Ansul Rate Compensated Thermal Detectors

Rate Compensated Thermal Detectors are designed to compensate for thermal lag. When a rate-compensation heat detector operates, the actual operating temperature will be approximately equal to the rated operating temperature, regardless of the rate at which the air is being heated. The rate-compensation detector consists of a pair of expansion struts and electrical contacts enclosed by an expansion shell.
