Temperature Sensors - NTC Thermistors are temperature sensitive elements which exploit a thermistor’s negative temperature coefficient (NTC) to produce an electrical signal proportional to the temperature experienced by the thermistor. The NTC thermistors used in temperature sensing and control usually have a resistance value of 100 to 500 ohms at 25°C , and the resistance will decrease when the temperature rises. The most common application of a NTC thermistor is in a TTS-2KC3-BZ temperature sensing circuit.

The TTS-2KC3-BZ is a two wire, closed loop control circuit with a double sensing head in a single compact unit. It is designed for operation over a wide range of temperatures and is suitable for a variety of temperature control applications. The TTS-2KC3-BZ features two independent temperature sensing elements (one sense and one control) and two independent temperature control outputs. The sense element is a 100 ohms NTC thermistor, which is located in the sensing head, and the control element is a metal film resistor, which is located in the control head.

The TTS-2KC3-BZ circuit works by measuring the voltage across the sense element, the NTC thermistor. When the sensing element senses a change in temperature, its resistance changes, causing a voltage drop across the sense element, which is measured by the circuit. The circuit then adjusts the control element, the metal film resistor, in order to maintain a constant voltage across the sense element. In this way, the circuit maintains a constant temperature, regardless of the ambient temperature. This is what makes it suitable for a variety of temperature control applications.

The main advantage of the TTS-2KC3-BZ is its ability to operate over a wide temperature range, as well as the fact that it requires minimal circuitry, making it highly efficient and cost effective. Additionally, the flexibility of the circuit allows it to be used in both industrial and consumer applications. Examples of applications include, but are not limited to, precision temperature measurement in chambers or ovens, heat tracing systems, pipeline tracing systems, and temperature regulation of food service equipment.

In summary, the TTS-2KC3-BZ is a cost-effective and efficient temperature sensing circuit that makes use of an NTC thermistor to regulate temperatures over a wide temperature range. It is suitable for a variety of temperature control applications in both industrial and consumer settings. The simplicity of the circuit design, combined with its ability to operate over a wide temperature range, makes it a popular choice for temperature sensing applications.
