Application of industrial automation sensors

Temperature sensors include various devices ranging positive coefficient to negative coefficient type RTD (resistance temperature detector).

A positive temperature coefficient (PTC) thermistor is a resistor with a positive temperature coefficient, the resistance value increases with increasing temperature. These resistors are usually made of silicon to obtain linear characteristics. In contrast, the switched PCT thermistor has a non-linear temperature measurement curve. When the thermistor heats up, the resistance value decreases until it reaches the critical temperature. After the critical temperature is exceeded, the resistance value increases.

These devices are used in the windings of motors in industrial equipment, plus a monitoring relay to provide overheat protection prevent insulation damage. The nonlinear response curve causes the resistance value to increase sharply when the winding temperature reaches the allowable value, triggering the relay to prevent overheating. So you can connect to the wireless sensor network.

Negative temperature coefficient (NTC) thermistor, its resistance value decreases with the increase of temperature, the measurement accuracy in the range of 0°C ~ 70°C is +/- 0.1℃ +/- 0.2℃, with Good long-term stability.

These devices are commonly used in thermistor probe assemblies for fault diagnosis in industrial IoT smart factories. The thermistor sensor element can be used to monitor various systems connect the wireless sensor system to the cloud.

Inductive proximity sensors can detect metal approaching behavior, making the human machine interface (HMI) more secure. There are 2 3 wire DC versions, sensors with independent amplifiers to achieve high-speed operation.

The lidar sensor can be used for target detection in a one-dimensional topology, such as an infrared motion sensor on a conveyor line. The two-dimensional laser ranging sensor can be used as a position sensor to identify the position of the parts on the production line.
