The TLV iT5-FF-SUN is a monitoring sensor designed for reliable, high-frequency monitoring of crucial steam-using equipment such as heat exchangers, presses and turbines, equipment in difficult-to-reach locations, or steam traps. It features surface temperature and ultrasonic measurement based on the FOUNDATION™ Fieldbus protocol.

Features

• High frequency monitoring: measurement cycles configurable between 1 and 15 seconds.
• Wired network connection enables reliable data communication.
• Surface temperature measurement up to 400 °C.
• Intrinsically safe construction for use in hazardous and non-hazardous locations.

Note

Steam trap diagnostic software is required separately. Contact TLV for details.
