2017 hot sell wall duct and immersion Digital Temperature Transmitter/Controller

 Multi functions design :

Models: TTD2N: Duct mount digital temp.transmitter 

                TTD3N:Outside air digital temp.transmitter 

                TTD4N:immersion digital temp.transmitter 

Application:

1. These transmitters/controllers can be used for temperature monitoring & controlling in duct air(TTD2N), water and steam pipe(TTD4N) or outside air(TTD3N)
2. High performance digital temperature sensor and digital technology applied, ensure accurate measurement fast response and good long term stability
3. Multiple outputs selection, over voltage and reverse polarity protection, high reliability and anti-interference capability
4. Optional relay for alarm or ON/OFF control
5. Wide working temperature range and fast response
6.  LCD & function keys can set parameters and calibrate output, so the product can become a stand alone controller
7. High protection rate up to IP65
