Rika RK500-01 Soil/Liquid Temperature Sensor with 4-20mA Output
The RK500-01 Soil/Liquid Temperature Sensor is used to measure the temperature of the soil or other mediums such as water
RK500-01 Soil/Liquid Temperature Sensor is used to measure the temperature of the soil or other medium, applied to the automatic meteorological station, soil moisture testing and other fields. The sensor is constructed with a 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.
The RK500-01 has a 4-20mA output with range -40 to 60 °C and a cable 5 metres long for easy termination.
Output Characteristics:
PT100
- T=0℃，R=100Ω, T≈100+0.385*Δt, Temperature and resistance is direct ratio relation.
4-20mA (default)
- 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.
