OEM China Suppliers Factory Stainless Steel 4 100mm Bi-metal Thermometer with Electric Switch Contacts for Industrial Automation Supplier, Suppliers

Introducing our high-quality electric contact bi-metal thermometer, designed for precision temperature measurement in various industrial applications. This reliable device utilizes a bimetallic coil combined with electrical contacts to activate alarms or control devices when predetermined temperature limits are reached. Ideal for sectors such as industrial automation, pipelines, boilers, and HVAC systems, it ensures efficient monitoring and automatic control of processes, Manufactured in China, our bi-metal thermometer with switch contacts is an essential tool wherever on-site temperature indication and circuit control are required. The adjustable switch contacts (electrical alarm contacts) respond dynamically based on the position of the indicator pointer, allowing for flexible monitoring across the full measurement range, The instrument features a freely moving actual value pointer that operates independently of the set pointer, which can be conveniently adjusted through a window with a removable tool. As reliable suppliers and factory manufacturers, we ensure that our products meet the highest quality standards for optimal performance in any application
