SMT50

The new SMT50 now available!

The SMT50 is designed and manufactured by TRUEBNER. It is a low cost FDR soil moisture sensor.

Compact, functional and robust: The PCB board based design allows for an economic design, and the blade shape facilitates installation. The casing and cable is water sealed.

The SMT50 has a broad measurement range. It is maintenance free and frost resistant. With short response times and low disturbance by salinity it is designed for a long term observation.

SMT100

The SMT100, designed and manufactured by TRUEBNER, combines the advantages of the low cost FDR sensor systems with the accuracy of a TDR system. Like a TDR, it measures the travel  time of a signal to determine the dielectric constant of the soil. And like a FDR, it converts this dielectric constant into an easy to measure frequency. But unlike an FDR it isn’t based on a capacitor, but utilizes a ring oscillator to transform the signal’s travel time into the measure frequency. The resulting frequency (>100 MHz) is high enough to operate well in clayey soils.

AquaFlex

The sensor AquaFlex of TRUEBNER is used to measure the average soil moisture along a 3 m special measuring cable . Unlike point- measuring sensors such as the SMT100 the moisture is measured in a very large measurement volume . Single wet or dry spots are no longer an issue with the irrigation of lawns. The sensor AquaFlex is ideal for easy installation into an existing lawn . The special measuring cable has a robust jacket of polyethylene and is very durable . With special calibration this sensor is also suitable for use in construction.
