For use in solar water heater collector manifolds High Temperature Resistance Fits into thermowells as small as 7mm ID RTS (Resistance Temperature Sensor) 1 Meter long sensor wire (use Duda Energy copper wire for extensions) Digital Solar Water Heater Sensors RTS (Resistance Temperature Sensor) by Duda Energy p1000 Collector Sensor The pt1000 sensor is compatible with high temperature applications, typically for use in solar water collectors where temperautres may exceed 100°C. Duda Solar manifolds have a sensor port which this sensor easily slides into. 10k, B=3950 Tank/Pipe Sensor The 10k sensor is intended for solar water heater tank or pipe applications, where temperatures should not exceed 100°C. It may be installed into Duda Solar tanks by sliding into the sensor ports or may be used in conjunction with a an alternative thermowell plumbed into a water port on the tank or directly in a pipeline. For use in thermowells with up to 7mm ID. Compatible with most solar water controllers which use RTS for temperature sensing.
