TESTO has released the 6740 pressure dew point transmitter. Pressure dew points from -60ºC to 30°C are transmitted via an analogue 4mA-20mA signal.
In addition, two alarms are freely selectable. Pressure tightness can up to 70 bar and an optional display is available with operating buttons around the picture. The unit prevents damage caused by a compressed air system overloaded with condensate. It also reduces the repair and maintenance costs of damage caused by ice and corrosion.
