China Stainless Steel 4 100mm Bi-metal Thermometer with Electric Switch Contacts - China Suppliers & Factory Quality Manufacturer, Suppliers

Introducing our advanced electric contact bi-metal thermometer, expertly designed for precise temperature measurement using a bimetallic coil. This innovative thermometer features electrical contacts that trigger alarms or control various devices when specific temperature limits are reached. It is the perfect solution for industrial automation, pipelines, boilers, and HVAC systems, ensuring efficient on-signaling for automatic control, Ideal for situations where on-site process temperatures must be indicated while simultaneously switching circuits, our bi-metal thermometer with switch contacts is a reliable choice. The integrated switch contacts (electrical alarm contacts) facilitate circuit connections based on the pointer's position on the measuring instrument. These contacts are fully adjustable across the entire measuring range, allowing for versatile applications, Our thermometer's instrument pointer (actual value pointer) moves smoothly across the scale, functioning independently of the set settings. The set pointer can be conveniently adjusted through the window using a removable adjustment key, enhancing usability and flexibility, As a leading manufacturer and supplier in China, we guarantee top-quality products from our factory. Choose our electric contact bi-metal thermometer for robust performance and reliability in your industrial processes
