Honeywell LP914A1144 Temperature Sensor

The Honeywell LP914A1144 is a professional-grade pneumatic temperature sensor engineered for precision sensing in commercial HVAC air handling units and ductwork. This single-pipe pneumatic controller utilizes a high-sensitivity rod and tube sensor element with a 15-inch insertion length, ensuring accurate thermal detection across a wide 25-125 degree Fahrenheit sensing range. As a direct-acting pneumatic sensor, it provides a proportional 3-15 PSI output signal relative to temperature changes, allowing for seamless integration with pneumatic actuators and dampers. The LP914A1144 duct mount sensor is constructed with a corrosion-resistant finish, making it a reliable choice for high-humidity environments or air streams with chemical particulates. This model is functionally identical to the LP914A1144/U, offering a drop-in solution for legacy systems requiring a proportional pneumatic thermostat or remote sensing probe. Its robust mechanical design eliminates electronic interference, providing stable HVAC pneumatic control in demanding industrial applications.

Key Benefits for Contractors

• Broad Compatibility: Operates as a standard 1-pipe direct-acting device compatible with most Honeywell pneumatic systems and multi-brand pneumatic loops.
• Extended Probe Length: The 15" sensing element allows for accurate core temperature readings in large diameter supply air ducts.
• Simplified Calibration: Features a straightforward linear output of 3-15 PSI for easy field testing and system balancing.
• Durable Construction: The rod and tube element is built to withstand mechanical vibration and airflow turbulence without losing setpoint accuracy.
• Reliable Performance: Completely pneumatic operation provides a non-electric temperature sensing solution for hazardous or spark-sensitive locations.

Common Questions

What is the difference between LP914A1144 and LP914A1144/U?
There is no functional difference; the "/U" suffix simply denotes a universally packaged version of the same 1-pipe pneumatic sensor.

Can this sensor be used for reverse-acting applications?
No, this specific model is a direct-acting sensor. For reverse-acting requirements, a pneumatic relay or a different sensor model would be necessary to invert the 3-15 PSI signal.

Is the mounting hardware included for duct installation?
The unit is designed for standard duct mounting, typically utilizing a flange or bracket compatible with Honeywell pneumatic hardware kits for 15-inch elements.
