Integrated temperature transmitter principle - Huaqiang Electronic Network

Photocoupler

Integrated temperature transmitter details:

The device operates on either +12VDC or +24VDC ±10% and offers output signals of 4-20mA or 0-5V, depending on the application. It provides high measurement accuracy: for thermistors, it's 0.2–0.3%, and for thermocouples, it's 1–2°C. The measurement range includes PT100 from -200 to 650°C, and CU50 from -50 to 150°C.

This temperature transmission module is designed to accept input from both thermistors and various thermocouple types. It can be directly connected to thermocouples and thermistors in junction boxes, forming an integrated structure. By using advanced circuit integration technology, it converts sensor signals into standard voltage or current outputs. The product is widely used in industries such as petroleum, chemical, metallurgy, power stations, and medicine, and is compatible with a variety of electric instruments, digital displays, and computer control systems.

Key features include:

• Ultra-small size (Ф44×18 mm) with high versatility.
• Two-wire 4–20mA DC output for long-distance transmission and strong anti-interference capability.
• High measurement accuracy, long-term stability, and maintenance-free operation.
• Internally filled with epoxy resin for use in harsh and hazardous environments.
• Integrated design with a simple and efficient structure, allowing direct replacement of traditional assembled thermocouples and thermistors.
