ETC-T300 (replacement for obsolete Danfoss THERM3)
ETC–T300
Replacement for obsolete Danfoss THERM3
3-wire Temperature thermistor with 20' lead; -25 to 125. Suitable for Danfoss NC25 / AKC25 installations
The ETC-T300 is an extremely accurate thermistor packaged in a water tight thin walled nickel plated brass Deep Drawn Tube. The sensor is potted with a thermal transfer epoxy to guarantee durability and response. The accuracy of the sensor is ±0.4ºF which allows the units to be interchanged in the field. The unit is a double thermistor providing a linear response over the range. The unit input is 5.00 vdc. The voltage output over the range is .726 to 3.523. At 50°F the voltage output is 2.123 vdc.
