Sensors
CS10 Solar cell
The solar cell is used for measuring the irradiation intensity. The short-circuit current rises with increasing irradiation intensity. Depending on the controller, the sensor can also be used for additional plausibility control or direct control. The connecting cable can be extended to 100 m.
High temperature sensors
For temperatures up to 300 °C
Pt1000 version
Note:
The temperature range refers to the insulation of the sensor cable!
Temperature sensors
For installation into immersion sleeves
Advice:
Each temperature sensor is packed separately. For larger orders please ask for special conditions!
Flatscrew sensors
For installation on plane surfaces
Pt1000 version
FRP11 Indoor temperature sensor
For installation on plane surfaces
Pt1000 version
Grundfos Direct Sensors™
VFS Grundfos Direct Sensors™ measure the temperature and the flow rate with a single measuring element. Based on the vortex principle, the sensor measures the flow rate by means of the pressure differences caused by the fluid turbulences occurring at the insert. Grundfos Direct Sensors™ can be used in aggressive media as well as in domestic water and thus are ideal for measuring the flow rate and the heat quantity in solar thermal and heating systems.
The digital VFD Grundfos Direct Sensors™ measure the temperature and the flow rate with a single measuring element and then transmit the measured values directly via the RESOL VBus® protocol. Grundfos Direct Sensors™ can be used in aggressive media as well as in domestic water and thus are ideal for measuring the flow rate and the heat quantity in solar thermal and heating systems. VFD 1 - 12 l are designed for systems with low flow rates. VFD 2 - 40 l are designed for systems with higher flow rates. The VFD 2 - 40 l fast is ideal for DHW exchange modules due to its high-speed reaction time.
RPS Grundfos Direct Sensors™ measure the temperature and the relative pressure with a single measuring element. They can be optimally used for leakage and overpressure monitoring. Grundfos Direct Sensors™ can be used in aggressive media as well as in domestic water and thus are ideal for the application in solar thermal and heating systems.
The digital RPD Grundfos Direct Sensors™ measure the temperature and the relative pressure with a single measuring element and then transmit the measured values directly via the RESOL VBus® protocol. They can be optimally used for leakage and overpressure monitoring. Grundfos Direct Sensors™ can be used in aggressive media as well as in domestic water and thus are ideal for the application in solar thermal and heating systems.

Temperature sensors completed with immersion sleeve and strain relief
SP10 Overvoltage protection
Overvoltage protection device placed in housing with outstanding design, suitable for mounting outdoors. We generally recommend installing the overvoltage protection in order to avoid overvoltage damage at collector sensors, e.g. caused by local lightning storms.
FAP13 Outdoor temperature sensor
The FAP13 is used for measuring the outdoor temperature with a platinum measuring element. The FAP13 is placed in a weather-resistant housing with outstanding design and is designed for mounting outdoors. Cable glands for the sensor cables at the bottom of the housing allow easy installation.
Cylindrical clip-on sensors
For surface mounting on tubes, incl. pipe-clip
Pt1000 version
T-piece sensor
T-piece sensor for mounting into pipes. The T-piece sensor in the immersion sleeve measures the temperature of the circulation medium.
Immersion sleeves
Brass, copper or stainless steel
Because of the short component length, it is
recommended to use the immersion sleeve TH30
with the temperature sensor FKP5,5 or FRP5,5.
Advice:
Standard-screw connection thread of the immersion sleeves ½"
Attention:
In case of domestic water installations only use stainless steel immersion sleeves.
