The Ultimate Guide to Double Points Bimetal Thermometers: How They Work & Key Applications
In the world of industrial temperature monitoring, precision and reliability are non-negotiable. Among the various instruments available, Double Points Bimetal Thermometers stand out for their unique ability to provide dual-setpoint control in a single, robust device. This guide delves into their functionality and critical uses.
How Double Points Bimetal Thermometers Function
At their core, these thermometers operate on the classic bimetal strip principle. Two dissimilar metals bonded together coil or twist in response to temperature changes. The innovative “double points” feature integrates two independent electrical contact points within the mechanism.
Dual-Setpoint Alarm and Control Mechanism
Each contact point can be preset to a specific temperature threshold. When the temperature rises or falls to reach these setpoints, the contacts open or close, triggering alarms, activating cooling systems, or shutting down processes. This allows for both high-temperature and low-temperature monitoring from one installation.
Key Industrial Applications and Benefits
The dual functionality makes these instruments incredibly versatile for critical processes.
Preventing Equipment Failure in HVAC Systems
They are essential in HVAC and refrigeration, preventing compressor damage by signaling both overheating and excessive cooling.
Ensuring Process Safety in Manufacturing
In chemical processing or food production, they ensure product quality and safety by maintaining temperatures within a strict, predefined window, alerting operators if conditions drift outside safe limits.
