The 210-101W Water or Soil Temperature Sensor is a rugged and reliable device for highly accurate submersible water temperature or soil temperature measurement. It produces a 4-20 mA output signal, which is an industrial standard for process control monitoring. Most PLCs (Programmable Logic Controllers), SCADA equipment, and data acquisition systems accept this signal directly.
If a voltage signal is required, the sensor output may be converted by reading the voltage across a precision resistor in series with the signal wire. When the 4-20 mA signal is dropped across a 250 ohm resistor, the output will be 1-5 Vdc.
The 210-101W sensor probe is molded to 25 feet of marine grade FEP jacketed 2-conductor 20AWG MIL spec MS22759 wire, suitable for direct burial. Additional cable lengths are available in 25 foot increments up to 500 feet.
The 210-101W has a two-wire configuration, 4-20 mA loop power. The unit's electronics are completely encapsulated in water-resistant potting compound inside the stainless steel housing.
