Temperature Sensors - Thermostats - Mechanical
Definition:
Mechanical thermostats are temperature-sensing devices that utilize physical mechanisms to monitor and regulate temperature without relying on electronic components. These devices typically employ bimetallic strips, gas-filled bellows, or wax actuators to trigger mechanical switches, making them simple, durable, and cost-effective solutions for temperature control in various applications.
Types of Products in This Category:
1. Bimetallic Thermostats: Use two bonded metals with different thermal expansion rates to actuate a switch at a set temperature.
2. Gas-Actuated Thermostats: Rely on the expansion/contraction of gas-filled bellows to control electrical contacts.
3. Wax Thermostats: Utilize wax pellets that expand when heated, mechanically pushing a rod to open or close a circuit.
4. Line Voltage Thermostats: Designed to directly control high-voltage heating systems without requiring an external relay.
5. Snap-Disc Thermostats: Feature a pre-calibrated disc that snaps to break or make contact at specific temperatures.
Buying Recommendations:
- Application Compatibility: Ensure the thermostat s temperature range and switching capacity match your system requirements (e.g., HVAC, industrial equipment, or appliances).
- Durability: For harsh environments, opt for models with robust housings (e.g., stainless steel or weatherproof enclosures).
- Accuracy & Calibration: Mechanical thermostats have inherent hysteresis; verify tolerance levels ( 1 C to 5 C) align with your precision needs.
- Certifications: Check for industry-standard certifications (UL, CE, RoHS) to guarantee safety and compliance.
- Installation Type: Select surface-mount, immersion, or insertion models based on your mounting constraints.
Ideal for budget-conscious or high-reliability applications where simplicity is prioritized over programmability, mechanical thermostats remain a staple in temperature control systems.
