The TLV iT5-IS-TPN TrapSensor is a wireless monitoring sensor designed for high-frequency monitoring of crucial steam-using equipment such as heat exchangers, pumps, turbines, and equipment with the possibility of air present in steam piping. It provides simultaneous temperature and pressure measurement based on the ISA 100.11A communication protocol.

Features

• Simultaneous temperature and pressure measurement.
• 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.
• Temperature measurement up to 400 °C.
• Intrinsically safe construction for use in hazardous and nonhazardous locations.
• Optional extended antenna type for remote antenna mounting.
