Fenwal 01-017023-000 Thermoswitch
The Fenwal 01-017023-000 Thermoswitch is a high-precision cartridge type temperature control engineered for demanding industrial HVACR applications. Operating on the differential expansion principle, this strut-and-tube thermostat utilizes a 300 series stainless steel shell as the active sensing element, ensuring a nearly instantaneous response to thermal shifts. Designed for a broad temperature control range of -100°F to 600°F, this unit is configured to close on rise, making it an ideal choice for over-temperature protection or circuit activation in high-heat environments. With a compact 0.625" diameter and 10" wire leads, the Fenwal 17023-0 integrates seamlessly into existing probe-style assemblies. Its mechanical, unpowered design provides a narrow differential and extreme sensitivity, maintaining 0.1°F resolution without the need for external power supplies. For contractors requiring a vibration resistant and durable stainless steel thermal switch, this Fenwal component delivers consistent performance in extreme conditions.
Key Benefits
- Extreme Thermal Sensitivity: Achieves a resolution of 0.1°F, allowing for precise temperature regulation in critical processes.
- Rugged Stainless Steel Construction: The 300 series stainless steel shell and head provide superior corrosion resistance and durability in harsh environments.
- High Vibration Resistance: The robust strut-and-tube internal assembly is designed to withstand mechanical stress better than standard bimetallic switches.
- No Power Supply Required: Operates as a purely mechanical temperature controller, simplifying field wiring and increasing reliability.
- Versatile Mounting: The 0.625" cartridge type design is compatible with standard thermowells for hazardous or high-pressure locations.
Common Questions
How does the "close on rise" logic affect my system wiring?
In this configuration, the internal contacts remain open until the setpoint is reached. Upon a temperature increase to the threshold, the circuit completes. This is typically used to trigger cooling fans, alarms, or safety shutdowns.
Can I use this Fenwal thermoswitch in liquid immersion applications?
Yes, but it is standard practice for technicians to utilize a compatible Fenwal thermowell (such as the 80016 series) to protect the probe from high pressure or corrosive fluids while maintaining fast thermal transfer.
Is the temperature setpoint adjustable on the 01-017023-000?
Yes, this model features an internal adjusting sleeve. Pro-tip: For precise calibration, use a controlled thermal bath and a calibrated thermometer, as small rotations of the sleeve result in significant setpoint changes.
