Product Overview:
The WZPK-204S Electrical Contact Bimetal Thermometer is a mechanical temperature measurement instrument specifically designed for industrial process control. Combining bimetal strip sensing technology with an electrical contact system, this device utilizes physical deformation to drive pointer movement for temperature indication. The adjustable contact mechanism generates switch signals at preset temperature points, enabling automatic monitoring of equipment status. It is particularly suitable for industrial applications requiring bidirectional temperature control.
Technical Highlights:
Constructed with 316 stainless steel housing and tempered glass cover, the instrument demonstrates excellent resistance to moisture, dust, and mild chemical corrosion. The dual-sealed structure achieves IP65 protection rating, ensuring long-term stability of internal components. The anti-glare matte dial with high-contrast markings guarantees legibility under various lighting conditions. The rotary magnetic contact adjustment system allows ±1% full-scale contact position fine-tuning, enabling quick temperature setpoint configuration via external knob.
Application Scenarios:
This product serves multiple industries including petrochemical plant reactor safety interlock systems, food sterilization equipment monitoring, HVAC chiller unit control, power transformer oil temperature protection, and laboratory thermal management modules. The passive contact design supports integration with PLCs and relay control systems, offering flexible NO/NC contact configurations.
Key Parameters:
- Temperature range: -80℃ to +500℃ (customizable segments)
- Accuracy class: 1.5
- Contact capacity: 220VAC/3A (resistive load)
- Stem length: 100-1000mm (optional)
