UMS SIS SMART IRRIGATION SENSOR

Granular matrix sensor with linear output signal. The SIS is a combination of the well-known Watermark( R) granular matrix soil moisture sensor type 200SS and a special amplifier which offers a fully linearised and temperature compensated DC-voltage output signal. The amplifier uses a new, patent pending technique for the accurate measurement of the sensor element. The linear voltage signal reduces the efforts for the electronic measuring equipment and cable connections. The temperature compensation directly picks up the soil temperature. Thus, the otherwise problematic temperature difference between logger and sensor is avoided. dvantages Linear Output Signal Temperature compensation Simple power supply Low power Programable irrigation output signal* Serial buslink tensioLINK* Temperature serial readout* Limitations Generally lower accuracy compared with Tensiometers Slow response time particular in dry soil Technical Information Measuring range -5kPa...-200 kPa Resolution ± 0.2 kPa ( 5...70 kPa) Temperature* ± 0.1degC ( -10...30degC) Alarm signal* 0 V; + 5 V, 2 thresholds with hysteresis, Impedance: 10 kOhm Supply 6 ... 20 VDC, typ. 2, 5 mA Interface* RS 485 / tensioLINK Matrix Sensor Watermark, 200SS Size Ø 25 mm x 116 mm Untuk Info dan Pemesanan Hubungi : DARMATEK Contact : Subarkah Telpon : 021-71031268 Fax : 021-78890541 H P : 081283804273/ 085774067221 Email : subarkah18@ yahoo.co.id Gmail : darmatek1@ gmail.com Pin BB : 7512CBB7 Y M : cs_ darmatek Web : http: / / www.darmatek.com Link : http: / / darmatek.indonetwork.co.id http: / / darmatek01@ blogspot.com
