Description
Description
Hygrometer converts temperature or humidity to a 4 ... 20 mA signal / high precision / supply via current loop / wall mounting
The hygrometer was developed and constructed for the permanent monitoring of temperature or humidity. The compact dimensions of the hygrometer are the characteristics of this instrument. The measurement of the temperature and humidity is via a semiconductor component. Internally, the physical quantities to be measured are converted toa 4 ... 20 mA standard signal. The power of this measuring instrument is connected to a DC voltage into a current loop and is thus ideally suited for displays with transmitter power supply. But it can also be connected to the paperless recorder for long-term monitoring of environmental conditions.
Highlights
- sensor for temperature and humidity
- 4 ... 20 mA output
- easy wall mounting
- for permanent monitoring
- various filters available
- small size
