The progressive thermistor strings systems from GeoPrecision

The digital thermistor strings from GeoPrecision are the smartest solution on the market with bidirectional low-power wireless transmission (433/915 MHz) and four types of digital sensors with differing accuracy and precision.

All thermistor strings are custom manufactured to user specifications. Position, accuracy and sensor numbers are flexible. Very cost effective solutions are possible (depending on accuracy and sensor type) The thermistor strings are manufactured according to customer requirements for overall length, number of sensors and accuracy. Temperature points are over-molded to provide long-term protection in all mediums. So the thermistor strings are fully resistance to the ingress of water (IP69).

It is possible any combination of up to 48 sensors on a 100 meter cable. The minimum distance between the sensors is 15 cm - the distance between the first two sensors could be 10 cm.

The thermistor strings from GeoPrecision are using a special 2-wire bus. Therefor all measures data are sending digital to the data loggers.
