TXC Capillary Dial Temperature Gauge Sensor

What is a Temperature Gauge?

A temperature gauge is an instrument or device used to measure and display the temperature of a system or environment. It provides a visual or numerical representation of the temperature reading, allowing for easy monitoring and assessment of temperature levels. Temperature gauges come in various forms, including analogue and digital displays. Analogue temperature gauges typically use a mechanical system, such as a bimetallic strip or a liquid-filled bulb and capillary, to translate temperature changes into physical movements that are then visually displayed on a dial or scale.

What is a Capillary Temperature Gauge Sensor?

A capillary temperature gauge sensor is a type of temperature sensor that utilises a capillary tube filled with a temperature-sensitive fluid to measure temperature changes. It consists of a bulb or sensing element connected to a capillary tube and a gauge or dial for temperature readings. The sensing element, usually containing a gas or liquid, expands or contracts with temperature variations. This expansion or contraction causes the fluid in the capillary tube to move, exerting pressure on a diaphragm or spring mechanism. This pressure is then translated into a temperature reading on the gauge or dial. The capillary tube provides a pathway for the fluid to transfer temperature changes from the sensing element to the gauge. The length and diameter of the capillary tube can vary, allowing for different installation configurations and applications. Capillary temperature gauge sensors are commonly used in applications where direct contact with the measured object is not feasible or desired. They are found in various industries, including HVAC systems, refrigeration, automotive, and industrial processes, providing a reliable and mechanical means of temperature measurement.

Temperature Gauge vs Thermometer

A temperature gauge and a thermometer are both devices used for measuring temperature, but they differ in their design, purpose, and usage. A temperature gauge is typically a device with a visual display that provides continuous monitoring of temperature levels in a system or environment. It often features a dial, scale, or digital readout to indicate the temperature. Temperature gauges are commonly used in industrial settings and are designed for long-term monitoring and offer real-time temperature readings. Whereas, a thermometer is a general term referring to any device used to measure temperature. Thermometers can come in various forms, such as liquid-filled, digital, or infrared thermometers. They are often handheld and used for spot measurements of temperature in a specific location or on a particular object.

What are the different types of temperature gauges available in the UK?

Numerous types of temperature gauges are for sale online in the UK. Traditional dial thermometers, like bourdon tube and spiral tube models, are popular. For automotive use, options include car’s temperature gauges monitoring coolant temperature, oil pressure, and expansion temperature gauges. Additionally, thermocouples and glass thermometers are available, catering to various industrial and scientific needs, with different accuracy classes and calibration options.

What are analogue thermometers and how do they work?

Analogue thermometers measure temperature using physical changes. Traditional dial thermometers, like those in cars monitoring water temperature, operate on the expansion principle. A bourdon tube or spiral tube filled with inert gas expands with heat, moving a needle on a calibrated scale. This mechanical measuring system converts the thermal state of a homogeneous substance into a readable format, without needing electrical signals or wiring, in accordance with basic thermodynamic principles.
