monitoring for overflow or leakage.</p>

<h3 data-start="862" data-end="908"><strong data-start="866" data-end="908">🛡️ Two reporting lines – double security</strong></h3>
<h4 data-start="910" data-end="959"><strong data-start="915" data-end="959">⚙️ 1. Level control with float switches</strong></h4>
<p data-start="960" data-end="1385">The first detection line handles the actual <strong data-start="1007" data-end="1030">level control: Two miniature float switches define an upper and a lower level in the tank or container. Depending on the desired function – <strong data-start="1159" data-end="1171">filling</strong> or <strong data-start="1177" data-end="1190">emptying</strong> – the device controls a connected pump via a <strong data-start="1246" data-end="1283">potential-free 5 A changeover relay. Switching occurs automatically as soon as the water level reaches one of the specified levels.</p>

<h4 data-start="1387" data-end="1440"><strong data-start="1392" data-end="1440">🚨 2. Overflow detector – independent & reliable</strong></h4>
<p data-start="1441" data-end="1860">The second detection line operates independently of the level control and triggers as soon as water is detected at an additional float switch (i.e., the third one). This allows a potential overflow to be reliably detected, for example, in the event of a pump failure or an unexpected inflow. Here, too, a dedicated relay ensures direct control of signaling devices, alarm systems, or emergency valves.</p>

<h3 data-start="1867" data-end="1924"><strong data-start="1871" data-end="1924">🔁 Filling or emptying? Easily switch between options</strong></h3>
<p data-start="1926" data-end="2076">With a <strong data-start="1936" data-end="1961">simple wire jumper</strong> you can specify whether the system should <strong data-start="2018" data-end="2032">refill</strong> when the water level is low or <strong data-start="2057" data-end="2070">drain</strong> when the water level is too high:</p>

<ul data-start="2078" data-end="2371">
<li data-start="2078" data-end="2212">
<p data-start="2080" data-end="2212"><strong data-start="2080" data-end="2103">Filling function</strong>: If the water level drops below the lower level, the relay activates the pump until the upper level is reached.</p>
</li>
<li data-start="2213" data-end="2371">
<p data-start="2215" data-end="2371"><strong data-start="2215" data-end="2239">Drain function</strong>: If the water level exceeds the upper level, the device starts the pump until the water drops below the lower level again.</p>
</li>
</ul>
<p data-start="2373" data-end="2493">This intelligent control not only saves effort, but also reliably protects against dry running or overfilling.</p>

<h3 data-start="2500" data-end="2550"><strong data-start="2504" data-end="2550">🧪 Ideal for a wide variety of liquids</strong></h3>
<p data-start="2552" data-end="2994">In combination with the robust <strong data-start="2584" data-end="2638">mini float switches from Elektrotechnik Schabus</strong>, the SHT 5002 is also suitable for <strong data-start="2665" data-end="2713">non-conductive or hazardous liquids</strong> – including oils, diesel, or distilled water. Important: While water sensors are more universally applicable, they are less precise and more prone to false alarms – especially in constantly humid environments. For precise cut-off points, we clearly recommend the <strong data-start="2974" data-end="2993">float solution</strong>.</p>

<h3 data-start="3001" data-end="3057"><strong data-start="3005" data-end="3057">🏞️ Flexible applications – from ponds to technical rooms</strong></h3>
<p data-start="3059" data-end="3399">Whether it's a rainwater tank, livestock trough, pool, or machine sump: The SHT 5002 ensures reliable control wherever levels need to be regulated or overflows prevented. Even two completely independent applications simultaneously are possible – e.g., a level controller in a cistern insert and an overflow alarm under a washing machine.</p>

<h3 data-start="3406" data-end="3450"><strong data-start="3410" data-end="3450">💡 Convenient display &amp; reset function</strong></h3>
<p data-start="3452" data-end="3516">Two LEDs clearly indicate the status of both detection lines:</p>

<ul data-start="3518" data-end="3699">
<li data-start="3518" data-end="3603">
<p data-start="3520" data-end="3603"><strong data-start="3520" data-end="3541">Green LED (S1–S2)</strong>: lights up when the pump is deactivated, flashes when the pump is active</p>

<li data-start="3604" data-end="3699">
<p data-start="3606" data-end="3699"><strong data-start="3606" data-end="3630">Red LED (S3)</strong>: flashes when water is detected, lights up continuously after manual reset</p>
</li>
</ul>
<p data-start="3701" data-end="3889">The integrated <strong data-start="3717" data-end="3759">storage function for overflow messages</strong> ensures that alarm messages are retained until they are specifically acknowledged – ideal for safety-critical applications.</p>

<h3 data-start="3896" data-end="3953"><strong data-start="3900" data-end="3953">🪝 Float instead of sensor? No problem installing!</strong></h3>
<p data-start="3955" data-end="4324">Would you prefer to use sensors because you can't drill into your tank? Understandable – but we have a better solution: our <a href="https://www.elektrotechnik-schabus.de/warnsysteme-wasser/haenge-schwimmerschalter-kunststoff"><strong data-start="4108" data-end="4135">suspension float switch (item 200950)</strong></a> with counterweight. This is simply inserted from above, always remains reliably vertical in the medium, and can be continuously adjusted in height using the included PG screw connection.</p>
