💧 SHT 8800 – Active water sensor with V4A stainless steel contacts

The SHT 8800 is a high-quality active water sensor with two robust V4A stainless steel contacts, encapsulated in a durable plastic housing with Wepuran®. As soon as water or another conductive liquid touches the contacts, the output voltage rises to approximately 80–90% of the operating voltage. This allows for easy and reliable control of high-impedance analog inputs of home automation or building management systems.

⚙️ Functionality and connection

  • The sensor cables (3 x 0.14 mm²) are flexible and can be easily extended (max. 20 meters).

  • Important: The connected analog inputs must be high-impedance to avoid loading the sensor.

  • An aluminum-reinforced drill hole facilitates secure fastening.

  • LIYY cables are temporarily waterproof, flame-retardant, low-adhesion, self-extinguishing, and resistant to oils, greases, coolants, and lubricants.

🚫 Not compatible with Schabus water detectors

The SHT 8800 is not suitable for direct connection to Schabus water detectors . Please note this during integration.

🤖 Active sensors – sensitive technology with auxiliary energy

Active sensors such as the SHT 8800 have an electronic internal component and always require auxiliary power – either through an operating voltage or a bias current to query a potential-free contact.

  • The SHT 8800 reacts to water contact with an increase in voltage.

  • Other active sensor types (e.g. SHT 8815 , SHT 8824 ) react differently (change in resistance or current).

  • Each sensor type is specifically tailored to the requirements of the respective control system.

💡 Sensitivity and area of ​​application

  • Active sensors are more sensitive than passive sensors and can also detect water with low conductivity.

  • Chemically pure, repeatedly distilled water cannot be reliably detected even by active sensors – at least some free ions must be present.

  • Suitable for regularly dry environments with rare water events.

  • In permanently humid environments, electrolysis can cause contact corrosion because the sensor operates with direct current.

🔧 Tips for a long service life

  • The high-impedance query of the sensor signals is a prerequisite for long and wear-free operation.

  • The current limit in the sensor protects against excessive wear.

FAQ - Frequently Asked Questions

💡 What is the difference between active and passive water sensors?
Active sensors like the SHT 8800 have electronic components and require an operating voltage. They react to water contact with a change in output voltage (e.g., from low to high). Passive sensors, on the other hand, operate purely mechanically or conduct current directly upon contact with water.

⚠️ Can the SHT 8800 be used with Schabus water detectors?
No, the SHT 8800 isnotCompatible with water detectors from Elektrotechnik Schabus. It is specifically designed for control systems with high-impedance analog inputs (e.g., smart home systems or building management systems).

🔌 What does “high impedance input” mean?
A high-impedance input loads the sensornot measurable, that is: The sensor mayonly need to deliver minimal power– typically typical for TTL or CMOS logic. Stress can damage the sensor or produce inaccurate readings.

📏 How far can I extend the cable?
The sensor cable (3 × 0.14 mm² LIYY) can be extended without any problem – but ideally not more than approx.20 metersto maintain signal stability and voltage level.

💧 Does the SHT 8800 also react to distilled water?
Only to a limited extent. The sensor requires aconductive liquid, i.e. water withsufficient free ions.Demineralized or repeatedly distilled watercannot be reliably detected. The medium should have at leastDensity of 0.7 g/cm³and have a certain conductivity.

🌊 Is the sensor suitable for permanently humid environments?
No. The SHT 8800 is fordry normal environmentswithoccasional water contactIn permanently humid environments, electrolysis can lead toCorrosion of the contactsbecause the sensor works with direct current.

🧪 Which liquids can the sensor detect?
The SHT 8800 recognizes allconductive liquids, e.g. tap water, salt water or cooling liquids. Not recognizable arenon-conductive mediasuch as distilled water or oils.

🧰 How is the sensor mounted?
The sensor is mounted so that the two V4A stainless steel contacts are located at the lowest point to be monitored. A defined installation position is not necessary, as it reacts directly to liquid contact.

👉A notice:For permanent and secure placement, the sensor shouldpermanently mounted– for this purpose, the aluminum base carrier has a suitableDrill hole for screwingprovided.
