Honeywell SP3000-WR Probe

The Honeywell SP3000-WR is a specialized water-resistant temperature probe engineered for precision monitoring in high-moisture HVACR environments. This 2-inch stainless steel thermistor probe features a 5-foot lead wire, providing the necessary reach and durability for immersion or surface-mount applications where standard sensors fail due to moisture ingress. As the direct replacement for Honeywell 198212CA, the SP3000-WR maintains exact resistance-to-temperature curves, ensuring seamless integration with existing building automation systems and controllers. Contractors typically utilize this PT3000 sensor for chilled water loops, sump Monitoring, or discharge air temperature sensing in high-humidity ducts. The robust construction prevents electrical drift and ensures long-term signal stability across the full operating range. When replacing an obsolete legacy sensor, this Honeywell thermistor probe offers the exact specifications required to restore system calibration without the need for additional hardware or complex field adjustments.

Key Benefits

• Moisture Resistance: Specifically encapsulated PT3000 element designed to prevent failure in condensing environments.
• Direct Compatibility: Drop-in 198212CA replacement ensures 1:1 signal accuracy with legacy Honeywell controllers.
• Durable Construction: 2-inch probe length optimizes thermal transfer for rapid response times in fluid or air.
• Installation Versatility: 5-foot lead allows for flexible routing through conduits or around mechanical components.

Common Questions

Is the SP3000-WR compatible with my existing Honeywell controller?
Yes, if your system uses the 198212CA or requires a PT3000 ohm sensor, this is the designated field replacement. It is engineered to match the original resistance specs to maintain narrow-tolerance control.

Can this probe be used in direct immersion applications?
The probe is water-resistant and suitable for many moisture-heavy applications; however, always use a thermowell for high-pressure fluid lines to allow for serviceability and to ensure the longevity of the lead wire connection.

What are the wiring requirements for the 5-foot lead?
The SP3000-WR uses a standard two-wire configuration. For longer runs, ensure you use shielded twisted pair to prevent EMI interference from affecting the temperature reading.
