Temperature and dry well calibrators

Frequently asked questions about temperature calibration

What is a temperature calibrator?

A temperature calibrator is a specialized tool designed to verify and adjust the accuracy of temperature-measuring devices like thermocouples, resistance temperature detectors (RTDs), and infrared thermometers. It creates a controlled temperature environment where these instruments can be tested and calibrated to ensure their readings are precise and reliable. Temperature calibrators are crucial in maintaining the accuracy of temperature measurements across various industries, including manufacturing, pharmaceuticals, and food processing.

What does a temperature calibrator do?

A temperature calibrator is a device used to test and adjust the accuracy of temperature measurement instruments. These calibrators generate precise temperature conditions that enable technicians to compare and adjust the readings of a device under test (DUT), ensuring their accuracy and reliability. This process helps maintain the integrity of temperature measurements in various industrial applications.

What instrument is used for temperature calibration?

Several instruments are used for temperature calibration, depending on the specific requirements of the calibration task. Commonly used instruments include:

• Temperature calibrators: These can be dry-block calibrators, liquid baths, or infrared calibrators that provide stable temperature sources for calibration.
• Reference thermometers: High-accuracy thermometers are used as a standard for comparison during calibration.
• Thermocouples and resistance temperature detectors (RTDs): Sensors are often calibrated to ensure their readings match the reference standard.

What are the different types of temperature calibrators?

Temperature calibrators come in various forms to suit different calibration needs:

1. Dry-block calibrators: These devices provide a stable temperature environment by heating or cooling a metal block into which the sensor is inserted for calibration.
2. Liquid bath calibrators: Using a liquid medium to create a uniform temperature environment, these calibrators are ideal for calibrating sensors that require immersion.
3. Infrared calibrators: These calibrators provide a stable infrared radiation source and are designed for non-contact temperature measurement devices.
4. Portable temperature calibrators: Compact and easy to carry, these calibrators are perfect for on-site calibration tasks, ensuring flexibility without compromising accuracy.

What equipment is used for temperature calibration?

The primary equipment used for temperature calibration includes:

• Dry-block calibrators: Generate stable temperatures in a metal block.
• Liquid bath calibrators: Use liquids like oil or water for immersion-based calibration.
• Infrared calibrators: Calibrate non-contact temperature measurement devices.
• Reference thermometers: High-precision thermometers used as calibration standards.
• Thermocouples and RTDs: Sensors that require regular calibration to ensure accurate readings.
• Portable temperature calibrators: These are versatile and mobile solutions for on-site calibration.

What is a thermocouple calibrator?

A thermocouple calibrator is an instrument used to verify and adjust the accuracy of thermocouples and thermocouple measurement systems. These devices are used in industries where precise temperature measurement is critical, such as manufacturing, pharmaceuticals, and energy production. A thermocouple calibrator ensures that temperature sensors and transmitters deliver reliable and accurate readings by providing accurate sourcing and measurement of various thermocouple types and millivolt.

Thermocouple calibrators like the Fluke 714B are designed for high accuracy and ease of use. The Fluke 714B is a handheld, battery-operated instrument capable of calibrating linear thermocouple transmitters with its millivolt (mV) source function and measuring milliamps (mA) while sourcing temperature. It offers features such as a linear ramp and 25% step auto ramp functionality for quick linearity checks, making it a versatile tool for calibration professionals.

What is a Dry Block Calibrator Used For?

A dry block calibrator ensures the accuracy of temperature measurement devices, such as sensors and thermometers. It provides a stable and uniform temperature environment, allowing for precise calibration. This tool is essential in industries like pharmaceuticals, food and beverage, manufacturing, and HVAC systems, where maintaining accurate temperature control is critical for quality, safety, and regulatory compliance.
