Compact flow monitor (with sensor) RLSW5A with analog output (0 ... 10 V + 4 ... 20 mA), measurement range for gases: 0.1 … 30 m/s
Description
Description
✅ TÜV NORD-certified RLSW5A analog airflow sensor with dual parallel outputs (0–10 V and 4–20 mA) for continuous fan control at 0.1–30 m/s
✅ Calorimetric dual-resistor system with 30 K/min temperature gradient tolerance and ±10% measurement accuracy, ±1% reproducibility
✅ Gain potentiometer for custom analog range adjustment: e.g., 5 m/s nominal flow rate = 5 V/10 mA output signal
✅ Automatic current/voltage coupling: 0–10 V (Ra = 10 kΩ) + 4–20 mA (Ra = 0.2 kΩ) coupled without requiring separate calibration
✅ Dual power supply: 24 V AC/DC or 230 V AC for direct connection in control cabinets without a power supply unit and without low-voltage requirements
✅ Rugged IP67 sensor system with MS58 nickel-plated housing (stainless steel or Teflon available as options) for media temperatures 0–70°C
✅ 6-terminal connection, 2.5 mm², for 4-wire wiring - **CAUTION: Never bridge N(-) and U-/-Ia (will destroy the device!)**
✅ Six immersion depths available: 50, 130, 165, 300, 400, 500 mm for optimal adaptation to various duct sizes
✅ Versatile process connections: PG7 standard, G1/2" via reducer, separate mounting flange for duct installation
✅ Control applications: Frequency converter control, SCADA visualization, DDC building automation, process control
✅ Maintenance-free technology with no moving parts vs. mechanical paddle systems; can be cleaned with soapy water at lukewarm temperatures
⚠️ Important: Pure analog output without relay switching function—for monitoring, select RLSW5 with SPDT changeover contact
Iout (-) must not be connected to the negative terminal of the supply voltage, nor to ground or earth.
The power supply to the downstream evaluation unit (e.g., PLC) must be galvanically isolated and must not establish a ground connection.
If necessary, a power isolator must be used.
