HewTech Electronics LLC’s RTS-100 controller reliably detects the phase change from vapor to liquid in LNG and other cryogenic fill lines. In two-line filling systems, a solenoid valve vents gas-vapor back to the source tank until liquid is detected. Once the sensor confirms liquid flow, the controller activates the fill relay, signaling readiness to begin fueling.
Key Features:
- 🌡️ Sensor: 1/8″ 304 stainless steel probe with Teflon-insulated cable for harsh environments
- 📦 Enclosure: IP54/65 (NEMA 4/5) rated with sealed tinted cover for LED and relay visibility
- 🔁 Relay Output: 10A SPDT contact
- 🔧 Calibration: One-time adjustment via screwdriver with LED feedback
- ⚠️ Failsafe: Alerts on sensor failure or malfunction
- 🔌 Power: 120/240VAC, 3W transformer-isolated; supplies low-voltage DC to grounded sensor
- 📏 Sensor Lengths: Customizable for varied applications
This is an example of a product designed for a specific requirement for LNG fueling station application.
