The DEWMAT 780 dewpoint sensor is a reliable and long-term stable dew point sensor for industrial applications.
It uses a completely new sensor technology delivering stable measurement signals, even when the humidity is very low, thus offering reliable and precise measurements up to dew temperatures of -100 ° C.
- Dewpoint measurement down to –100 ° C
- New sensor technology
- Variant with integrated pressure measurement
- Various output signals depending on the versions: 1 x 4 ... 20 mA, 2 x 4 ... 20 mA, RS-485 (Modbus), 4 ... 20 mA with loop power
- IP65 enclosure offering protection in restrictive industrial applications
- Very fast reaction times allow safe signaling when the limit values are exceeded
- Direct installation in a dryer possible via ½ "thread
- High precision, ± 2 ° C dew point.
