COLUMBUS ELECTRIC Remote-Bulb Sensor Temperature Controls

These temperature controls are suitable for use in hazardous locations, like grain elevators, chemical plants, and mines. They control temperatures in Class I, Group D and Class II, Groups E, F, and G hazardous locations. Class I, Group D hazardous locations are areas where flammable gases or vapors may be present. Class II, Groups E, F, and G hazardous locations are areas where combustible dust may be present. 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.
