Product Overview
The WZPK-525U Bimetallic Thermometer with Electrical Contact is designed for industrial temperature monitoring and automatic control. It utilizes a bimetallic strip as the sensing element, which triggers electrical contacts to activate alarms or cut off circuits when temperature reaches preset limits. Its robust construction ensures resistance to water, corrosion, and vibration, making it suitable for industries like petroleum, chemical, and power generation.1626
Key Features
This thermometer offers clear on-site temperature display and supports automatic power interruption or alarm triggering. The contacts are durable and designed for long-term reliability. Multiple structural configurations are available to meet diverse installation needs. The protective tube is made of corrosion-resistant materials, ensuring stability in harsh conditions. It covers a wide measurement range from -80°C to 500°C for liquids, steam, and gases.3820
Working Principle
The WZPK-525U operates based on the thermal expansion difference of its bimetallic coil. Temperature changes cause the coil s free end to displace, rotating the pointer and activating the contacts. By connecting or disconnecting with preset upper/lower limits, it controls relays for automated processes. Optional silicone oil filling or separated display enhances vibration resistance.151621
Technical Specifications
It features a 100mm dial diameter with accuracy classes of 1.0 or 1.5. Operating conditions include ambient temperatures of -25°C to +55°C and humidity ≤85%. Switching differential and setpoint errors are within 1.5 times the basic error limit. Electrical ratings are 220V AC and 0.7A current. Customization requires details like dial size, temperature range, and mounting type.7918
