The ZDTC9104/9204 series independent armored thermocouples and resistance temperature detectors feature a design where the sensing element of the armored thermocouple or RTD is directly in contact with the measured medium without the need for an additional protective sheath. This series is typically used in environments with mild conditions, where there is no abrasion, strong corrosion, or other special requirements, and where fast response times are necessary. Since they are fully armored, they offer advantages such as vibration resistance, flexibility, and compact size, making them suitable for confined spaces or areas with moderate vibration.
