PENN Remote-Bulb Sensor Temperature Controls

These weatherproof temperature controls have a watertight enclosure and are ideal for cooling tower sump heaters, evaporative condensers, and heating and ventilation equipment. Their enclosures are rated NEMA 4X, so they're suitable for areas that are exposed to water spray, high humidity, airborne contaminants, and corrosive conditions. These controls are compatible with single-stage systems. Single-stage systems have a single output level and allow the system to be either on or off. These controls have a capillary tube and sensor that monitor and regulate the temperature of the ambient air, a liquid, or a gas at a distance away from the control. The sensing element is not affected by changes in barometric pressure or cross-ambient conditions to ensure accurate temperature regulation.
