Focusens PTC thermistor is a leader in the field of motor protection with excellent quality. Its core feature is the sudden increase in resistance at critical temperature. It is high quality and low price, and performs well in heavy-duty motors. To avoid the risk of direct interruption of large currents, the PTC sensor intelligently monitors the temperature and provides high-resistance protection when exceeding the threshold, safely cutting off the circuit and preventing the motor from overheating.
RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device. It does not produce an output on its own. External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage. Typically 1 mA or less measuring current, 5 mA maximum without the risk of self-heating.
The PTC thermistor sensor with a 3-wire series design ensures reliable motor and machine protection. It features precise temperature control, capable of withstanding up to 170°C. This sensor reacts quickly to temperature changes, preventing overheating and safeguarding your equipment. Its durable ceramic semiconductor construction guarantees long-lasting performance. Designed for easy installation, it suits various industrial applications. This PTC thermistor sensor is the ideal solution for those seeking efficient thermal management. Protect your motors and machinery with consistent and reliable temperature control.
