Robertshaw 2374-499 Pressure Switch
The Robertshaw 2374-499 Pressure Switch is a high-performance adjustable pressure switch designed for critical monitoring of air or non-combustible gases in commercial HVAC and refrigeration systems. Engineered with a wide operating temperature range of -40°F to 190°F, this SPDT pressure switch provides versatile control for differential, vacuum, or positive pressure applications. Its adjustable set point allows technicians to fine-tune the pressure actuation levels to ensure precise system cycling and safety compliance. Constructed with a durable glass-filled polycarbonate housing and a silicone diaphragm, this unit handles HVAC system pressure monitoring with long-term reliability. Whether utilized for fan proving switches or clogged filter detection, the Robertshaw 2374-499 offers the rugged build quality required for demanding field environments, ensuring seamless integration into existing control circuits without compromising sensitivity or accuracy during field calibration.
Key Benefits for Technicians:
- Wide Operating Range: Rated for extreme environments from -40°F to 190°F, making it suitable for both refrigeration and high-heat applications.
- Field Adjustable: Features an accessible adjustment screw for precise differential pressure settings tailored to specific system requirements.
- Versatile SPDT Contacts: The Single Pole Double Throw configuration allows for normally open or normally closed operation, facilitating flexible wiring for alarms or motor controls.
- Rugged Construction: Built with a heavy-duty housing and high-quality diaphragm to resist environmental stressors and mechanical fatigue.
- Universal Mounting: Designed for easy installation in various orientations to accommodate tight furnace or air handler cabinets.
Commonly Asked Questions:
What is the maximum pressure rating for the Robertshaw 2374-499?
This switch is typically rated for a maximum pressure of 0.5 psi (13.85 in. w.c.), ensuring it can handle standard commercial air handling pressures without damage to the diaphragm.
Can this switch be used for water pressure applications?
No, the 2374-499 is specifically designed for air and non-combustible gases. Using it with liquids will damage the internal sensing elements and void the operational reliability.
How do I calibrate the set point in the field?
Calibration is performed using the adjustment screw located on the housing. It is recommended to use a calibrated manometer to verify the exact actuation and de-actuation points during the setup process.
