Rika - Model RK500-01 -Soil / Liquid Temperature Sensors
RK500-01 Soil/Liquid Temperature Sensor is used to measure the temperature of the soil or liquid medium, applied to the automatic meteorological station, soil temperature testing, pond or reservoir water temperature detection and other fields.The products can be used into the water or buried in the soil.Sensor with precision thermal resistance as a sensing component, built-in signal sampling and amplification, zero drift and temperature compensation function, has the characteristics of high measuring precision and good stability.
- Real-time temperature measurement
- Good corrosion resistance, suitable for all kind of soil
- High accuracy
- Good linearity
- All stainless steel probe
- Environmental monitoring
- Weather station
- Aquaculture
- Ground temperature detection
- Water conservancy

PT100
T=0℃，R=100Ω, T≈100+0.385*Δt, Temperature and resistance is direct ratio relation.
4-20mA
T=((Iout-4)/(20-4))*(Range_max-Range_min)+Range_min
0-5V
T=(Vout/5)*(Range_max-Range_min)+Range_min
RS485
If the transmission distance is over 100m, please add a 120Ω terminal matching resistances on the front end and back end of bus interface respectively.See the modbus communication protocol specification.
