PWS-100 Precision Scale

The PWS-100 Precision Scale continuously measures applied irrigation quantities or rates of transpiration in small to medium size potted plants. Plants are placed on the scale and the weight is transmitted continuously at user defined intervals. The amount of weight over time is a direct measure of water applied to, or loss from the plant.

The ICT PWS-100 incorporates a high performance, IP66 rated single point load cell with rated capacity of 100kg; special humidity resistant protective load cell coating assures long term stability over the entire compensated temperature range. Providing serial SDI-12 output, multiple PWS-100 can be easily bussed together and connected to an S-NODE or MFR-NODE (depending on other sensors in use), the PWS includes a 5m Cable for easy connections.

An optional configuration is the PWS-Tray/PRS1 that includes a tray for the measurement of through drainage.

Applications:

• Transpiration Rates of Plants
• Calibration of Sap Flow Meters
• Gravimetric weight monitoring
• Pressure Volume Curves
• Irrigation Monitoring

The MFR-NODE (LoRaWAN or CATM1/NB-IoT) supports up to 2 x PWS-100

The S-NODE (LoRaWAN or CATM1/NB-IoT) supports up to 4 x PWS-100 (additional sensors can be supported with external IB8 SDI-12 Bus)
