• Bimetallic temperature sensing element: Commonly made of nickel-chromium alloy + iron-nickel alloy combination, with a temperature range of -50 to 800℃, determining the basic temperature measurement accuracy and stability.
• Signal processing module: Integrated with amplification, filtering, and AD conversion circuits to ensure signal stability, with a display resolution of up to 0.1℃.
• Digital display screen: LCD screen (low power consumption, suitable for battery power supply) or LED screen (high brightness, suitable for strong light environments), with a dial diameter of φ60 to φ150mm.
• Power supply unit: Divided into built-in battery (lithium battery / dry battery, with a battery life of 1 to 5 years) and external power supply (DC 24V / AC 220V) two types.
• Protective casing: Materials can be selected from carbon steel, 304/316L stainless steel, and Hastelloy, with a wall thickness of 3 to 5mm, a pressure resistance of ≤25MPa, and a protection level of IP65 to IP67.

• Digital Direct Reading: The temperature value is directly displayed, with clear readings that avoid human errors, especially suitable for low-light or long-distance observation.
• Simple and Reliable Structure: It retains the mechanical temperature-sensing principle of bimetallic thermometers, is resistant to vibration and shock, and has good durability.
• No External Power Supply Required (for some models): Some purely mechanical digital display models are driven by mechanical energy, which is intrinsically safe and suitable for explosion-proof environments.
• Wide Application Range: It can measure the temperature of liquids, gases, and steam within the range of -80℃ to +500℃, covering most industrial scenarios.
• Flexible Installation: Supports various installation methods including axial, radial, and universal types, adapting to complex on-site conditions.

1. Measuring range: Conventional type -50℃ to 500℃, high-temperature type up to -80℃ to 800℃, low-temperature type down to -100℃ to 100℃.
2. Accuracy grade: Industrial grade 1.0 (commonly used), precision grade 0.5, superior to traditional pointer-type bimetallic thermometers.
3. Display parameters: Resolution 0.1℃/1℃ (switchable), refresh rate 1 to 2 times per second, LCD screen supports backlight (for some models).
4. Power supply and power consumption: Battery-powered type static power consumption ≤ 10μA, battery life 1 to 5 years; external power type power consumption ≤ 50mA.
5. Installation specifications:
   • Insertion length: 50 to 1000mm (customizable), insertion depth should be ≥ 10 times the diameter of the protective tube.
   • Installation methods: Threaded installation (M27*2, G1/2", G3/4"), flange installation (DN25, DN40), ferrule installation.
6. Environmental adaptability: Operating environment temperature -20℃ to 60℃, relative humidity ≤ 90%, vibration resistance level ≤ 2.5g.

• Black screen with no display: Battery dead (replace battery) or external power supply failure (check wiring); circuit damage requires return to factory for repair.
• Large reading deviation: Insufficient insertion depth (adjust installation depth), aging of temperature sensing element (replace) or calibration failure (re-calibrate).
• Display jumps: Electromagnetic interference (replace shielded wire) or poor sensor contact (check internal wiring).

• Industrial process monitoring: Real-time display of temperature in chemical pipelines, storage tanks, and reaction vessels, facilitating quick and accurate data reading by operators.
• Energy and power equipment: Monitoring of boiler water temperature, turbine lubricating oil temperature, and generator bearing temperature, with vibration-resistant design suitable for equipment operating environments.
• HVAC and refrigeration: Temperature display in central air conditioning water systems, cold storage facilities, and heat exchange stations. The LCD backlit model is suitable for dimly lit machine rooms.
• Food : Temperature monitoring of pharmaceutical reaction tanks and food processing equipment. The 316L stainless steel material meets hygiene requirements.
• Outdoor scenarios: Temperature measurement of environmental protection equipment and outdoor pipelines. The IP67 waterproof type can withstand rain and snow erosion.

The digital bimetallic thermometer represents a successful "intelligent" upgrade over traditional mechanical models. It effectively addresses the shortcomings of pointer-type instruments, such as being hard to read, inaccurate, and lacking in functions. By offering electronic display, it provides a superior user experience and higher reading accuracy. Additionally, it enables system integration through optional electrical signal output. It strikes an excellent balance between on-site indication and low-cost system integration. If you are in need of a thermometer that is easy to read and offers more diverse functions on-site, this is an ideal choice.
