Product information "JUMO wall resistance thermometer with internal sensor Protection class IP65"
Room, outdoor and duct resistance thermometers
Typ: 902520/21-573-1003-1/000
- Measuring range from -30 to +90°C
- Measuring insert 1x temperature sensor Pt100 in two-wire circuit
- Transmitter: without
- Protection class IP65
- Suitable for use in air conditioning technology
Room, outdoor and duct resistance thermometers are designed for air conditioning technology and are mainly used for temperature measurement in rooms, air ducts and outdoors.
Various plastic device versions with different degrees of protection are available for the respective measuring task.
A Pt100 temperature sensor in accordance with DIN EN 60751 class B in a two-wire circuit is installed as standard, but variants with Pt500, Pt1000, Ni1000 and various NTC sensors are also possible. The connection terminals allow optional continuation in three- and four-wire circuits. An integrated measuring transducer can also be selected as an option.
