The UT35A-L provides fail-safe protection to your process, preventing damage to equipment and product. It will shut down your process when the preset temperature value is reached and cannot be reset by the operator until the process has returned to a safe condition. The UT35A-L has a register function that indicates the maximum temperature reached and a timer function that counts the duration time that the setpoint was exceeded. Limit control is made simple and safe with the UT35A-L.
