💧 SHT 8824 – Active water sensor with current evaluation

For 2-wire power interfaces with precise wet/dry detection


⚙️ Reliable water detection via current consumption

The SHT 8824 is a compact, active water sensor with two V4A stainless steel contacts and a potted housing made of Wepuran® plastic .
It works as a constant current sink :

  • Dry operation: approx. 4 mA

  • Wet operation: approx. 20 mA

➡️ This current change allows a clear distinction between “dry” and “wet” – ideal for controllers with a 2-wire interface.


🧪 High sensitivity – even detects DIY store distillate

The sensor is extremely sensitive:
✅ Even simple distilled water according to VDE 0510-5 (e.g. from the hardware store) is reliably detected.
The technology only reaches its limits when it comes to completely ion-free ultrapure water.


🏠 Ideal for:

  • Home automation with analog power input

  • PLC or BMS with 2-wire sensor inputs

  • Applications with increased recognition requirements

  • Only suitable for dry environments – permanent humidity can cause corrosion through electrolysis


📦 Equipment & Materials

  • Two V4A stainless steel contacts

  • Wepuran®-encapsulated plastic housing

  • LIYY cable : temporarily waterproof, flame-retardant, self-extinguishing, resistant to oils and greases

  • Mounting hole for fixed floor mounting available


🚫 Not compatible with Schabus water detectors

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

WEEE NO.: DE91394868

Operating voltage 10…30 VDC, typ. 24 VDC, SELV/PELV
Functional area -15°C / +50°C
Protection class IP 68, protection against water jets for 30 minutes, cable temporarily waterproof
Dimensions (W x W x D) 34x12x10 mm
Load resistance / burden up to 500 Ω at Ub < 24 VDC, up to 700 Ω at Ub >= 24 VDC
Line 2-wire – LIYY – 2x 0.14mm² – unshielded – Ø 3.5mm – white – 4 meters long, pinout: white – negative connection / 0 V / minus; brown – positive connection / Ub / plus
material ABS, aluminum, V4A stainless steel contacts, Wepuran® plastic, hand-cast

Instructions for use

CE declaration / EU declaration of conformity

🔌How does the SHT 8824 water sensor work?

The SHT 8824 detects water via a change in current consumption:

  • Dry operation:approx. 4 mA
  • Wet operation:approx. 20 mA
    This current difference is clearly evaluated by 2-wire inputs (e.g. current interfaces in BMS or PLC).

⚙️What is the sensor particularly suitable for?

The sensor is ideal for:

  • Home automation
  • PLC or BMS systems with 2-wire interface
  • Applications with precise wet/dry differentiation
  • Controllers that evaluate an analog current input

⚠️Can I connect the sensor to a Schabus water detector?

No.The SHT 8824 isnot compatiblewith Schabus water detectors.
It requires a control system withactive 2-wire current interface, since he isConstant current sinkworks.

💧How sensitive is the sensor?

The SHT 8824 even detects distilled water according to VDE 0510-5 (e.g. from the hardware store).
Only completely deionized ultrapure water remains invisible to it – a few free ions must be present.

🧪Is the sensor suitable for permanent humidity?

❌ No. The sensor is forregularly dry environmentsthought.
Atconstant moistureit can be converted intoCorrosion of the contactscome.

🔧How is the sensor mounted?

The sensor has aintegrated boreholefor thefixed floor mounting.
Mounting material is included in delivery.

📏What is the maximum length of the supply line?

The sensor cable (2 x 0.14 mm², e.g. LIYY) mayup to 20 metersbe extended.
Please ensure a good connection and clean cable path.
