Temperature Instruments

What are Temperature Instruments?

Temperature Instruments are essential devices used to measure, monitor, and control temperature in industrial processes.
They ensure equipment safety, production stability, and energy efficiency by converting temperature variations into readable or controllable signals.

Types of Temperature Instruments

1. Temperature Controller

A Temperature Controller regulates the temperature of a process by comparing the setpoint with the actual temperature and sending output signals to heating or cooling elements.
ZINACA offers digital, PID, and smart controllers for precise control in automation systems.

2. Temperature Transmitter

A Temperature Transmitter converts the signal from a thermocouple or RTD into a standardized output (such as 4–20 mA or RS485 Modbus).
It features high accuracy, long-term stability, and compact design, suitable for continuous temperature monitoring.

3. Temperature Switch

A Temperature Switch automatically activates or deactivates electrical circuits when the temperature reaches a preset limit.
It provides on/off temperature control for compressors, motors, and heating systems.

4. Thermocouple

A Thermocouple measures temperature using two dissimilar metal wires joined at one end.
It offers wide measuring ranges, fast response, and durability, commonly used in furnaces, boilers, and industrial heating processes.
Available types include K, J, T, E, and N thermocouples.

5. RTD (Resistance Temperature Detector)

An RTD measures temperature based on the resistance change of a metal (commonly platinum, such as PT100 or PT1000).
It provides high precision and excellent repeatability, making it ideal for laboratory, pharmaceutical, and food-grade applications.
