The controller ensures consistent calibration conditions, which is critical for obtaining reliable and repeatable measurement results.

Working Principle of Oil Based Calibration Bath

The oil bath works by heating specialized thermal oil inside a controlled chamber. The heating system gradually raises the oil temperature to the desired set point while maintaining uniform heat distribution throughout the bath.

Temperature sensors or instruments under calibration are immersed into the heated oil medium. Due to the excellent thermal conductivity and uniformity of the oil, the sensors experience stable and homogeneous temperature conditions, allowing accurate comparison and calibration.

The built-in PID controller continuously regulates the heating cartridge to maintain the target temperature with high precision.

Simple & User-Friendly Operation

The TB-250 Oil Based Temperature Calibration Bath is designed for convenient operation, even for routine laboratory and industrial use.

Step 1 – Power ON

After switching ON the mains power supply, the PID controller displays:

• PV (Process Value): Actual bath temperature
• SV (Set Value): Desired temperature setting

This dual display system allows users to monitor both the current and target temperatures simultaneously.

Step 2 – Setting the Desired Temperature

Users can easily adjust the temperature set point using the front panel keys.

The controller enables digit-by-digit temperature setting using UP and DOWN keys for accurate parameter entry.

This simple interface ensures:

• Easy temperature programming
• Accurate set point adjustment
• Quick operation
• Minimal operator training

Step 3 – Temperature Confirmation

After selecting the desired temperature value, the set key confirms and activates the heating process.

The controller then begins regulating the oil bath toward the target temperature.

Step 4 – Auto Tuning Function

The controller includes an advanced Auto Tuning feature that automatically calculates optimal PID parameters for improved temperature control performance.

During auto tuning:

• The controller performs controlled ON/OFF heating cycles
• The system calculates PID values automatically
• Temperature stability improves significantly
• Overshoot is minimized

This function enhances calibration accuracy and operational efficiency.

Step 5 – Auto Tuning Cancellation

If required, users can manually cancel the auto tuning process through the controller settings.

This provides operational flexibility for different calibration conditions.

Step 6 – Stable Temperature Maintenance

Once the desired temperature is achieved, the controller maintains stable conditions using short heating pulses.

This intelligent heating control provides:

• High temperature stability
• Reduced fluctuations
• Accurate calibration conditions
• Improved repeatability

Stable temperature control is extremely important for precision calibration applications.

Step 7 – Rapid Cooling System

The calibration bath includes a cooling fan system for faster cooling of the heating block.

This helps reduce waiting time between calibration cycles and improves overall productivity.

Benefits include:

• Faster temperature reduction
• Reduced downtime
• Improved workflow efficiency
• Convenient multi-point calibration

Excellent Temperature Uniformity

Uniform temperature distribution is one of the most important factors in calibration accuracy.

The oil medium inside the bath ensures:
