WS433EX-PPS is the Sub-GHz Integrated Process Pressure Sensor with Ex d approval for installation in Zone 1, Zone 2, or Safe Zone. It has different measurements, such as Gage/ Absolute/ Sealed Gage, range -1∼1000 bar, high accuracy, and stability. With an Ultra-low-power design and smart firmware, the sensor can last up to 10 years with a single C battery (depends on configuration). The sensor will connect to a Wireless Coordinator WS433-CL or iConnector with the built-in wireless coordinator.
Typical applications are pressure monitoring of oil pipelines, gas pipelines, LPG tanks, CNG tanks, etc.
