Mild Steel Temperature Gauges

Temperature gauges provide a local visual display of temperature readings, often used in various industrial and commercial settings. Here's a breakdown of their typical specifications:

General Specifications

· Temperature Range: The range of temperatures the gauge can display (e.g., -40°C to +300°C).

· Temperature Dial: This displays the temperature scale (e.g., Celsius or Fahrenheit) and markings for the measurable temperature range.

· Pointer: This indicates the measured temperature on the temperature dial.

Performance Specifications

· Accuracy: Expressed as a percentage of full scale (%FS) or in temperature units (°C or °F). Typical accuracy for good quality gauges is ±2%FS to ±5%FS. Dial thermometers generally have lower accuracy than digital thermometers.

· Response Time: The time it takes for the gauge to reflect a change in temperature (usually slower than electronic thermometers, ranging from seconds to minutes).

Additional Features

· Stem Length: The length of the metal part inserted into the medium to measure temperature. Choose a stem length that reaches the point of desired temperature measurement within the process or environment.

· Material of Construction: The materials used in the gauge housing, stem, and dial. Common materials include stainless steel, brass, and plastic. The selection depends on factors like temperature range, pressure resistance, and corrosion potential of the environment.

· Fill Material (Liquid Filled Gauges): Some gauges are filled with a liquid (often glycerin or silicone oil) to dampen vibrations and improve pointer movement readability.

· Max/Min Recording (Optional): A feature in some gauges that tracks and displays the highest and lowest temperatures recorded.

· Alarm (Optional): Certain models can be equipped with alarms to trigger at pre-set high or low-temperature thresholds.

Environmental Specifications

· Ambient Temperature Range: The range of surrounding temperatures the gauge can function within without compromising performance.

· Ingress Protection (IP rating) (Optional): A rating for some gauges indicating their resistance against dust and water ingress (e.g., IP54 for dust resistance and splash water protection).

Factors to Consider When Selecting a Temperature Gauge

· Temperature Range: Choose a gauge with a range that covers the entire temperature spectrum you intend to monitor.

· Accuracy: Select a gauge with accuracy suitable for your application's requirements. Dial thermometers may be sufficient for non-critical applications where high precision isn't essential.

· Response Time: Consider how quickly you need the gauge to reflect temperature changes in your application.

· Stem Length: Choose a stem length that reaches the appropriate measurement point within your process or environment.

· Material of Construction: Select materials compatible with the temperature range, pressure, and potential corrosive elements in your application.

· Additional Features: Consider optional features like max/min recording, alarms, or an IP rating based on your needs.

By understanding these specifications and factors, you can select a temperature gauge that provides a clear and reliable visual indication of temperature for your monitoring applications.
