Temperature Sensor for SolarConverter products.


  • Highly stable and accurate voltage reference
  • Accurate over the full temperature range

Basic Operation

This product is an LM335Z precision temperature sensitive zener with wires attached and mounted to make it easy to mount and connect to.

Typically a thermistor is used to measure temperature. Unfortunately these are very non-linear and typically have enormous errors when operated far from their 25 Deg C ratings. At least 50 % measurement errors are not the least bit uncommon.

If an error of this magnitude is controlling the charge on the battery when faced with large temperature variations, proper temperature compensation is impossible.

The LM335Z is accurate to 2 % over the entire temperature range. When connected to Solar Converters Inc. products a true temperaure measurements results over the full temperature range in true temperature compensation. The result is that products such as the Solar Converters' MPPT charge controllers work more effectively by taking into account the ambient temperatures.

We highly recommend a temperature sensor if the environment for your batteries or system experiences fluctuations of more than 30 degrees Fahrenheit.

Special Shipping Note:
All Solar Converter Products are behind in production. These items are usually shipped directly from the manufacturer in Canada. They cannot be shipped by any expedited methods such as UPS Blue or Red. They will generally be shipped via Canadian Express Mail which avoids import brokerage fees of $50-$60. Lead time on these products may be up to 4-6 weeks depending on their production. This is true of all Solar Converters products with the exception of the battery desulphator (item code SORBD-2) that we stock in our warehouse. If you want Solar Converters products to be shipped by normal Canadian Post, but would prefer to have the rest of your order to be shipped by a faster method, please write this information in your order's notes during checkout.
