HTM208L low power temperature sensor is designed for measuring fluid temperature using a high-quality and high-stability PT100 or PT1000 sensing element. The sensor converts the temperature signal into a standard RS485 signal output through a signal conditioning circuit, enabling accurate temperature measurement.


What sets the HTM208L apart is its low power consumption and long service life. The sensor is powered by a built-in lithium battery, which provides the necessary power while consuming minimal energy. This allows for extended operation without frequent battery replacements, enhancing the convenience and cost-effectiveness of the product.


In addition to its low power design, the HTM208L features an on-site display, allowing users to directly view the temperature readings. Furthermore, the sensor can be networked through RS485 communication, enabling integration with other devices and systems for centralized monitoring and control of temperature data.


For added flexibility, the HTM208L can also be equipped with a wireless module, enabling wireless transmission of temperature data. This wireless capability eliminates the need for physical wiring connections, offering convenience and versatility in various monitoring applications.
