Thermostatic Sensors Type RA 2000
Application
RA 2990 |
RA 2992 |
The RA series is a comprehensive programme of radiator thermostats which covers all central and district heating systems.
RA is a self-actuating proportional controller with a small P-band.
The RA sensor range includes:
▪RA 2990: built-in sensor with frost protection, temperature range 5-26°C, facilities for limiting and locking the temperature set-point. A score on energy efficiency. RA 2990 and 2992 sensors are equipped with a snap-lock mechanism which ensures quick, firm and long lasting mounting of the sensor.
▪RA 2992: remote sensor with frost protection, temperature range 5-26°C, facilities for limiting and locking the temperature set-point.
▪RA 2920: Tamperproof model with built-in sensor, frost protection, temperature range 5-26°C, facilities for limiting and locking the temperature set-point.
▪RA 2922: Tamperproof model with remote sensor, frost protection, temperature range 5-26°C, facilities for limiting and locking the temperature set-point.
RA 2992 and 2922 are equipped with 2 m of ultrathin capillary tube, which is coiled up within the remote sensor housing. After sensor mounting capillary tube is pulled out to the required length.
|
▪ RA 5060 Series: remote temperature |
|
adjuster with frost protection. Temperature |
Approved to EN 215 |
Thermostatic sensors type RA 2000 are |
|
manufactured to the highest standards, |
|
and are approved to the European |
|
standard EN 215. |
RA 2920 |
RA 5060 |
range 8-28°C, facilities for limiting and locking the temperature set-point.
▪RA 5062: length of capillary tube 2 m
▪RA 5065: length of capillary tube 5 m
▪RA 5068: length of capillary tube 8 m
The snap-lock sensors are easy to mount and requires no use of tools.
The sensor is fitted to the valve by applying a gentle pressure. When the sensor is in place, the snap-on mechanism is activated and the sensor has been correctly mounted.
If mounting and dismounting are carried out again, the mechanism must be tightened manually by turning the tightening ring.
All thermostatic sensors can be combined with all RA 2000 valve bodies.
The technical data for RA valve bodies in combination with RA sensors meet Euronorm EN 215.

1)The remote sensor is delivered with all of the capillary tube coiled up within the sensor. When mounting the sensor, only the capillary tube required is uncoiled.
2)Temperatures stated for Xp = 2K, i.e. the valve is closed at 2 °C higher room temperature.
