Description

The MicroCal ensures that the frequent checking of thermometer accuracies is a simple routine operation.

The instrument is designed to simulate any chosen temperature, allowing standard K thermocouple thermometers to be tested, checked or recalibrated simply and quickly, without the need for additional specialised equipment or conversion tables.

The MicroCal 2 has 12 preset temperatures which can be modified and saved by the user. The factory default temperatures can be recalled at any time. The MicroCal 3 has 23 fixed temperatures. Both models feature a custom 10mm LCD display with alpha-numeric display line to prompt the user when changing parameters. Selectable °C/°F, auto off enable/disable and display contrast adjustment are also available.

Each MicroCal is supplied with a one metre PVC lead with miniature thermocouple connector and a five-point UKAS Certificate of Calibration. Each certificate indicates deviations from standards at the various check points.

Specifications

The MicroCal Thermocouple Simulators can be used for the following purposes:

Calibration of Thermocouples and Instrumentation:

• Accuracy Verification: The MicroCal 2 & MicroCal 3 will generate the precise electrical signal to mimic the output of K-Type thermocouples, at specific temperatures set by the user. By connecting the simulator to a thermocouple-based instrument, technicians can quickly verify the accuracy of the instrument’s readings.
• Troubleshooting: MicroCal 2 & MicroCal 3 simulators help identify issues with K-Type thermocouples or instrumentation. If the instrument doesn’t respond correctly to the simulated signals, it indicates a problem with the thermocouple, its wiring, or the instrument itself.
• Calibration of Temperature Transmitters: Many industrial processes use temperature transmitters to convert thermocouple signals into standard signals like 4-20mA. Simulators are essential for calibrating these transmitters to ensure accurate temperature readings.

Testing and Maintenance:

• System Verification: MicroCal Simulators can be used to test the entire temperature measurement system, including thermocouples, wiring, transmitters, and control systems, to ensure they are functioning correctly.
• Predictive Maintenance: By regularly testing with the MicroCal simulators, potential problems can be identified before they lead to costly downtime or inaccurate measurements.

Training and Education:

• Hands-on Training: Simulators provide a safe and controlled environment for technicians to learn about thermocouple behaviour, calibration procedures, and troubleshooting techniques.
• Students: Can utilise the MicroCal simulators to see how monitoring equipment respond, without the need to generate high temperatures, or risk damaging more expensive equipment.

Benefits of Using Thermocouple Simulators:

• Improved Accuracy: Regular calibration with simulators ensures accurate temperature measurements, which is critical in many industries.
• Reduced Downtime: By identifying and addressing problems proactively, simulators help minimize costly equipment downtime.
• Enhanced Safety: Accurate temperature measurements are essential for safety in many applications, such as in industrial processes and research environments.
• Cost-Effectiveness: Simulators can help reduce the overall cost of ownership by preventing costly equipment failures and ensuring compliance with industry standards.
