Description
Bimetal Dial Thermometer 4″ Dial 0–300°C | 12″ Stem | Back Entry | 1/2″ BSP | Stainless Steel Case
Accurate temperature monitoring is essential in industrial processes where even a small variation can affect product quality, equipment performance, and operational safety. The Bimetal Dial Thermometer 4″ Dial 0–300°C with 12″ stem and back entry mounting is a reliable and durable temperature measuring instrument designed for demanding industrial environments.
Manufactured using high-quality stainless steel case and stainless steel wetted parts, this industrial bimetal dial thermometer provides long-lasting performance and accurate temperature readings across various applications. Its large 4-inch dial allows operators to read temperature values easily from a distance, making it ideal for industrial plants, manufacturing facilities, HVAC systems, and process industries.
The thermometer features a temperature range of 0 to 300°C, making it suitable for a wide variety of temperature monitoring applications involving liquids, gases, and steam. The 12-inch long stem with 10 mm outer diameter allows deeper insertion into tanks, pipelines, or vessels for more accurate temperature measurement.
High-Accuracy Industrial Temperature Measurement
The bimetal dial thermometer operates using a proven mechanical temperature sensing principle. Inside the thermometer, a bimetallic strip made from two different metals expands at different rates when exposed to temperature changes. This expansion causes the strip to bend and rotate the pointer on the dial, displaying the temperature reading instantly.
Because of this simple yet reliable design, bimetal thermometers do not require external power, making them ideal for remote installations and harsh environments where electrical devices may not be practical.
This model provides fast response, reliable readings, and long operational life, making it a preferred choice for engineers, technicians, and plant operators.
Large 4 Inch Dial for Clear Visibility
One of the key advantages of this 4 inch bimetal dial thermometer is its large display. The wide dial face ensures that temperature readings are easy to read even from a distance. In busy industrial environments where operators monitor multiple instruments simultaneously, a clear and visible display helps reduce errors and improves operational efficiency.
The dial is carefully calibrated to provide precise temperature readings within the 0–300°C range, ensuring consistent monitoring of critical processes.
Durable Stainless Steel Construction
Industrial environments often involve high humidity, chemical exposure, vibrations, and extreme temperatures. To ensure reliability under such conditions, this industrial bimetal thermometer is built with a stainless steel case and stainless steel wetted parts.
The stainless steel body offers several advantages:
- Excellent corrosion resistance
- Long service life in industrial environments
- Protection against dust and moisture
- Strong mechanical durability
This robust construction ensures the thermometer continues delivering accurate readings even in challenging conditions.
12 Inch Long Stem for Deep Temperature Sensing
The thermometer is equipped with a 12 inch long stem with 10 mm outer diameter, which allows the sensing element to reach deeper into pipes, tanks, and vessels. This is particularly useful for industrial processes where surface temperature measurement is not sufficient.
By inserting the stem deeper into the process fluid or gas stream, the thermometer provides more accurate temperature readings, improving overall process monitoring and control.
Back Entry Design for Direct Mounting
This thermometer features a direct mounting back entry design, making it suitable for installation in pipelines, reactors, boilers, tanks, and industrial equipment where vertical or panel mounting is required.
The back entry configuration ensures that the dial remains visible while the stem is installed directly into the process connection.
The instrument comes with a 1/2″ BSP male connection, which is a widely used standard in industrial piping systems. This allows easy integration into existing installations without additional adapters.
