NovaLynx offers a wide variety of temperature probes for air, water, and soil temperature measurements. Most of the probes will interface to various data loggers with some additional external conditioning resistors. Some of the probes require signal conditioning to produce a linear analog output, i.e. 0-5 Vdc or 4-20 mA. For correct air temperature measurements the probes should be placed in a solar radiation shield. NovaLynx offers a variety of solar radiation shields to choose from.
The 210-301 Temperature Sensor is a three-terminal integrated circuit sensor whose output voltage is linearly proportional to the Fahrenheit temperature. This sensor does not require any external calibration or trimming to provide typical accuracies of ± 0.5°F at room temperature and ± 1.5°F over a full 0-120°F temperature range. It operates from 5-30 Vdc and has a linear 10mV/°F output. With a common reference to input and output, it easily interfaces with most dataloggers and outputs a direct reading analog output, i.e. 0.8 Vdc = 80°F.
The 210-4470 Platinum Resistance Temperature Probes can input directly to a temperature recorder or to a signal conditioning module to provide an analog voltage output proportional to temperature. The 99.99% pure platinum wire has a resistance of 100 ohms at 0°C. The platinum element is encased in a 6 long stainless steel housing and the cable is sealed to prevent moisture intrusion. Other probe configurations (piercing models, thermowell adapters, etc.) are available on special order.
The 210-4480 Series Thermistor Probes incorporate a 3-element thermistor composite and its measuring range is -50°C to +50°C when used in conjunction with the thermolinear network.
