Honeywell SP3000-2 Probe

The Honeywell SP3000-2 is a professional-grade PT3000 temperature sensor designed for precision monitoring in high-demand HVACR environments. This unit features a 2-inch stainless steel probe and 24-inch encapsulated leads, providing a reliable interface for Honeywell electronic controllers like the T775 Series, W7100, and W7620. Engineers and contractors frequently utilize this immersion temperature sensor for discharge air or liquid applications due to its platinum positive temperature coefficient (PTC) element, which ensures a linear resistance-to-temperature curve without the need for field calibration. With an expansive operating range of -40°F to 302°F, the Honeywell SP3000-2 probe is the standard direct replacement for 193987GA and 193987GA/U legacy components. Whether you are performing a strap-mounted sensor installation on a chiller or integrating it into a high-temp boiler loop, the 3484-ohm nominal resistance at 77°F guarantees the thermal accuracy required for tight process control and energy efficiency in commercial building automation systems.

• Broad Compatibility: Seamlessly integrates with T775, R7380J/L, and W7000 series controllers using standard PT3000 logic.
• Legacy System Support: Serves as the factory-authorized direct replacement for 193987GA, ensuring zero-gap maintenance for older installations.
• Durable Construction: The 2-inch probe is encapsulated for moisture resistance, making it suitable for both immersion wells and pipe-strap applications.
• Maintenance-Free: Factory calibrated with a platinum PTC sensing element that maintains accuracy over time without manual adjustments.
• Wide Thermal Envelope: Rated for extreme temperatures between -40°F and +302°F, covering almost all commercial HVACR scenarios.

Is the Honeywell SP3000-2 compatible with older 193987GA sensors?
Yes, the Honeywell SP3000-2 is the official direct replacement for lead-style sensors 193987GA and 193987GA/U, utilizing the same PT3000 resistance profile.

Can this probe be used in immersion applications?
Specifically designed for versatility, this immersion temperature sensor can be inserted into a standard well or strapped directly to discharge piping for accurate surface readings.

What is the resistance value of the PT3000 element?
The PT3000 2-inch probe operates with a nominal resistance of 3484 ohms at 77°F (25°C) and maintains a linear coefficient for simplified controller integration.
