The TLV iT5-IS-SUN iTrapSensor is a monitoring sensor with wireless communication designed for high-frequency monitoring of crucial steam-using equipment such as heat exchangers, presses, turbines, equipment in difficult-to-reach locations, or steam traps. Based on the ISA 100.11A protocol, it provides reliable wireless surface temperature and ultrasonic measurement.

Features

• High frequency monitoring: measurement cycles configurable between 1 second and 1 hour.
• Line-of-sight communication distance of 400 m between sensor and repeater or between repeaters.
• Powered by a long-life battery pack, replaceable in hazardous locations.
• Surface temperature measurement up to 400 °C.
• Intrinsically safe construction for use in hazardous and nonhazardous locations.
• Optional extended antenna type for remote antenna mounting.

INFO

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