I. Overview
The PTWD series temperature sensors produced and designed by the company are packaged in stainless steel and have good waterproof performance. They are connected using high-quality cables and have a simple structure that is easy to install and replace. At the same time, sensors with various accuracies and measurement ranges are designed according to the usage scope and situation, saving resources for users and improving the cost-effectiveness of products.

2、 Basic principles
The PTWD series temperature sensor uses a precision platinum resistor as the sensing component, which is located at the head of the rod. It can be used to accurately measure soil temperature, and the accuracy and stability of the sensor depend on the characteristics and accuracy level of the Pt-100 platinum resistance element. Connect the ground temperature transmitter to an automatic weather station to measure surface, shallow, and deep ground temperatures.

3、 Typical applications
Widely used in meteorological station environmental temperature measurement, ground temperature measurement, water temperature measurement, greenhouse monitoring, and can be used in conjunction with collectors for large-scale multi-point remote monitoring.
