Wysala DRYCAP® Dew Point transmitters DMT345 and DMT346 are designed for humidity measurement in industrial drying applications with high temperatures. The high temperature tolerance of the sensor enables direct measurement during high temperature processes without the need for sampling systems and sample pre-processing. DMT345 and DMT346 have a wide dynamic measurement range ranging from frost point -40°C to dew point up to 100°C, and dry bulb temperature range up to 350°C.

Recordable parameter	Maximum data trend/minimum value/maximum value can be recorded	Recording time interval	10 seconds (fixed interval)
Maximum recording period	Four years and five months	Point of record	13.7 million points each
Battery life	Minimum 5 years	Probe cable length	2 m, 5 m or 10 m
Weight (case)	1.2 kg	Material (shell)	G-AlSi 10 Mg (DIN 1725)

Main Advantages:

Reliable in high temperature process

The cooling system has no moving parts and requires no additional power supply or cooling device, so there is no risk of sensor damage due to mechanical cooling failure.

Wide dynamic range

Dew/frost point temperature measurements range from -40 to 100°C, with operating temperatures up to 350°C. This combination makes the sensor suitable for high-temperature and dynamic processes with a wide temperature and humidity range.

Easy to operate

A measurement and trend graphical display with a multilingual menu and keyboard enables users to easily monitor operational data, measure trends, and access measurement history over the past 12 months.

Both transmitters feature accurate, reliable and stable Vysala DRYCAP® sensors. The sensor is resistant to condensation and is not affected by particulate pollution, oil vapors and most chemicals. DRYCAP® sensors are widely recognized for their fast response time and ability to recover quickly when wet.
