SmartTemp SDI-12

Smart SDI-12/RS-485 Temperature Sensor

Part # 51163

digital temperature sensor compact

51163-300

digital temperature sensor compact

51163-300

The Smart Temp is a high precision digital temperature sensor that meets USGS guidelines. It features the ability to automatically sample temperature and calculate minimum, maximum, and average temperatures on a flexible time scale.

This sensor is ideal for high-accuracy readings in water, soil, and air. It features fully-potted components, robust PVC Type II housing, and marine-grade stainless steel, making the sensor ideal for harsh environments. Model 51163-300 is small enough to easily deploy through standard 1” (2.5cm) PVC conduit with 8” (20.3cm) factory bend corners. It also offers a loop hole which can be used to mount weights or pull the sensor through pipes or other small areas.

Model 51163-200 has a durable, marine-grade stainless steel tine for easy soil insertion.

SDI-12 output provides universal compatibility with any SDI-12- enabled data logger and low power applications, or use the standard SDI-12 command set over an RS-485 physical interface for applications that require long cable runs or many sensors.

  • Automatic minimum, maximum, and average calculations
  • RS-485 and SDI-12 interfaces (auto-detecting)
  • SDI-12 Ver 1.4 compliant
  • Firmware updates through RS-485
  • NIST certification available
  • High-accuracy temperature measurement
  • Extremely low current draw
  • Works in water, soil, or air
  • Suitable for freshwater or marine applications
  • Fully potted electronics
  • Tough PVC Type II housing
  • Celsius and Fahrenheit output
  • No calibration required

Easily deployed through standard 1” PVC conduit with 8” factory bend corners*

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
