Hydrolevel EL1214 Sensing Probe Els PW 17895 When replacing Hart or ProctorThe Hydrolevel EL1214 (also identified as Part Number 45 214) is a heavy duty 3 4" NPT standard ceramic sensing probe engineered for precise liquid level detection in residential and light commercial boiler systems. Featuring a 2 7 8" insertion length (inside dimension), this probe is a critical component for low water cut off (LWCO) safety controls, providing the essential conductance signal required to prevent dry firing and catastrophic heat
