Models 6507E, 6535A
The Thermistor Temperature Probes are designed for many applications of temperature measurement like air, water, soil, snow, ice, etc. They are fully sealed and can be used in fresh and sea water to a depth of 30 metres.
The thermistor temperature probes use a Negative Temperature Coefficient (NTC) thermistor as their temperature sensor. The NTC thermistor is a high quality, precision curve matched element. Its operating temperature is from -100°C to 150°C.
Consult the table of ranges below to determine which probe and reference resistor will best suit your project. The last listing is the theoretical maximum. Due to the type of cable being used the measurement range of the standard thermistor temperature probe is from -30°C to 100°C. Higher temperature values are quoted as a guide only.
Both models 6507D & 6507E offer improved accuracy (±0.1°C) and are ideally suited to measuring temperature profiles in water.
Temperature Ranges – Models 6507D & 6507E with 15k Reference Resistor
|Starlogger 6004D||Prologger 7001D|
For example, if you use a Model 6507E with the standard 15k reference resistor connected to a Starlogger and you require 0.5°C (or better) resolution, then the usable temperature range will be -9°C to 70°C. And the maximum theoretical temperature able to be registered would be 200°C, although the probe is not suitable for temperatures above 150°C.
The Linear Temperature Probe is used for measuring temperatures between -17.8°C and 100°C. It outputs a DC voltage, the value of which is directly proportional to temperature. This temperature probe is especially useful with the Standard Starlogger 6004D-1, Display Starlogger 6004D-2 and Prologger 7001D-1 since they can only display linear formulae.
