A/100-3W-S-4X - 100 Ohms @ 32 degrees F ( platinum RTD sensing element) with a 0.00385 temperature coefficient in a three wire configuration. The polycarbonate NEMA 4X strap on configuration has a sensor potted to the back side of a copper plate and a foam pad creates compression when the strap worm drive is tightened. The final result is a good thermal transfer with pipes that range from 2 to 5" in diameter. ACI Strap on temperature sensors are designed for HVAC or Building Automation Systems.  Specific applications include: chiller hot water system tank and boilers.

A/100-3W-S-GD - 100 Ohms @ 32 degrees F ( platinum RTD sensing element) with a 0.00385 temperature coefficient in a three wire configuration. The galvanized metal strap on configuration has a sensor potted to the back side of a copper plate and a foam pad creates compression when the strap worm drive is tightened. The final result is a good thermal transfer with pipes that range from 2 to 5" in diameter. ACI Strap on temperature sensors are designed for HVAC or Building Automation Systems.  Specific applications include: chiller hot water system tank and boilers.
