Core Technical Advantages
-
High-Reliability Switching: The unit features a hermetically-sealed switch with gold contacts. Combined with a precision knife-edge sensing mechanism, this ensures highly accurate level detection and a long operational life even in corrosive atmospheres.
-
Vibration Immunity: The L2e is specifically engineered for high-vibration applications, such as compressor scrubbers. The force-balanced sensor design ensures the switch remains stable and does not chatter or trigger false signals due to mechanical interference.
-
Leakage-Free Performance: Advanced design and premium components ensure there is no leakage current, providing a clean electrical signal for your control system or SCADA network.
-
NACE Compliance: Standard construction utilizes materials that comply with NACE MR0175-2002 requirements, making it safe and durable for sour gas (H2S) service right out of the box.
-
Instant Technical Support: A QR code is located inside the cover, providing technicians with immediate access to wiring diagrams, calibration procedures, and troubleshooting guides directly in the field.
