RTD Probe for HVAC Systems
The Tempco RTD00576 is a 100 Ohm platinum resistance thermometer designed for temperature monitoring in HVAC, food, pharmaceutical and packaging applications. Its three-wire Pt100 element provides stable, repeatable readings across a broad operating range. The probe is supplied new and ready for integration into control loops or data-logging equipment.
Suited for Duct and Appliance Monitoring
Engineers specifying sensors for air-handling units, ovens or process ductwork will appreciate the FEP-jacketed cable that resists moisture and chemical exposure. The bare-wire termination allows direct connection to transmitters or PLC inputs without proprietary connectors. Buyers needing a threaded immersion fitting, a shorter insertion length or a different resistance value should look at other models.
12 Inch Insertion with 392 °F Upper Limit
The 12 inch probe length reaches into ducts or vessels while the sensor withstands continuous exposure up to 392 °F (200 °C) and down to -18 °C. The eight-foot FEP cable gives ample routing slack to the control cabinet. Beyond the rated temperature the platinum element will drift, so the probe should not be used in higher-heat zones.

Questions about this item
What type of controller input is required for the three-wire RTD probe?
The probe uses a three-wire Pt100 RTD element, so the controller must accept a three-wire resistance input with a 100 ohm base resistance at 0 °C.
Can the FEP-jacketed cable operate in the same duct temperatures as older PVC probes?
The cable is rated to 392 °F, which is higher than typical PVC limits, so it can remain in ducts where older PVC-insulated leads would degrade.
How can I verify the probe reads correctly after wiring it to the controller?
Apply a known reference temperature to the tip and compare the controller reading to the expected resistance value for a Pt100 sensor at that temperature.
