The SKP 850 electronic tensiometer is designed for field use and has a 0 to -999 HPa (mbar) measuring range.
The SKP 850 is a tensiometer with very fast response time. (Ceramic with very high flow)
The SKP 850 sensor has its own temperature correction (-10°C /+50°C).
The sensor is light (200 grs) and small. The SKP 850 sensor is compact, waterproof and is built for outdoor conditions.
The SKP 850 is made of stainless steel housing and white PVC shaft.
REMOVABLE POROUS CERAMIC (SDEC 7500)
MONITORING (integral pressure sensor)
Measuring range : 0 Hpa to -999 Hpa.
Output : The SKP 850 sensor exists in two versions : Differential voltage outPut . (0-100mV) : ref. SKP 850T Current loop outPut (4-20mA) : ref. SKP 850C2
Accuracy : better than 1% of full scale.
Pressure sensor : differential pressure type with integrated temperature compensation.
Offset : calibrated in our factory (SKP 850C2 sensor only; each sensor is delivered with an individual calibration certificate).
Preparation : By two capilaries tubes. One capilary is used as a purge tubing.Thanks to this purge system the SKP850 device water compartiment is free of parasitical air
Installation in the pot : since this tensiometer length is only 30 cm, it is possible to put it into the substratum without auger, by simply pushing it with the hand.
Electrical OUTPUT: On cable across nickel stuffing box.
Water refilling : by two Nylon capillaries.
Power supply : direct current; +6 to +15 Volts.
Electrical protection : the sensor is electronically protected against polarity reverse.
Temperature compensation : -10°C to +50°C.
Sensor case : Stainless steel 316 L, PVC and NYLON.
Dimensions : Ø = 20 mm. Lenght : 22 cm
Weight : about 200 gramms.
Operating temperature : -10°C à + 50°C.(with anti-freeze).
Storage temperature : -20°C à + 60°C.(without water inside sensor).
