Product Description
The TRANE sen01842 is a normally closed (NC), single-pole single-throw (SPST) liquid level sensor designed for use in HVAC refrigeration and condensate management systems. It monitors liquid levels and triggers a circuit response when the set threshold is reached, protecting equipment from overflow or dry-run conditions. Rated at 30 watts, 220 degrees F, and 50 psi, this sensor is built for the temperature and pressure demands found in commercial and residential HVAC applications. Installation is typically performed by licensed HVAC technicians as part of routine service or system commissioning.
This liquid level sensor is suited for HVAC condensate, refrigerant circuit, or fluid management applications where reliable normally closed switching is required. Its 50 psi pressure rating and 220 degrees F temperature rating make it appropriate for use in environments with elevated operating conditions. It is a factory-specified Trane part intended for use in Trane HVAC systems and equipment requiring OEM-grade sensor performance.
Key Features
- Normally closed (NC) SPST switching configuration for fail-safe level detection
- 30-watt power rating suitable for control circuit loads
- 220 degrees F temperature rating for high-temperature operating environments
- 50 psi pressure rating for pressurized fluid or refrigerant circuit use
- OEM Trane part for reliable fit and function in Trane equipment
Compatibility
Designed as an OEM-style replacement liquid level sensor for Trane HVAC systems and equipment. Consult Trane parts documentation to confirm fitment for your specific unit model.
Installation Notes
Installation should be performed by a licensed HVAC technician familiar with refrigeration and condensate systems. Always de-energize the unit and isolate the fluid circuit before removing or installing the sensor. Verify that system pressure is relieved to zero before breaking any connections. Follow all applicable local codes and manufacturer service guidelines during installation.
