Digital AC Thermometer Circular Single Display Indicator Light

The YAMING Digital AC Thermometer Circular Single Display Indicator Light is a 22mm panel-mount, industrial-grade 2-in-1 indicator device that integrates equipment status display with high-precision temperature detection capabilities, serving as a direct replacement for traditional separate indicator lights and thermometers. Manufactured by Zhejiang Yaming Electric—a professional Chinese manufacturer with over 30 years of experience in the electrical industry—this product features an industrial-grade flame-retardant ABS housing and an optimized circuit design. It supports a wide AC voltage range of 50–380V, accurately measures temperatures within the range of -20°C to 199°C, and boasts a high-brightness LED digital display along with robust vibration resistance and wear resistance.


The YAMING Digital AC Thermometer Circular Single Display Indicator Light utilizes a standard 22mm panel cutout for a "plug-and-play" installation experience with simple wiring, requiring no complex calibration or commissioning. Unlike traditional single-function signal lights, this product visualizes real-time temperature data, performing the dual functions of status indication and precise temperature measurement. This effectively conserves cabinet space and reduces procurement costs, making it ideally suited for complex industrial operating environments and ensuring the long-term, continuous, and stable operation of equipment.


Core Product Features


1. 2-in-1 Multifunctional Integrated Design

It integrates the dual functions of equipment status indication and digital temperature detection, directly replacing separate indicator lights and thermometers. This simplifies the control system structure, saves over 30% of cabinet installation space, and simultaneously reduces procurement and maintenance costs, thereby meeting the design requirements of compact industrial control cabinets.


2. Standard 22mm Universal Mounting

The Digital AC Thermometer Circular Single Display Indicator Light adopts the industry-standard 22mm panel cutout design, ensuring compatibility with the vast majority of industrial control panels. Installation, replacement, and maintenance require no special tools, making it suitable for both new equipment installations and retrofitting existing systems, thereby significantly lowering the barrier to equipment upgrades.


3. Real-time, Precise Temperature Detection

It supports a wide industrial temperature monitoring range of -20°C to 199°C with high measurement accuracy. This allows for the rapid identification of potential overheating hazards in equipment—such as motors and control cabinets—effectively preventing burnout and system downtime failures to ensure continuous production operations.


4. High-Brightness LED HD Display

Equipped with a high-brightness LED digital display, it ensures clear readability even in harsh workshop environments characterized by dim lighting, intense glare, or heavy dust. Real-time temperature readings are instantly visible at a glance, enabling on-site personnel to quickly monitor equipment temperature status and detect anomalies in a timely manner.


5. Robust, Industrial-Grade Construction

Features a flame-retardant ABS industrial-grade housing that offers excellent resistance to shock, abrasion, and aging. It withstands daily wear and tear, mechanical vibrations, and complex operating conditions involving moisture and dust, making it ideally suited for rigorous industrial environments with a long service life.


6. Stable, Continuous, and Low-Power Operation

Optimized internal circuit architecture supports a wide AC voltage input range of 50–380V. With low power consumption (only 0.5W) and a low failure rate, it operates stably and continuously over extended periods, making it perfect for industrial production lines, automated equipment, and other scenarios requiring 24-hour uninterrupted operation.


Typical Application Case


Case Study: Temperature Monitoring for Automotive Parts Production Line Control Cabinets

An automotive parts manufacturing company in Zhejiang Province faced persistent issues with its production line control cabinets: temperature monitoring was often delayed, and traditional indicator lights offered only single-function capabilities. During peak summer heat, frequent overheating within the cabinets led to accelerated wiring degradation and equipment shutdowns, significantly impacting production efficiency.


Upon adopting the YAMING Digital AC Thermometer Circular Single Display Indicator Light, the units were installed on the control cabinet panels to provide real-time temperature monitoring. Timely warnings are now issued during high-temperature events, enabling maintenance personnel to quickly diagnose and resolve cooling system failures. Following this upgrade, the incidence of cabinet overheating faults dropped by 90%, and the stability of continuous equipment operation improved dramatically. The company now saves over 100,000 RMB annually in avoided production losses. Furthermore, the product's shock-resistant and wear-resistant properties are perfectly suited to the vibration-prone environment of the production line, ensuring trouble-free long-term operation.


Summary of Product Advantages


1.Functional Upgrade

Features a "two-in-one" integrated design that replaces separate devices, providing visual temperature data—a capability far superior to traditional single-function indicator lights.


2.Convenient and Efficient

Utilizes a standard 22mm mounting size for "plug-and-play" installation with simple wiring; no calibration or complex commissioning is required, thereby reducing installation and maintenance costs.


3.Stable and Reliable

Constructed from industrial-grade materials with an optimized circuit design, offering excellent resistance to shock and abrasion, low power consumption, and a low failure rate—making it highly adaptable to complex operating conditions and ensuring a long service life. 4. High Cost-Effectiveness: Combining high performance with reasonable pricing, this unit serves as an ideal choice for upgrading industrial equipment temperature control systems, effectively balancing both cost and benefit.
