TT30 HVAC and Clean Industrial Temperature Transmitter

The temperature control of ventilation and cold-hot water pipes in HVAC and clean industrial air conditioning systems is very important. In addition, temperature monitoring in clean rooms is critical to the stable operation of air conditioning systems.

TT40 temperature and humidity transmitter is very suitable for this application. The installation methods include wall type, pipe type (air pipe, water pipe), split type, wall-mounted split type, etc., which can meet the basic needs of HVAC and clean industrial air conditioning for the installation, and the wall-mounted split type is very appropriate for biopharmaceutical clean room EMS environmental temperature monitoring.

     TT40 has a variety of output signals to choose from: primary temperature element output, 4...20mA current output, 0-10V voltage output or RS485 output. In addition, TT40 can choose the display module, which is convenient for field monitoring.
