Temperature Controller is an instrument that measures Temperature from sensor and based on the setpoint, takes action. Temperature Controller can be single, dual, tri, quad, hex options. ESD has many options in Temperature Controller category.

How does a Temperature Controller work?
Temperature Controller uses a micro-controller for reading the sensor value. Temperature Controller can either interface with a computer and use software to view and analyze the collected data or be used as a stand-alone device with a local interface or connect via RS485 two wire interface or wirelessly to a device and/or Cloud Server.
The advantage of Temperature Controller is that they can operate independently of a computer, unlike many other types of data acquisition devices. Temperature Controllers are available in various shapes and sizes. The range includes simple economical single channel fixed function Temperature Controller or devices capable of handling 2,3,4 inputs. The most common inputs to Temperature Controller are Temperature, Pressure, Humidity, Voltage, Current or any Digital Event. ESD make Temperature Controller are known for its relability, repeatablitiy, robust and proven field performance over the years.
