HOFFER-HFTT TEMPERATURE TRANSMITTER

HFTT temperature transmitter measures the temperature of all kinds of media. The host of HFTT can easily program the temperature data, so as to realize the field debugging and application communication.HFTT installation mode can choose "all-in-one" or "split". Temperature transmitter uses 4-20mA transmission; Modbus RS-485 can also be used to transfer anywhere. HFTT can be selected IP65, the sensor component is suitable for Wet environment or underground mining.

Compared with the traditional temperature measurement method, HFTT temperature transmitter has obvious advantages:

1) HFTT has no moving parts in the container of the medium, so it has high reliability, long service life and no routine maintenance.

2) Its temperature measurement accuracy is high, good repeatability, can be in a relatively large range ratio range, to achieve high accuracy of medium temperature direct measurement.

3) HFTT can measure a wide range of media types, in addition to gas, liquid, but also can measure solid, various sports equipment and so on.

4) HFTT can meet various communication requirements and is suitable for data interaction with various systems.

At present, HFTT temperature transmitter is widely used in: industrial manufacturing, mining, petroleum, chemical, medicine, electronics, ship, water treatment, data room, building and other industries.
