OHD3-120M Classification

Temperature Sensors - Thermostats - Mechanical

Temperature Sensors - Thermostats - Mechanical is a device that senses environmental temperature changes and controls equipment operation through mechanical principles. Its core components include temperature sensing elements, mechanical actuators, and regulating mechanisms. Temperature sensing elements (such as bimetallic sheets and liquid expansion elements) undergo physical deformation with temperature changes, driving mechanical actuators (such as contact switches) to operate, thereby controlling the on/off of circuits and achieving automatic temperature regulation. Mechanical temperature controllers are widely used in various scenarios that require temperature control due to their simple structure, low cost, and high reliability.

FAQ about Temperature Sensors - Thermostats - Mechanical

  • 1. What temperature sensor does the thermostat use?

    The thermostat mainly uses thermocouples and PT100 temperature sensors. Thermocouple sensors are usually packaged in a stainless steel shell, filled with thermal conductive materials and sealing materials. They are suitable for a variety of temperature measurement scenarios, have a fast response speed, and are suitable for medical, HVAC, refrigeration, environmental experiments and other fields. 1. The PT100 sensor is a high-precision temperature sensor, often used in precision thermostat equipment.

  • 2. What are the 4 types of temperature sensors?

    There are four main types of temperature sensors:
    Thermocouple sensor: A thermocouple is a temperature sensing element that forms a closed loop through two conductors of different materials. When there is a temperature gradient at both ends, a current will flow through the loop, generating a thermoelectric potential signal, thereby measuring the temperature. Thermocouples have a wide temperature measurement range, but there are problems such as low sensitivity, low stability, and slow response speed.
    Thermistor sensor: The main component of thermistor sensor is thermistor. When there is thermal radiation around the thermosensitive material, it will absorb the radiant heat, causing the material resistance to change. Thermistors are usually made of polymer or ceramic materials and have a nonlinear temperature-resistance relationship, which requires correction to correctly interpret the data. Thermistors are suitable for highly sensitive and small temperature measurement occasions and are inexpensive.
    Resistance temperature detector (RTD): RTD usually uses metals such as platinum, copper or nickel. The resistance of these metals changes with temperature, has a large temperature coefficient and a fast response speed. RTD has a wide temperature measurement range, can resist thermal fatigue, and is suitable for precision measurement.
    Integrated Circuit (IC) Temperature Sensor: IC temperature sensor is made of silicon semiconductor integration process, with the characteristics of single function, small temperature measurement error, low price, fast response speed, long transmission distance, etc. IC sensor is suitable for long-distance temperature measurement and control, does not require nonlinear calibration, and has simple peripheral circuit.

  • 3. How does a thermostat sensor work?

    The working principle of a thermostat sensor is to detect the ambient temperature and adjust the temperature accordingly to keep it constant. Thermostat sensors usually consist of two main parts: temperature detection circuit and temperature compensation for the detection circuit.
    Working principle
    Temperature detection: The core component inside the thermostat sensor is a resistor, whose resistance changes with the change of the measured ambient temperature. When the ambient temperature rises, the resistance of the resistor changes, and this change can be converted into an electrical signal through the circuit.
    Signal processing: After the changing resistance value is processed by the circuit, a voltage signal related to temperature can be generated. This signal is amplified and processed, and finally outputs a current signal to control the temperature adjustment of the thermostat.
    Types
    There are two main types of thermostat sensors:
    Thermal resistors: Thermistors are usually used to achieve temperature detection, and their resistance changes with temperature.
    Thermocouples: They are composed of two metal wires of different materials, and obtain temperature information by measuring the potential difference between the two metals.
