LFW21 Integrated Temperature Transmitter uses a high-resolution and high-precision temperature transducer as the measuring element. The amplifier circuit is located in a 304 stainless steel housing to convert the sensor signal into an analog signal output. This stainless steel temperature sensor is widely used in temperature measurement at industrial sites such as petroleum, chemical industry, electric power, hydrology, etc.
Feature
* With reverse connection and overvoltage protection;
* Small size, light weight, easy to install;
* Suitable for temperature measurement of fluid media, able to work stably for a long time.
