If you rely on precise temperature control for your industrial or laboratory processes, Watlow's F4T® PID temperature controller and D4T™ digital temperature controller and data logger offer industry-leading solutions. Now, upgrading your F4T or D4T has never been easier—boost performance and unlock powerful new features with a simple software code.
Whether you're in Los Angeles, Houston, Chicago, or anywhere in the U.S., upgrading your PID temperature controller or digital temperature controller helps you maintain efficiency, compliance, and accuracy in your thermal systems.
Why Upgrade Your Watlow® Temperature Controller?
Watlow’s F4T temperature and process controller is a powerful, flexible, and highly configurable PID controller, while the D4T data logger provides comprehensive data tracking with field-removable I/O modules for ultimate design flexibility. With a new software upgrade, you can now add advanced features to both devices—no new hardware required.
Upgrades are easily installed through the Watlow COMPOSER® software with an activation code delivered via email from your Watlow representative.
Key Upgrade Features for F4T and D4T Temperature Controllers
1. Enhanced Data Logging with Optional Encryption
With the data logging upgrade, both the F4T PID temperature controller and D4T digital temperature controller can automatically save process data to internal memory or an external USB flash drive. This includes:
-
Time-stamped data for traceability
-
User-selected parameters
-
Optional encryption for secure data handling
This feature is especially valuable for regulated industries or applications requiring documented process control.
2. Add Real-Time Trending Charts
Visualize system performance directly on your digital temperature controller with trending charts.
-
View up to four charts with six customizable trend lines each
-
Export graphical data for reports or compliance audits
-
Monitor temperature fluctuations and system behavior in real-time
3. Add Function Blocks for Customized Control
Function blocks let users tailor the control logic of their PID temperature controllers or data loggers:
-
Basic upgrade includes more alarm blocks (beyond the default six)
-
Add timers, counters, mathematical and logic functions
-
Ideal for automated temperature or process control
For example, a user monitoring a critical temperature range can use additional alarm blocks to ensure consistent performance.
4. Add Ramp and Soak Profile Programming (F4T Only)
If your F4T temperature controller doesn't already include ramp and soak profiling, this upgrade adds it with ease.
-
Program a temperature increase (ramp), hold (soak), and decrease cycles
-
Automate thermal processes like heat treatment, curing, or testing
-
Enhance repeatability and precision in temperature-sensitive operations
5. Expand Control and Cascade Loops (F4T Only)
Need more control? This upgrade increases the number of control and cascade loops supported by your F4T PID controller.
-
Ideal for multi-zone systems or advanced process applications
-
May require additional hardware like flex modules and wiring
-
Enable precise control across complex systems
