As a conductivity-based level switch

High-Temperature Durability: The Class H coil and EPR seals are specifically rated for steam and hot water applications

this assembly ensures a leak-proof seal and consistent flow under standard operating pressures of 20 to 90 psi

For larger 1/2" or 3/4" valves

a discharge air temperature sensor for high/low limit protection

Mitsubishi Electric SS610E Sensor 321042-401 As a conductivity-based level switchThe Mitsubishi Electric SS610E Sensor is a critical condensate overflow switch engineered specifically for ductless mini split systems. This high reliability drain pan water level sensor features solid state microelectronics with no moving parts, eliminating the mechanical failure points common in traditional float switches. Designed for seamless integration, it is fully compatible with Mitsubishi M Series (MSZ, MSY, MFZ), P Series (PKA), and CITY
